Guidance for Industry
Questions and Answers Regarding the Labeling of Dietary Supplements as Required by the Dietary Supplement and
Nonprescription Drug Consumer Protection Act
This guidance represents the Food and Drug Administration's (FDA's) current thinking on this topic. It does not create or
confer any rights for or on any person and does not operate to bind FDA or the public. You can use an alternative approach if
such approach satisfies the requirements of the applicable statute and regulations. If you wish to discuss an alternative
approach, contact the FDA staff responsible for implementing this guidance. If you cannot identify the appropriate FDA staff,
call the telephone number listed on the title page of this document.

I. Introduction
This document provides guidance to the dietary supplement industry for complying with the labeling requirements prescribed for
dietary supplement manufacturers, packers, and distributors by the Dietary Supplement and Nonprescription Drug Consumer
Protection Act (Pub. L. 109-462, 120 Stat. 3469). The guidance covers the following topics:
(1) what "domestic address" means for purposes of the dietary supplement labeling requirements in section 403(y) of the
Federal Food, Drug, and Cosmetic Act (FD&C Act);
(2) FDA's recommendation for the use of an introductory statement before the domestic address or phone number that is
required to appear on the product label under section 403(y);
(3) when FDA intends to begin enforcing the labeling requirements of section 403(y).
FDA's guidance documents, including this document, do not establish legally enforceable responsibilities. Instead, guidance
documents describe the Agency's current thinking on a topic and should be viewed only as recommendations, unless specific
regulatory or statutory requirements are cited. The use of the word should in Agency guidance means that something is suggested
or recommended, but not required.

II. Background
On December 22, 2006, the President signed into law the Dietary Supplement and Nonprescription Drug Consumer Protection Act.
This law amends the FD&C Act with respect to adverse event reporting and recordkeeping for dietary supplements and nonprescription drugs marketed without an approved application. This guidance document contains questions and answers relating to
the new labeling requirements for dietary supplements under the Dietary Supplement and Nonprescription Drug Consumer
Protection Act.

III. Questions and Answers

Dietary Supplements > Guidance for Industry: Questions and Answers Regarding the Lab... Page 2 of 3

What information must be included on the label of a dietary supplement to enable consumers to report serious
adverse events associated with the use of the dietary supplement?
Section 403(y) of the FD&C Act (21 U.S.C. 343(y)) requires the label of a dietary supplement being marketed in the United
States to include "a domestic address or domestic phone number through which the responsible person … may receive a
report of a serious adverse event with such dietary supplement." If the label does not include the required domestic address
or phone number, the dietary supplement is misbranded.
When the responsible person chooses to provide a domestic address (rather than a phone number) for adverse event
reporting, FDA concludes that the statute requires the product label to bear a full U.S. mailing address that includes the street
address or P.O. box, city, state, and zip code of the responsible person (i.e., the manufacturer, packer, distributor, or retailer
identified on the dietary supplement label). FDA finds that Congress's use of the term "domestic address" in section 403(y) is
a clear and unambiguous directive that dietary supplement labels include all information necessary to enable a serious
adverse event report to reach the responsible person. This reading of section 403(y) is supported by dictionary definitions of
"address," which include "the indication of destination, as on mail or parcels" and "the location at which a person or an
organization may be reached" (Ref. 1). Indeed, an address does not serve its intended purpose unless it includes all the
information necessary to enable mail to reach its destination.
Similarly, when the responsible person chooses to provide a domestic phone number for adverse event reporting, FDA
concludes that the statute requires the phone number on the product label to include an area code (e.g., a toll-free area code
such as 800 or a local area code such as 301). Without the area code, the phone number is incomplete and does not serve its
intended purpose of enabling the consumer to contact the responsible person to report a serious adverse event.
Congress's use of the phrase "through which the responsible person … may receive a report" to modify "domestic address or
domestic phone number" further supports FDA's conclusion that "domestic address or domestic phone number" means a
complete address or phone number (see section 403(y) of the FD&C Act (21 U.S.C. 343(y))). This phrase shows Congress's
intent that the domestic address or phone number on the label be sufficient to ensure that the responsible person will actually
receive the serious adverse event reports that consumers submit. If the address provided on the product label for adverse
event reporting is incomplete (e.g., no street address or P.O. box), some of the serious adverse event reports that are
submitted to the responsible person by mail likely will not be received. In addition, when consumers notice the incomplete
address, they may decide not to submit a report to the responsible person because they believe it will not be received.
Similarly, a phone number without an area code would be useless to consumers except for those who happen to be in the
same area code as the responsible person.
The use of the term "domestic address" in section 403(y) contrasts with Congress's use of a different term, "place of
business," in section 403(e) of the FD&C Act (21 U.S.C. 343(e)). Section 403(e) provides that foods, including dietary
supplements, are misbranded unless the product label bears the name and place of business of the manufacturer, packer, or
distributor of the food. FDA's regulations interpret "place of business" to require only the firm's city, state, and zip code to
appear on the product label, as long as the firm's street address is listed in a current telephone directory or other city
directory (21 C.F.R. 101.5(d)). The use of the term "domestic address" in section 403(y) demonstrates Congress's intent to
require the responsible person's full address, including the street address or P.O. box, to appear on dietary supplement labels
when the responsible person has opted to receive serious adverse event reports by mail. If Congress had considered the less
complete address already required under the "place of business" labeling regulation to be adequate for serious adverse event
reporting, there would have been no need to impose a new, more specific requirement in section 403(y) for the responsible
person's "domestic address" to appear on dietary supplement labels.
2. Should the label of a dietary supplement also include language indicating that the purpose of the domestic
address or phone number is to report serious adverse events associated with use of the dietary supplement?
Although section 403(y) does not require a label to include anything other than a domestic address or domestic phone
number for the responsible person, FDA recommends that the label also bear a clear, prominent statement informing
consumers that they may report serious adverse events to the domestic address or domestic phone number on the label.
FDA would have no objection to a firm's combining the recommended statement with language informing consumers that the
domestic address or phone number on the label may also be used for other purposes, as long as the information provided is
not false or misleading. The responsible person can also clarify that a doctor should be called for medical advice. For example,
a multi-purpose label statement might be "You should call your doctor for medical advice about serious adverse events. To
report a serious adverse event or obtain product information, contact…" or other similar language.
Responsible persons may also provide on the product label an email address or website to which reports may be made,
provided that such email address or website is in addition to the domestic phone number or domestic address required by
Section 403(y) of the FD&C Act (21 U.S.C. 343(y)).
3. When do the labeling requirements in section 403(y) become effective?
Under section 3(d)(2) of the Dietary Supplement and Nonprescription Drug Consumer Protection Act, the labeling
requirements of section 403(y) of the FD&C Act apply to all dietary supplements labeled on or after December 22, 2007.
Therefore, these labeling requirements are already in effect. However, FDA intends to exercise enforcement discretion for the
new labeling requirements until September 30, 2010.
Congress provided one year after the Dietary Supplement and Nonprescription Drug Consumer Protection Act was signed into
law on December 22, 2006, for affected firms to comply with its new requirements. However, due to competing priorities,
FDA was not able to consider, develop and finalize guidance on the labeling requirements of Section 403(y) until now. As a
result, firms did not have the benefit of FDA's guidance on how to comply with the new labeling requirements when the
requirements went into effect. Although the December 2008 revised draft guidance notified industry that the agency intended
to exercise enforcement discretion for the new labeling requirements until January 1, 2010, this final guidance sets forth
FDA's intention to exercise enforcement discretion for the new labeling requirements for dietary supplements labeled on or
after September 30, 2010, approximately one year after this final guidance issues. This period of enforcement discretion
should be adequate to enable all firms to meet the new labeling requirements for dietary supplements. FDA intends to begin
enforcing the requirements of 403(y) for dietary supplements labeled on or after September 30, 2010.
