title: What makes consumers think dietary supplements are safe and effective? The role of disclaimers and FDA approval.
abstract: OBJECTIVE
  The present study was designed to examine the effect of the Food and Drug Administration's (FDA) regulatory framework on beliefs about the safety and effectiveness of a dietary supplement.
  
  
  METHODS
  An experimental study was conducted with a sample of college students (N = 262). Participants read a description of a dietary supplement, and the experimental manipulations were embedded in the product description.
  
  
  METHODS
  Primary measures of interest included overall knowledge of the FDA's role in regulating dietary supplements and safety and effectiveness ratings of the dietary supplement.
  
  
  RESULTS
  Results demonstrated that individuals were not very knowledgeable about the FDA's role in regulating dietary supplements. Making participants explicitly aware that the FDA did not approve a dietary supplement lowered safety ratings of the supplement but had no influence on effectiveness ratings. The opposite results were obtained for a structure-function disclaimer in which the presence of the disclaimer lowered effectiveness ratings of the supplement but did not affect safety ratings.
  
  
  CONCLUSIONS
  Results highlight the importance of educating individuals about the FDA's role in regulating dietary supplements.
