Understanding FDA Supplement Regulation

In the United States, dietary supplements are regulated under the Dietary Supplement Health and Education Act (DSHEA) of 1994. Unlike prescription drugs, supplements do not require FDA approval before being sold to consumers. Manufacturers are responsible for ensuring their products are safe and that label claims are truthful, but the FDA does not verify these claims before products reach store shelves.

This regulatory framework means that supplement quality, purity, and potency can vary widely between products. The FDA can take action against supplements found to be unsafe or mislabeled after they are on the market, but proactive testing is limited. This is why independent third-party testing and transparent labeling are so important for consumers. Zynava does not test or verify products — we encourage you to read labels carefully and look for third-party testing claims from the manufacturer.
