In July of 2005, the Codex Alimentarius Commission adopted the Guidelines for Vitamin and Mineral Food Supplements. Some U.S. citizens have expressed concern that these Guidelines will restrict consumers' access to the wide range of vitamin and mineral supplements of varying potencies legally sold in the United States. Others are concerned that the Guidelines will limit the amount and type of information on the labels of dietary supplements sold in the United States. Still others believe that the Guidelines will require dietary supplements to be sold as drugs in the United States.
We hope the responses below help you understand why the Codex Guidelines for Vitamin and Mineral Food Supplements will not restrict U.S. consumers' access to vitamin and mineral supplements or impose any restrictions that go beyond those established by U.S. law. We also hope the responses help explain why the U.S. participates in the Codex process and how you can keep abreast of Codex activities.
The Codex Alimentarius Commission, or Codex, was created in 1963 by two U.N. organizations, the Food and Agriculture Organization and the World Health Organization. Its main purpose is to protect the health of consumers and to ensure fair practices in international trade in food through the development of food standards, codes of practice, guidelines and other recommendations. Codex standards and guidelines are developed by committees, which are open to all member countries. Member countries review and provide comments on Codex standards and related texts at several stages in the development process. In the United States, public meetings are held to receive comments on Codex drafts and comments are invited from all interested parties (See U.S. Codex Office web site). Codex standards and related texts are voluntary; member countries are not bound by or required to adopt them.

In the early 1990's, the Codex Committee on Nutrition and Foods for Special Dietary Uses (CCNFSDU) began discussions on guidelines for vitamin and mineral supplements. This Committee is responsible for studying nutritional issues referred by the Codex Alimentarius Commission; drafting provisions, as appropriate, on the nutritional aspects of all foods; and developing standards, guidelines, or related texts for foods for special dietary uses. Germany is the host government for the Committee, which has met either every year or every other year since 1966.
At the 26 th CCNFSDU session (Bonn, November 1-5, 2004), the Committee completed work on Draft Guidelines for Vitamin and Mineral Food Supplements and submitted them for adoption by the Codex Alimentarius Commission (CAC). The Guidelines were adopted at the 28 th CAC Session that was held in Rome on July 4-9, 2005.
The Guidelines apply only to supplements that contain vitamins and/or minerals, where these products are regulated as foods.
The Guidelines address the composition of vitamin and mineral supplements, including the safety, purity, and bioavailability of the sources of vitamins and minerals.
The Guidelines do not specify upper limits for vitamins and minerals in supplements. Instead, they provide criteria for establishing maximum amounts of vitamins and minerals per daily portion of supplement consumed, as recommended by the manufacturer. The criteria specify that maximum amounts should be established by scientific risk assessment based on generally accepted scientific data and taking into consideration, as appropriate, the varying degrees of sensitivity of different consumer groups.
The Guidelines also address the packaging and labeling of vitamin and mineral supplements.
We encourage you to read the complete text of the Guidelines, which is found in Appendix II of the report of the most recent session of the CCNFSDU. See ALINORM 5/28/26 on the Codex website (see "Reports" under the "Meetings and Events" pull down menu).
The U.S. supports consumer choice and access to dietary supplements that are safe and labeled in a truthful and non-misleading manner. The Dietary Supplement Health and Education Act of 1994 (DSHEA) ensures that a broad array of dietary supplements are available to U.S. consumers. The Codex Guidelines for Vitamin and Mineral Food Supplements do not, in any way, affect the availability of supplement products to U.S. consumers. On the contrary, the absence of science-based Codex guidelines could adversely affect the ability of U.S. manufacturers to compete in the international marketplace.
Some consumers mistakenly believe that with the adoption of the Guidelines on Vitamin and Mineral Food Supplements, the U.S. is required to automatically change its laws and regulations to comply with the international standard. Some have expressed concerns that the World Trade Organization (WTO) and its trade dispute settlement panels may place pressure on the U.S. to change its laws because of international trade agreements such as the Agreement on the Application of Sanitary and Phytosanitary Measures (SPS Agreement), which references Codex as the international organization for food safety standards.
We see no basis for these concerns. First, the DSHEA covers a much broader range of dietary supplements than the vitamin and mineral supplements that are the subject of the Codex Guidelines. Moreover, for supplements covered by these Guidelines, we note the following:
Further, there is no basis for the concern that the Codex Guidelines on Vitamin and Mineral Food Supplements would require dietary supplements be sold as prescription drugs in the United States. First, there is nothing in the Guidelines that suggests that supplements be sold as drugs requiring a prescription. Second, U.S. regulatory agencies are bound by the laws established by Congress, not by Codex standards. Third, because of our generally less restrictive standards, it is unlikely that the trade dispute would be brought against the U.S.
In summary, U.S. consumers' access to a broad array of dietary supplements under DSHEA would not be changed in any way by Codex's adoption of guidelines on vitamin and mineral food supplements.
All Codex standards and related texts are voluntary, and vitamin and mineral food supplement products sold in the U.S. would not be required to comply with provisions that are more restrictive than U.S. law (i.e., DSHEA).
Our participation in the Codex process is important to encourage the development of guidelines on vitamin and mineral supplements that are based on sound science and not on arbitrary criteria. For example, encouraging the use of science-based risk assessment for determining the maximum levels of vitamins and minerals in supplements reduces the chance that arbitrary standards will be used for determining maximum levels.

The appendices to the committee reports provide the latest draft versions following a committee meeting of some of the Codex standards that are being developed or revised by the Committee.
