1 DIETARY SUPPLEMENT HEALTH AND EDUCATION ACT OF 1994 DEFINITION OF DIETARY SUPPLEMENT is a product (other than tobacco) that is intended to supplement the diet that bears or 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 man to supplement the diet by increasing the total daily intake, or a concentrate, metabolite, constituent, extract, or combinations of these ingredients. is intended for ingestion in pill, capsule, tablet, or liquid form. is not represented for use as a conventional food or as the sole item of a meal or diet. is labeled as a "dietary supplement." includes products such as an approved new drug, certified antibiotic, or licensed biologic that was marketed as a dietary supplement or food before approval, certification, or license (unless the Secretary of Health and Human Services waives this provision).

2 SAFETY Under DSHEA a dietary supplement is adulterated if it or one of its ingredients presents "a significant or unreasonable risk of illness or injury" when used as directed on the label, or under normal conditions of use (if there are no directions). A dietary supplement that contains a new dietary ingredient (i.e., an ingredient not marketed for dietary supplement use in the U.S. prior to October 15, 1994) may be adulterated when there is inadequate information to provide reasonable assurance that the ingredient will not present a significant or unreasonable risk of illness or injury The Secretary of HHS may also declare that a dietary supplement or dietary ingredient poses an imminent hazard to public health or safety

3 NUTRITIONAL SUPPORT STATEMENTS Claims may not be made about the use of a dietary supplement to diagnose, prevent, mitigate, treat, or cure a specific disease (For example, a product may not carry the claim "cures cancer" or "treats arthritis." ) Appropriate health claims authorized by FDA--such as the claim linking folic acid and reduce risk of neural tube birth defects and the claim that calcium may reduce the risk of osteoporosis--may be made in supplement labeling if the product qualifies to bear the claim. Manufacturers may describe the supplement's effects on "structure or function" of the body or the "well-being" achieved by consuming the dietary ingredient. To use these claims, manufacturers must have substantiation that the statements are truthful and not misleading and the product label must bear the statement "This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease."
