What does the FDA's relaxed regulation of dietary supplements imply?

The correct answer highlights that dietary supplements can be marketed without prior FDA approval. This reflects the regulatory framework established by the Dietary Supplement Health and Education Act (DSHEA) of 1994, which allows manufacturers to bring supplements to market without needing to demonstrate safety or effectiveness to the FDA before selling them. Instead, the responsibility falls to the FDA to prove that a supplement is unsafe after it has been marketed, contrasting with medications that must provide evidence of safety and efficacy prior to approval.

This lenient regulation means that while dietary supplements must comply with certain manufacturing practices and labeling requirements, they do not need to provide clinical trial data prior to marketing. Thus, consumers and healthcare providers need to be aware that the evidence supporting the claims made by these products may not always be robust, as they do not undergo the same rigorous testing processes that pharmaceutical drugs do.
