| a. | any standards addressing safety merely regulate labeling and manufacturing processes. |
| b. | manufacturers must provide the FDA with efficacy claims prior to marketing their supplements. |
| c. | the DSHEA requires labeling that prohibits claims of treatment of specific diseases or conditions. |
| d. | the FDA must approve dietary supplements prior to marketing them in the United States. |
ANS: A
Dietary supplements are regulated under the Dietary Supplement Health and Education Act of 1994 (DSHEA). This special category exempts them from the scrutiny applied to foods and drugs. A set of standards issued by the FDA in 2007 is designed to ensure that supplements are devoid of adulterants, contaminants, and impurities and that labels reflect the contents—these standards do not ensure safety and efficacy. Efficacy claims must be provided but are not required to prove these claims; a claim to efficacy does not guarantee safety. Regulations prohibiting disease-specific claims do not ensure safety. The FDA does not approve dietary supplements prior to marketing.
