17. Dietary Supplement and the Law: DSHEA • The Dietary Supplement Health and Education Act (DSHEA) was passed in 1994 by Congress to: • Limit obstacles to marketing/promoting DS • Provide for wide availability of DS to consumers • Enhance information available to consumers • Food and Drug Administration (FDA) given regulatory control over DS

18. Dietary Supplement Health and Education Act 1994 Allows for product labeling claims as long as it does not diagnose, prevent, treat or cure a specific disease While the statements must be truthful and not misleading, there is not a review/approval process by the FDA

19. Dietary Supplement Health and Education Act 1994 The manufacturer is responsible to ensure the product is safe Manufacturers/distributors are not required to record, investigate or forward to the FDA any reports of injuries or illnesses that may be related to use of their product

20. General Concerns • Without regulatory control there is a buyer beware market • Dietary supplement advertisements can be misleading and deceptive • Claims of effectiveness may not be credible • The concentration and quality of active ingredients can differ from product to product • Dietary supplements may adversely interact with each other as well as prescription medications. • Dietary supplements are often utilized as a short cut to optimal nutritional practices.

22. Multivitamin/Mineral Supplements Multivitamins can be useful for filling in the gaps in your diet. A daily multivitamin/mineral supplement providing < 100% of the RDI for any one nutrient is reasonable for individuals who fail to consume a balanced diet Avoid “megadose” products supplying 1000% of the RDI for Vitamins A, E, other fat-soluble vitamins, and beta-carotene
