Dietary Supplements: Legislative
and Regulatory Status
Summary
Congress enacted the Dietary Supplement Health and Education Act (DSHEA)
of 1994. DSHEA addressed supplement definitions, safety, ingredient and nutrition
labeling, supplement claims, good manufacturing practices, statements of nutritional
support, new dietary ingredients, created a supplement commission, and established
an Office of Dietary Supplements at the National Institutes of Health.
Since DSHEA’s passage, which changed the safety standard and placed the
burden of proof for supplement safety on the agency, FDA has issued alerts on
several supplements to warn consumers of possible safety problems. The agency has
received hundreds of adverse reports allegedly caused by the use of ephedrine
alkaloids, although no final action has been taken on regulating this product. The
Inspector General has issued a report that evaluates and makes recommendations on
the effectiveness of the supplement adverse event reporting system.
In January 2000, FDA issued a 10-year strategic plan for regulation of dietary
supplements, which was a list of issues that the agency plans to address: safety,
labeling, boundaries among product categories, enforcement, science-based decision-
making, and stakeholder outreach. In December 2000, FDA announced it had
contracted with the National Academy of Sciences to study and provide a protocol
for the agency to use in reviewing supplement safety, as part of the 10-year plan. In
May 2002, FDA submitted to Congress a report on the cost of implementing the
strategic plan.
FDA’s regulation of supplements has been affected by Pearson v. Shalala, a
lawsuit filed by supplement manufacturers who challenged FDA’s general health
claims regulation of supplements and decision not to authorize four specific health
claims. The U.S. Court of Appeals held that the First Amendment does not permit
the agency to reject health claims that it determines to be potentially misleading,
unless FDA also reasonably determines that no disclaimer would eliminate the
potential deception. The court directed the agency to reconsider the four claims, and
FDA has since allowed two claims with qualifiers.
The Federal Trade Commission (FTC) issued an advertising guide for the
supplement industry in 1998. FTC addressed such issues as identifying claims and
interpreting their meaning, claim substantiation and related issues, to ensure its
enforcement efforts are as consistent as possible with the provisions of DSHEA and
its enabling laws.
On an international level, the U.N.’s Codex Alimentarius has initiated an effort
to provide standards and guidelines for vitamin and mineral products, which could
serve as a blueprint for countries wishing to adopt standards into their own laws. The
European Commission has proposed a directive for these same products which, if
adopted by its member countries, would affect supplements sold in those nations.
Numerous bills addressing dietary supplement regulation have been introduced
in the 107th Congress, although no further action has yet been taken on them.

Dietary Supplements: Legislative
and Regulatory Status
Passage of the Dietary Supplements Health and Education Act of 1994 (DSHEA
– P.L. 103-417) changed the regulatory framework for dietary supplements in the
United States. This report reviews the statutory changes that DSHEA contained and
the status and impact of their implementation by the federal agencies responsible,
particularly the Food and Drug Administration (FDA), within the Department of
Health and Human Services. Oversight of this legislation is likely to be an issue for
the 107th Congress.
Background
Following passage of the Nutrition Labeling and Education Act of 1990 (NLEA
– P.L. 101-535), the dietary supplement industry had a number of concerns about the
impact of NLEA implementation on supplement products. NLEA was the
comprehensive legislation requiring nutrition labeling on most food products,
including dietary supplements, and allowing nutrient content and health claims to be
made on food products, if certain relatively strict criteria were met. The law required
that information on specific nutrients be listed on food labels, regardless of whether
the nutrients were present.

While dietary supplements were regulated under the category of food, certain
NLEA provisions were likely to prove inappropriate or impractical for compliance
by supplement manufacturers. For example, the nutrition facts panel on the food
label required the listing of several nutrients rarely present in many supplements,
such as protein, fat, and carbohydrate, which would appear with zeros as the amount
contained in the products. This requirement would take up considerable space on the
relatively small supplement packages. At the same time, many nutrient and herbal
ingredients that were present would not be allowed to be listed on the nutrition facts
panel, because they were not on the government’s list of nutrients with recognized
consumption standards.
For claims, the strict criteria that the Act specified for either a nutrient content
or health claim to be made were expected to be virtually impossible for supplement
manufacturers to meet. Both types of claims required prior authorization by FDA,
through the use of a petition process, before they were allowed to appear in product
labeling. A health claim was allowed only if the agency determined that there was
significant scientific agreement based on the totality of the publicly available
evidence that a relationship exists between a nutrient and the risk of disease. NLEA
gave FDA the discretion to determine whether supplements should make health
claims under the same standard and procedure as conventional foods. The agency
determined that the same standard and procedure for making health claims should be

CRS-2
followed by both supplements and conventional foods, in part because many
substances for which claims would be made (i.e., vitamin C or calcium) were
contained in both types of products. However, there is a dearth of peer-reviewed
literature on the relationship between most supplement ingredients and health
conditions that might be used to support health claims.
Finally, NLEA listed 10 nutrient and disease relationships that FDA was to
review for possible authorization as health claims. Prior to passage of the Act, FDA
had proposed regulations for six of the 10 relationships listed in the Act for review.
The additional four relationships concerned supplement ingredients (folate, zinc,
omega-3 fatty acids, and antioxidants), which were added to the Act at the request
of the supplement industry. When FDA reviewed the 10 relationships, it initially
authorized six claims and has since authorized a total of 13 health claims for food
products. The agency initially did not authorize the four claims that were specific to
dietary supplements. Since then, the health claim for folate has been authorized,
along with a fortification requirement for folate in certain foods. The other three
claims continue to be reviewed by the agency (see discussion of the Pearson case
below).
In April 1991, then-FDA Commissioner Kessler convened an FDA Dietary
Supplement Task Force to examine the issues regarding dietary supplements and
develop a regulatory framework for these products that would best serve the public
health. The Task Force was established following FDA’s ban of the amino acid L-
Tryptophan, after nearly 1500 cases of illness and 39 deaths were allegedly caused
by use of this supplement product.1 The Task Force considered such issues as how
to ensure the safety of supplements, limit the potential for fraud, and ensure that the
marketing of supplements did not act as a disincentive for drug development.

In its final 1992 report to the Commissioner, the Task Force concluded that
safety should be the overriding concern for FDA in developing a regulatory
framework for this class of products.2 Specific recommendations included regulatory
changes for vitamin and minerals, amino acids and other products regulated as
supplements, and a number of cross-cutting issues such as: good manufacturing
practices, purity and identity, bioavailability, a consumer education program, a
compliance program for FDA district offices, compliance with all NLEA provisions,
partnerships with nongovernmental experts on scientific issues, an adverse event
reaction reporting system, action against misleading product names that implied
therapeutic properties, compliance with tamper-resistant and child-proof packaging,
coordination with the Federal Trade Commission, coordination with state agencies
to regulate supplements, and sharing FDA’s policies with the international
community. The report and a request for public comment was published in the

Federal Register,3 as an advanced notice of proposed rulemaking (ANPR). The
supplement industry raised concerns about the notice and the content of the Task
Force report.
At that time, the agency viewed supplement ingredients as unapproved and
present in products that were formulated and used as either drugs or food additives.
The supplement industry viewed the ingredients in their products as having had a
long history of use, similar to many food ingredients that were viewed as safe, and
therefore, not needing the type of safety testing required for food additives and drug
ingredients.
Congressional Action Since 1992
Ultimately the issues of nutrition labeling, claims and safety led to the passage
of DSHEA. In 1992, Congress passed the Dietary Supplement Act (P.L. 102-571),
which prohibited the Secretary of the Department of Health and Human Services
from implementing the provisions of NLEA that affected dietary supplements. The
only NLEA provision allowed to be implemented for supplements was the one
concerning authorized health claims. The 1992 Act also required that several reports
be prepared for Congress in preparation for subsequent legislation. These provisions
included a report prepared by FDA that reviewed the agency’s enforcement priorities
and practices for supplements;4 a report prepared by the General Accounting Office
that reviewed the management activities of FDA related to supplements, compared
to other products regulated by the agency;5 a report prepared by the Office of
Technology Assessment that reviewed the relationship between the regulatory
systems affecting the development and sale of dietary supplements and health
outcomes (uncompleted); and a report prepared by the Library of Congress that
reviewed the efforts of industrialized nations to regulate the manufacture and sale of
supplements and the effect of these regulatory efforts on human health.6 The
rationale for these reports was the perception that FDA had taken a disproportionate
amount of regulatory action against supplements compared to the other products that
it regulated, and that the regulation of supplements in other industrialized countries
was a seamless process that provided lessons that Congress might consider for
adoption.

Before the four reports requested in the 1992 Act were completed, however,
Congress passed DSHEA in 1994. The dietary supplement industry had, through
health foods stores and other retail outlets, promoted a successful grass-roots
campaign to get consumers to sign letters to Members of Congress seeking support
for dietary supplement legislation. In exchange, consumers were offered discounts
on supplement product purchases.7 The letters sought relief from the presumed threat
that FDA was going to ban certain supplements and require prescriptions for any
supplements left on the market. Some supplement retailers staged “black Mondays”
where they draped certain supplements in black and refused to sell them on a given
day in an effort to convince consumers to sign the form letters. Reportedly,
thousands of letters were received by each congressional office as a result of this
campaign. There is no evidence that FDA at that time, had plans either to ban most
dietary supplements or require prescriptions for their use, nor did the agency have the
authority or resources to implement such a policy.
While numerous bills on dietary supplement regulation were introduced in the
103rd Congress, bills introduced in the House (H.R.1709) and Senate (S.784) by
Congressman Bill Richardson and Senator Orrin Hatch, respectively, became the
focus of debate. There was considerable debate before the Act was passed by
unanimous consent in both chambers. In addition, a “Congressional Statement of
Agreement” entered into the Congressional Record for October 7, 1994, stated that
there would be no other reports or statements considered to be legislative history for
the bill,8 a decision which appears to have complicated implementation of the Act.
Provisions of the bill are addressed below in the section on implementation.
Implementation of DSHEA
The implementation of DSHEA has been a piecemeal process because of the
diverse provisions in the Act. Discussion in this section is in the chronological order
in which the promulgation of regulations for the provisions was completed, rather
than the order of the provisions in the Act. For more information on DSHEA, see
CRS Report 94-965, Dietary Supplement Health and Education Act, P.L. 103-417.
(Archived, available upon request from CRS).
Definitions. The Act defined a dietary supplement for the first time as
meaning a product (other than tobacco) intended to supplement the diet that contains
one or more of the following dietary ingredients: a vitamin, a mineral, an herb or
other botanical, an amino acid, a dietary substance for use by humans to supplement
the diet by increasing the total dietary intake, or a concentrate, metabolite,
constituent, extract, or combinations of any ingredient described above. The
definition further provides that a supplement is a product that is intended for human
ingestion as a tablet, capsule, powder, softgel, gelcap, liquid or some other form, is
not represented for use as a conventional food or as a sole item of a meal in the diet,

and must be labeled as a dietary supplement. A product marketed as a dietary
supplement cannot have been on the market as a new drug or biologic prior to being
marketed as a dietary supplement or food. Finally, the Act specifically excluded a
dietary supplement or its ingredients from the definition of a food additive.
Implementation. Because this section of DSHEA provided specific language
defining dietary supplement, FDA did not promulgate regulations. Instead the agency
adopted the language from the Act directly into its regulations.
Safety. Prior to DSHEA, FDA’s primary safety standard for a dietary
supplement was whether it failed the general food safety standard; i.e., that it bears
or contains any poisonous or deleterious substance which may render it injurious to
health. Under DSHEA, the safety standard itself was amended so that a supplement
or a dietary ingredient was to be considered unsafe, if it presented a significant or
unreasonable risk of illness or injury, under the conditions of use recommended or
suggested in labeling, or under ordinary conditions of use. A new dietary ingredient
for which there is inadequate information to provide assurance that it does not
present a significant or unreasonable risk of illness or injury would be considered
unsafe. In situations where the Secretary declares that an ingredient poses an
imminent hazard to public health or safety, the department must promptly follow the
declaration with a statement that either affirms or withdraws the declaration. The Act
placed the burden of proof of showing that a dietary supplement is unsafe on the U.S.
government, rather than on the manufacturers. Before the Secretary may report to the
Department of Justice that a supplement is unsafe for civil proceedings, the
individual against whom the proceeding will be initiated is to be given at least 10
days notice and opportunity to present both oral and written views before the
proceedings begin.
Implementation. Because this section of DSHEA provided specific language
on the safety standard, procedures for a regulatory action and the burden of proof of
safety for supplements, FDA did not promulgate regulations. Instead the agency
adopted the language from the Act directly into its regulations. Proving “a significant
and unreasonable risk to health” after it is on the market is considerably more
difficult than demonstrating that a product or its ingredients are safe in controlled
situations prior to marketing. Placing the burden of proof on the agency to
demonstrate that a marketed supplement is unsafe was a significant departure from
the policy for other FDA regulated products for which the manufacturer must
demonstrate safety before they are allowed on the market. Additionally, no resources
were provided to the agency to implement this provision. There is no requirement
for safety or efficacy testing of dietary supplement ingredients that have been on the
market since before DSHEA passage. Therefore, there is no database on which to
determine whether problems that seem to or are alleged to arise from the use of
certain supplements are a serious problem or anticipated side effect on which the
agency could base its determination that a supplement or ingredient may be unsafe.
Withdrawal of ANPR. DSHEA declared the June 18, 1993, ANPR null and
void, and of no force or effect. The Act required FDA to publish a notice to this
effect in the Federal Register. The ANPR notice had contained the FDA Task Force
on Dietary Supplements’ published report (mentioned above) along with the agency’s

CRS-6
request for comments on the issues raised in the report, particularly on the safety and
use of amino acids.
Implementation. FDA published a notice of the withdrawal of the ANPR and
the report on December 6, 1994.9
Ingredient and Nutrition Labeling. The Act required that a dietary
supplement product label provide the name and quantity of each ingredient, state that
it is a dietary supplement, and identify the portion of the plant that is the source of
an herbal ingredient. The product is required to meet the identity and strength
information that is stated on the label. Required nutrition information is to list first
the ingredients and the quantity present in significant amount for ingredients which
have a recognized recommendation for daily consumption, followed by ingredients
for which there is no recognized recommendation for intake. Labeling statements
that characterize the percentage level of a dietary ingredient contained in a
supplement are exempt from the regulations on percentage level when the Secretary
has not established a standard for the daily consumption of that ingredient. The Act
allowed this information to appear on supplement products upon enactment of the
law and it required all products to be so labeled by December 31, 1996.
Implementation. FDA published the proposed rules on several aspects of
nutrition and ingredient labeling for supplements on December 28, 1995.10 The
agency published final regulations on a number of issues for ingredient and nutrition
labeling of dietary supplements on September 23, 1997.11 These final rules addressed
statements of identity, nutrition labeling and ingredient labeling, label format,
requirements for nutrient content claims, health claims and statements of nutritional
support and definitions of high potency, and antioxidants for use in nutrient content
claims for both supplements and conventional foods. The final implementation date
was March 23, 1999.
Commission on Dietary Supplement Labels. DSHEA required that a
seven-member presidential commission be appointed to study and provide
recommendations for the regulation of label claims and statements for supplements,
including the use of literature provided at the point of sale and procedures for
evaluating claims. Commission members were to be individuals with expertise and
experience in the manufacture, regulation, distribution, and use of supplement
products, with at least three members qualified by scientific training and experience
to evaluate the benefits to health of supplement use. The Commission was given
administrative powers to conduct hearings, and secure necessary information from

federal agencies. It had 2 years to prepare and submit to the President and the
Congress a final report on the study, including any recommendations for legislation.
The Secretary of Health and Human Services had 90 days following issuance of the
report to publish a notice of proposed rulemaking on any recommendations for
changes contained in the final report of the Commission. Any rulemaking was to be
completed in 2 years after the issuance of the report.
The final report of the Commission on Dietary Supplement Labels was
published in November 1997.12 It contained recommendations in the form of
guidance on safety, labeling, NLEA claims on labeling, scope of statements of
nutritional support, notification letters and substantiation files for statements of
nutritional support, publications exempt from labeling regulations, and botanical
products. In addition, the Commission made recommendations regarding
information for consumers and health professionals, the need for industry expert
advice on key issues, future research, and the National Institutes of Health’s Office
of Dietary Supplements. One issue that had generated considerable discussion prior
to enactment of DSHEA was whether supplements should be required to use the
same standards and procedures as conventional foods to make health claims, and the
Commission concluded that supplements and conventional foods should use the
same standards and procedures. For additional information on the Commission on
Dietary Supplement Labels work and report, see CRS Report 97-937, Dietary
Supplements: Commission Report and FDA Regulation. (Archived, available upon
request from CRS)
Implementation. FDA published a notice on the Commission’s report on
April 29, 1998.13 The agency’s comments agreed in general with the Commission’s
report and indicated willingness to work with appropriate parties to implement the
Commission’s recommendations. However, FDA did indicate that agency funding
levels and statutory constraints prevented implementation of some recommendations.
Supplement Claims. DSHEA created a new provision that exempted from
labeling regulations any publication, including an article, book chapter, or official
abstract of a peer-reviewed scientific publication that appears in an article and was
prepared by the authors or editors of the publication which is reprinted in its entirety,
when used in connection with the sale of supplements to consumers. Such literature
is not to be false or misleading, cannot promote a particular brand of a supplement,
must be presented with such items on the same subject matter as to present a
balanced view of the available scientific information on a given supplement, is
displayed physically separate from the supplements in a retail establishment, and is
not appended to a supplement product by any means. This set of criteria does not
apply to books or other publications that are sold as part of the business of the retailer
or wholesaler. The Act places the burden of proof on the federal government to
establish that an article or other such matter is false or misleading.

Implementation. FDA did not promulgate rules related to the third party
literature available in retail operations that is exempt from labeling regulations.
There is neither a monitoring program, nor resources available for the agency to
initiate such a program. The requirement that balanced information be available is
difficult to enforce because, beyond scientific papers that are not generally consumer
friendly, materials that provide information on the benefits of using a particular
supplement or ingredient are generally written by those who are being paid to
promote the product and have no incentive for providing balanced information. The
difficulty in applying the requirements of this provision was considered by the
Commission on Dietary Supplements, which suggested proactive monitoring to
evaluate practices and determine the need for regulatory guidance.
Office of Dietary Supplements. The Act required that the Secretary
establish an Office of Dietary Supplements (ODS) within the National Institutes of
Health (NIH). The purpose of the Office is to explore the potential role of dietary
supplements as a significant part of the efforts to improve health care and promote
scientific study of the benefits of dietary supplements in maintaining health and
preventing chronic disease. ODS is to conduct and coordinate scientific research
within NIH relating to supplements and the extent to which their use can limit or
reduce the risk of chronic disease. The Office is to collect and compile the results
of scientific research relating to supplements, including from foreign sources and the
NIH Office of Alternative Medicine (OAM). ODS is to serve as the principal advisor
to the Department on issues related to supplements, including dietary intake
regulations, safety of supplements, claims for disease prevention, and labeling and
composition issues. Finally, the Office is to compile a database of scientific research
on supplements and individual nutrients, and coordinate funding for supplement
research within NIH. For FY1994, the Act authorized $5 million and permanently
authorized such sums as may be needed in subsequent fiscal years.
Implementation. The Office of Dietary Supplements (ODS) was established
in November 1995. It has developed and published a strategic plan,14 conducted
workshops and conferences on numerous dietary supplement ingredients, and
established an ad hoc advisors group. ODS has created the International
Bibliographic Information on Dietary Supplements (IBIDS) database and continues
development of the Computer Access to Research on Dietary Supplements (CARDS)
database. It began publishing an annual bibliography of significant advances in
dietary supplement research in 2000.15 In 1996, the Office announced its first
research enhancement awards and the number of awards has expanded annually. In
collaboration with the NIH National Center for Complementary and Alternative
Medicine (formerly OAM), ODS has established Centers for Dietary Supplement
research in four NIH-supported universities to study the health effects of botanicals.

Good Manufacturing Practices. The Act provided that a dietary
supplement not prepared, packed, or held under conditions that meet current good
manufacturing practice regulations, including expiration date labeling where
necessary, would be considered to be unsafe. The Secretary was allowed, by
regulation, to prescribe good manufacturing practices (gmps) for supplements. Such
rules were to be modeled after the current gmps for foods and were not to impose
standards for which there was no current and generally available analytical
methodology. No standard of current gmps was allowed to be imposed, unless that
standard was in a regulation that had been promulgated with opportunity for notice
and comment.
Implementation. FDA published an advanced notice of proposed rulemaking
on February 6 1997.16 This notice contained an industry–submitted document that
outlined suggested good manufacturing practices that were based primarily on current
food gmps, as well as some additional requirements that industry considered essential
to the manufacture of safe and properly labeled supplements. FDA requested
comments from all interested parties on the need for and specific requirements in
supplements gmps. In addition, the agency sought comments on a number of
additional issues: specific defect action levels, appropriate testing requirements,
certification standards for sanitation, need for quality control procedures, medical
followup for injury or illness reports, procedures for potential safety concerns,
specific controls for computer controlled operations, appropriateness of hazard
analysis and critical control points system, and specific segments of the supplement
industry. The deadline for comments was May 7, 1997. The numerous comments
received by FDA provided no clear consensus on the direction that the agency should
take. As a result, the agency formed a working group of the FDA Food Advisory
Committee to discuss and provide direction to resolve the outstanding questions.17
The proposed regulations on good manufacturing practices are currently under review
by the Bush Administration.
Statements of Nutritional Support. DSHEA allowed certain informational
messages to be made when the claim benefit related to: 1) a classical nutrient
deficiency and its prevalence in the United States, 2) describing the role of a
supplement ingredient to affect human structure or function, 3) a documented
mechanism of a supplement ingredient to affect human structure or function, or 4)
describing general well-being from consumption of a nutrient or dietary ingredient.
The manufacturer making such claims was required to have scientific evidence
substantiating that the claim was truthful and not misleading. In addition, the
statement was required to contain a disclaimer prominently displayed and in boldface
type stating that the statements had not been evaluated by FDA and that the product
was not intended to diagnose, treat, cure, or prevent any disease. The manufacturer
wishing to make this type of claim was required to notify FDA, no later than 30 days

after the first marketing of the supplement with this type of informational statement,

Implementation. FDA proposed rules on statements of nutritional support

recommended that the agency needed to provide specific guidelines for
manufacturers and distributors wishing to make such statements. The proposed
regulations addressed how to identify the types of statements that may be made
without prior FDA review of the effect of supplements on the structure and function
of the body, and how to distinguish these statements from drug claims.18 However,
the proposal received over 235,000 comments with the majority of concerns voiced
by the supplement industry that the proposed definition for disease was too narrow
to allow most claims to be made, while most comments from the health community
either supported the rule or believed that it was not restrictive enough. In response
to the significant questions raised in comments on the proposed rule, FDA convened
a public meeting on August 4, 1999 to address three major issues: the definition of
disease, claims related to natural states (such as pregnancy and menopause) and
implied structure/function claims.19 In the final rule published January 6, 2000, the
agency defined the types of supplement statements that can be made concerning
structure or function of the body, without prior authorization as health claims.20 It
also provided the criteria for determining when a supplement statement is a claim to
diagnose, cure, mitigate, treat or prevent disease, i.e., a drug claim which requires
prior approval. On February 22, 2001, FDA announced in the Federal Register that
it was seeking comments on the types of information that should be included in a
guidance document applying the regulations on structure/function statements made
for dietary supplements.21 A separate guidance document on the scientific evidence
required for the substantiation of claims is expected to be developed at a later date.
New Dietary Ingredients. DSHEA contained provisions for new dietary
ingredients that included any ingredient that was not marketed in the United States
before October 15, 1994 and excluded ingredients that were marketed in the United
States before DSHEA passed. A new dietary ingredient was allowed only if it had
been used in a food in a form that had not been chemically altered and there was a
history of use or other evidence of safety under the conditions of use recommended.
At least 75 days before it is introduced into interstate commerce, the manufacturer
or distributor of the supplement or ingredient is to provide the Secretary with

information, including any citation of published articles which led the manufacturer
or distributor to conclude that the ingredient will be expected to be safe. The
Secretary is to keep confidential any information provided for 90 days following its
receipt, before placing it on public display, while maintaining privacy of any
information that pertains to trade secrets or otherwise confidential, commercial
information. The Act created a mechanism for any person to file with the Secretary
a petition, proposing the issuance of an order prescribing the conditions under which
a new dietary ingredient, taken under its intended conditions of use, will be
reasonably expected to be safe. The Secretary has the responsibility to make a
decision on this type of petition within 180 days of its filing. The Secretary’s
decision is considered to be final agency action on the matter.
Implementation. FDA published the final rule on premarket notification for
a new dietary ingredient on September 23, 1997.22 The agency had proposed this rule
in September 1996. The regulation requires that certain information be submitted to
the agency as part of the notification of a new dietary ingredient, 75 days before it is
marketed. FDA will acknowledge receipt of the notification. The regulation became
effective on October 23, 1997. To date, the agency has reviewed and allowed about
70 new dietary ingredients to be used in supplement products. In February 2001,
FDA published a guidance document on agency notification for new dietary
ingredients in supplements.23
FDA Regulatory Actions on Specific Supplement Products
Since passage of DSHEA, FDA has issued alerts on several dietary supplements
to warn consumers about possible health and safety problems. Specific alerts have
been issued for Tiratricol (a potent thyroid hormone, November 21, 2000);24

Ephedrine alkaloids, used for weight loss and body building, is the dietary
supplement that has gotten most media attention since passage of DSHEA. FDA has
received numerous adverse event reports about its use, issued alerts (March 31,
2000), convened Food Advisory Committee meetings (October 11-12, 1995 and
August 27-28, 1996), held a public meeting (August 8, 2000), proposed regulations
(June 4, 1997), partially withdrawn regulations (April 3, 2000), and testified before
the House Committee on Governmental Reform (May 27, 1999) on this supplement.
No final action has been taken by FDA on ephedrine alkaloids. For additional
information, see CRS Report RL30750, Dietary Supplements: Ephedra.
Recent concern has been raised about mad cow disease and dietary supplements,
although so far there is no evidence that a problem exists with supplements
containing animal tissue. Because bovine brain tissue is used in certain supplements
intended to boost intelligence, sexual drive and energy, the potential exists for
transmission of the disease. Supplement manufacturers are not required to provide
label information on country of origin or animal tissues used in preparing the
products. Completion of the good manufacturing practices regulations could be
expected to improve confidence in the control over the source of ingredients used in
supplement products containing animal tissue. In November 2000, FDA published
a letter to reiterate public health and safety concerns to supplement manufacturers
making or importing supplements that contain specific bovine tissues.32
On January 30, 2001 FDA published a letter to manufacturers regarding
botanicals and other novel ingredients in conventional foods.33 The letter raised
general concerns about whether some herbal and other botanical ingredients that are
being added to conventional food may cause the food to be adulterated, because these
added ingredients are not being used in accordance with an approved food additive
regulation and may not be generally recognized as safe for their intended use.

In an effort to improve communication and assist consumers, FDA launched

supplements, tips on searching the web for supplement information, tips and to-do’s,
and selected references for further information.
FDA 10-Year Strategic Plan for Supplements
In January 2000, FDA issued a 10-year plan that outlines its strategy for the
regulation of dietary supplements.35 The stated goal is to have a science-based
regulatory program fully implementing DSHEA in place by the year 2010, to provide
consumers with a high level of confidence in the safety, composition and labeling of
dietary supplement products. Under safety issues, the agency has listed adverse event
reporting, good manufacturing practices, health hazard evaluations, a supplement
safety database, new dietary ingredients, voluntary submissions, and internet
surveillance. Labeling issues include resolution of Pearson v. Shalala (discussed
below), health claims petitions, database and substantiation for structure/function
claims, authoritative statements, consumer and marketplace labeling surveys,
publications, and small business exemptions. “Boundary” issues concern
structure/function claims, supplements vs. drugs, supplements vs. conventional
foods, botanicals, supplement exclusions, dual status, combination products, and
supplements vs. cosmetics. Enforcement activities will include an enforcement
strategy, capacity building, and Federal Trade Commission coordination. Under the
science-base, the agency has listed strengthening the science-base, research efforts,
dietary supplement ingredient reviews, leveraging resources, consumer and
marketplace research, regulatory oversight of human studies, adverse event report
monitoring system, claims, and an interagency clearinghouse. Finally, FDA indicates
its desire to enhance outreach through the use of advisory committees, additional
stakeholder outreach and communication.
In December 2000, FDA announced that it had contracted with the National
Academy of Sciences’ Institute of Medicine to study and provide an appropriate
protocol for the agency to use in reviewing the safety of dietary supplements, 36 as
outlined in the 10-year plan. The work is to include development of a proposed
framework for categorizing and prioritizing dietary supplement ingredients based on
safety issues, a process for developing a review system with specifications for
evaluating the safety and role in health of dietary supplement ingredients, and
development of at least six prototypes as examples of using the framework. The
framework is to include a methodology for evaluating the available peer-reviewed
literature with regard to the role of supplement ingredients in health, taking into

consideration methods other expert bodies have used to categorize and review issues

The contract is to be completed by September 29, 2002.
FDA’s Center for Food Safety and Applied Nutrition announced that it was
preparing a report that addressed a congressional inquiry about the amount of money
that the agency would need to implement the 10-year strategic plan issued in 2000.
Reportedly, the request would be for “tens of millions of dollars” for supplement
oversight, including adequate inspections of manufacturing operations.37 The agency
indicated its belief that the future of the enforcement program depends on adequate
funding in the long term. In a report transmitted to Congress on May 29, 2002, FDA
indicated that its base funding for dietary supplements in FY2001 was approximately
$6 million and 46 FTEs (year 2 of the plan).38 The agency estimates the initial
investment cost to implement the strategic plan would range from $20 million to $40
million for year 3, followed by an additional investment from $30 million to $55
million for year 4 and a final investment from $40 million to $65 million for year 5.
These estimates are reported in FY2002 current dollars.
FDA and the Pearson Case
Following the determination by the Commission on Dietary Supplement Labels
that the same standard and procedure for making health claims should be followed
for both supplements and conventional foods, FDA issued final regulations applying
the general requirements for health claims on supplements. Subsequently, lawsuits
were filed on behalf of a manufacturer that wished to make health claims for several
supplements, which were not authorized by the agency. In the case of Pearson v.
Shalala, the plaintiffs challenged FDA’s general health claims regulation for
supplements and the agency’s decision not to authorize health claims for four specific
substance and disease relationships. The claims that were not authorized were:
dietary fiber and cancer, antioxidant vitamins and cancer, omega-3 fatty acids and
coronary disease, and the comparative claim that .8 milligrams of folate in
supplement form is more effective in reducing the risk of neural tube defects than a
lower amount in conventional food form.
In 1998, a federal district court ruled for FDA in all respects. However, the U.S.
Court of Appeals for the D.C. Circuit reversed the lower court’s decision, holding
that the First Amendment does not permit the agency to reject health claims that it
determines to be potentially misleading, unless FDA also reasonably determines that
no disclaimer would eliminate the potential deception. The court invalidated the
FDA regulations that prohibited authorization of the four health claims and directed
the agency to reconsider the four claims. Further, the court held that the agency was
required under the Administrative Procedure Act to clarify the “significant scientific
agreement”(SSA) standard for authorizing claims, either by issuing a regulatory

definition, or defining it on a case-by-case basis. On March 1, 1999, the government
filed a petition for reconsideration by the full Court of Appeals, but the petition was
denied on April 2, 1999.
On December 1, 1999, FDA published a notice on its strategy for implementing
the Pearson court decision.39 The components of the plan included: a) updating the
scientific evidence on the four claims in the case, b) issuing guidance clarifying the
SSA standard,40 c) convening a public meeting to solicit input on changes to FDA’s
general health claims rules for supplements that were warranted in light of the
Pearson decision,41 d) initiating rulemaking to reconsider the general health claims
rules in light of the Pearson decision, and e) conducting rulemaking on the four
Pearson health claims. Since then, the agency has completed the first three
components of the Pearson implementation strategy and issued an interim
enforcement strategy for supplement health claims.
Subsequent to that notice, FDA released letters regarding the four Pearson
health claims. In each case, the agency has provided documentation based on the
available scientific evidence that supports its decisions concerning the claims. FDA
has continued to deny the claim for fiber and colorectal cancer, which the scientific
evidence does not support and stated that use of a qualifier would be misleading.42
Likewise, the agency continues to deny the comparative claim for folic acid and
neural tube defects which also is not supported by scientific evidence and finds the
use of a qualifier would be not remedy the statement’s untruthfulness.43 FDA
initially allowed the claim for omega-3 fatty acids and coronary heart disease, with
a qualifier, 44 but subsequently changed its position to allow a disclaimer that the
evidence is inconclusive.45 The agency also has allowed the claim for folic acid,

its review of the petition for a health claim for antioxidants and cancer, and
concluded that there is no significant scientific agreement for a relationship between

reduced risk of cancer is inherently misleading and cannot be made non-misleading
with a disclaimer or other qualifying language.47
Inspector General’s Report on Dietary Supplements
In April 2001, the HHS Inspector General (IG) released its findings and
recommendations on FDA’s adverse events reporting system for dietary supplements
and its effectiveness as a consumer protection tool.48 The report finds that FDA’s
adverse event reports (AERs) system detects relatively few adverse events due to
underreporting, and has difficulty generating signals of possible public health
concerns because of the limited information for the AERs that are collected. In
addition, FDA lacks vital information to adequately assess signals of possible public
health concerns generated by the AERs system, which is limited by a lack of clinical
information on both safety studies and consumer use. The IG determined that as a
result of the dearth of information in all aspects of the AERs system, FDA rarely
takes safety actions.
The IG recommendations included facilitating greater detection of adverse
events by requiring supplement manufacturers to report serious adverse events to
FDA. The IG also said the agency should obtain the Poison Control Centers AERs
for supplements, and health professionals and consumers need to be better informed
about the AERs system for supplements. A second recommendation was to obtain
more information on AERs in order to generate stronger signals of public health
concerns by educating health professionals about the importance of including medical
information in AERs, requiring supplement manufacturers and their products to be
registered with FDA, notify manufacturers when FDA receives a serious AER,
emphasize to health professionals and consumers the importance of providing a way
to identify the alleged injured party, and develop a new computer database to track
and analyze AERs.
In order to obtain vital information to adequately assess signals generated by the
AERs system, the report recommends that FDA issue guidance on the type of safety

Federal Trade Commission and Supplement Advertising
Although DSHEA applied to the labeling of dietary supplements, which is
regulated by FDA, the Federal Trade Commission (FTC) issued an advertising guide
for the dietary supplement industry following its passage.49 FDA has responsibility
for claims in product labeling and FTC has responsibility for claims in product
advertising. The two agencies work closely together under a liaison agreement to
ensure that their enforcement efforts are consistent to the fullest extent possible under
their respective laws. In the advertising guide, FTC has addressed such issues as
identifying claims and interpreting meaning conveyed in the advertising message,
substantiating claims and other issues (testimonials and expert endorsements,
traditional use, use of the DSHEA disclaimer, and third party literature).
Since release of this 1998 Supplement Advertising Guide, FTC reports having
stepped up its enforcement activities and that 17 cases in which the Commission took
action have been settled.50 Included were claims for remedies for serious diseases
that were not supported by competent and reliable scientific substantiation, safety
problems without warning statements, and a few cases in which monetary relief was
required. Some serious conditions for which claims were made included cancer,
AIDS, arthritis, attention deficit/hyperactivity disorder (ADHD), and weight loss. An
additional 20 active investigations involving supplement products are underway,
focusing on similar enforcement concerns: safety, lack of scientific support for
claims, widespread national advertising claims of unproven products, and internet
fraud.
Codex Alimentarius and European Union Activities
Several efforts are underway to develop international guidelines for supplements
containing vitamins and minerals. The Codex Alimentarius is an international
intergovernmental body responsible for the implementation of the United Nation’s
Joint Food and Agriculture Organization/World Health Organization’s Food
Standards Program. Its committees meet on a regular basis to draft standards and
guidelines that affect various aspects of food trade. The Committee on Nutrition and
Foods for Special Dietary Uses is responsible for determining the need to develop

standards and guidelines on the nutritional quality of foods, including supplements.
At a 1995 meeting the Committee voted to draft proposed guidelines on vitamins and
mineral products, addressing recommendations for minimum and maximum dosages,
approved and prohibited ingredients, and labeling claims. At a 1996 meeting,
Committee members reached agreement on most issues. However, unresolved was
the method to use in setting safe upper dosage levels for vitamins and minerals, in
part because different methods result in different levels. After 5 years of debate, this
issue remains unresolved, although the Committee continues to work toward
completing the guidelines on vitamins and minerals. At the November 2001 meeting,
Committee members proposed a preamble to the document on guidelines for
vitamins and mineral products. The Committee is seeking comments on the
preamble and other changes to the guidelines until the next session meeting
scheduled for Berlin in November 2002.
The Codex draft document on guidelines for vitamins and minerals reflects the
concern of several governments about the current level of regulation of supplements
in some countries. If finalized, the document would represent agreement of the
signatory nations that these products should be regulated at some baseline level. The
Codex document would not be binding on any member country, unless the guidelines
were adopted into the laws of that country. Completion of the Codex document will
not dictate the sale, availability or content of supplements marketed in the United
States, unless its provisions are enacted into law by Congress. The adoption of the
guidelines into law by other countries could affect the export of U.S.-produced
supplements to those countries, if U.S. manufactured supplements do not meet the
standards set by the regulations of those countries. For further information on this
issue, see CRS Report 98-500, Dietary Supplements: FDA Reform and Codex.
The European Commission announced in May 2000 that it had adopted a
proposal for a directive on food supplements setting out harmonized rules for the sale
of vitamins and minerals as dietary supplements. The objectives are to set a general
framework and safety rules for vitamins and minerals in the European Union, and to
provide consumers with detailed information through labeling on recommended daily
consumption, warnings on side effects from excessive use, and a statement that the
pills are not a substitute for a varied diet. Health claims are prohibited and products
packaged in a way that resembles a pharmaceutical product must carry the statement
that “this is not a medicinal product.” The proposal contains a positive list of
chemical substances authorized for use in the production of vitamins and minerals.
The proposal for a directive on food supplements is part of a package of
measures being considered on food safety. The European Parliament and Council of
Ministers have to agree for this directive to take effect. If adopted, the directive
would become effective on May 31, 2002, allowing the marketing of products
complying with its provisions as of June 2002 and prohibiting the marketing of
products that do not respect its rules no later than June 2004. It is unclear at this time
what impact this directive, if adopted, will have on U.S.-manufactured vitamin and
mineral products. The final document was expected to be issued in 2001. However,
several EU member countries have blocked completion of the current proposals. The
disagreement, not surprisingly, concerns how to set a safe upper level of the vitamins
and minerals, the subject of protracted debate in the Codex committee trying to
address the same issue.

Bills in the 107th Congress
A number of bills concerned with dietary supplements have been introduced in
the 107th Congress. Addressed in this report are supplement bills that directly
concern supplement regulation and tax exemptions. Several additional bills
concerned with ephedra, allowing supplements to be purchased with food stamps,
general FDA appropriations to enhance enforcement, access to medical treatment,
bioterrorism and importation issues will not be addressed in this report because they
are the subject of other CRS publications that address supplements among the other
products regulated by FDA.
Senator Harkin and Representative Burton introduced the Dietary Supplement
Tax Fairness Act of 2001 (S. 1330 and H.R. 3475). The bills would amend the
Internal Revenue Code of 1986 to provide that amounts paid for foods for special
dietary use, dietary supplements or medical foods be treated as medical expenses. It
was referred to the Senate Committee on Finance and the House Committee on Ways
and Means.
The Ginseng Truth in Labeling Act of 2001 (S. 1664 and H.R. 3329) was
introduced by Senator Feingold and Congressman Obey. The bills would require the
country of origin labeling of the raw agricultural form of ginseng by requiring
disclosure in a particular manner and leveling fines for failure to disclose this
information. These bills were referred to the Senate Committees on Agriculture,
Nutrition and Forestry, Health, Education, Labor and Pensions, and the House
Committees on Agriculture, and Energy and Commerce.
The Foods are not Drugs Act (H.R. 2265) was introduced on June 21, 2001 by
Representative Paul. The bill would allow consumers greater access to information
regarding the health benefits of food and dietary supplements, by allowing foods and
dietary supplements to make claims for use in the diagnosis, cure, mitigation,
treatment or prevention of disease in man or animals. This bill was referred to the
House Committee on Energy and Commerce.
On October 9, 2001 Representative Davis introduced the Dietary Supplement
Information Act (H.R. 3065). The bill would require that manufacturers of dietary
supplements register with FDA and submit reports on adverse experiences regarding
their supplement products to the agency, provide for inspection authority for records
on dietary supplements, require labeling of supplements with a toll-free telephone
number and internet address, and set a deadline for the publication of proposed rules
for good manufacturing practices for supplements. It was referred to the House
Committee on Energy and Commerce.
In February 2002, Representative Paul introduced a bill to amend FDCA to
establish a system independent of FDA for the review of health claims, to define
health claims and for other purposes. The Health Information Independence Act of
2002 would extend certain food and nutrition labeling requirements to dietary
supplements and would require nutrition labels to include the relationship of a
nutrient to the prevention, treatment or cure of a disease. The Secretary of HHS
would be required to solicit independent scientific reviewers from the academic
community to review, evaluate and make recommendations on a particular nutrient-

CRS-20
disease association based on the available scientific evidence, excluding health
claims only if they are unsupported by credible scientific evidence and no disclaimer
could eliminate potentially misleading connotations. Reviewers’ recommendations
would be binding on the Secretary and reviewable only by the U.S. Court of Appeals
of D.C. The bill would require the cost of the reviews to be offset against the
operating budget of the Department of Health and Human Services. It was referred
to the House Committee on Energy and Commerce.
Interest in the 107th Congress
Oversight hearings on DSHEA were expected to be an issue taken up by both
chambers during the 107th Congress, although to date only one hearing has been
held. On March 20, 2001 the House Committee on Government Reform held a
hearing on the current status of DSHEA implementation with particular attention to
issues concerning the Codex Alimentarius and the development of supplement-
specific GMPs. The nongovernmental and FDA witnesses all agreed that additional
funding and other resources are needed for the agency to improve its enforcement
activities.
A bipartisan congressional caucus on Complimentary and Alternative Medicine,
and Natural Foods was established in the 107th Congress. It was designed to educate
Members on evolving policy and regulatory issues on alternative health practices and
natural foods through seminars and other events. The inclusion of natural foods as
a main focus of the caucus indicates the expanding interest in the use of such
products as vitamins, minerals, and botanicals to improve or sustain health. Concern
that FDA lacks authority and funding to adequately oversee such products has led
several trade associations and organizations to pursue private certification and review
approaches for these products.
Considerable attention has been raised recently on the issue of FDA funding and
adequate appropriations to implement its statutory mandates and other congressional
directives on the regulation of dietary supplements. FDA’s release of the report to
Congress estimating the funding for implementation of the strategic plan for
supplement regulation provides additional information to be considered in future
appropriations for supplement enforcement. The 2000 House hearing illicited a
unanimous response from witnesses on increased appropriations for enforcement
activities for dietary supplements. The Inspector General’s report provides
considerable discussion on the effectiveness of the current supplement adverse events
reporting system and makes recommendations on how to improve its usefulness,
including adequate resources. Congress may wish to consider what seems to be a
general concern from both the agency and others that FDA needs adequate funding
in the future, if DSHEA is to be fully implemented.
