Dietary Supplements • Products intended to supplement the diet that contain at least one dietary ingredient to include: • Vitamins • Minerals • Herbs or other botanicals • Amino acids • and substances such as enzymes
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
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
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
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.
Analysis of Dietary Supplements • Study of 12 brands • 11/12 contained <90% or >110% of amount listed on label • 5/12 contained at least one ingredient not listed on label • 2/12 were missing at least one ingredient listed on label • Study of 240 supplements • 18.8% contained steroids or pro-hormones not listed on label
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

Other Claims • Health-maintenance claims: • “Maintains healthy circular system” • Non-disease claims: • “helps you relax” • “for muscle enhancement” • Cannot make maintenance claims about osteoporosis and other “serious diseases” • Can make health claim about relationship between a product or substance and the disease if approved
Key Points Manufacturers of DS do not have to demonstrate safety or effectiveness Using DS may jeopardize mission success Do your homework before using DS to ensure safety Only high quality products with USP certification labels should be used Combining and stacking DS increase the potential for unsafe side effects
