The Three Background Sources: FDA, FTC & NIH, Explained

This site cites three specific sources with a direct disclaimer attached: none of these organizations endorses the product or this review.

What the three sources actually are

The U.S. FDA's page on dietary supplement regulation and consumer information, the FTC's Health Products Compliance Guidance, and the NIH Office of Dietary Supplements' general fact-sheet list.

Why this site frames these as background reading, not evidence
