Explain some of the differences between the regulation of drugs versus dietary supplements
What will be an ideal response?
Drugs are strictly regulated by the FDA, where dietary supplements are not. The FDA is only required to investigate a dietary supplement in the event of an adverse event; drugs undergo strict procedures to provide evidence to support their safety and efficacy. Drugs must use labels and package inserts to report all potential adverse events, where supplements are not required to have safety warnings on labels. Finally, drug companies must report all adverse events to the FDA, where reporting of adverse events to the FDA related to supplement use is voluntary.
