Methodology
Categories on this page map directly to the classification codes assigned by the Source: NIH Office of Dietary Supplements, Dietary Supplement Label Database (DSLD). Product types use the DSLD's nine supplement category codes (A1299 Mineral, A1302 Vitamin, A1305 Amino Acid & Protein, A1306 Botanical, A1309 Non-Nutrient, A1310 Fat & Fatty Acid, A1315 Multi-Vitamin & Mineral, A1317 Botanical with Nutrients, A1325 Other Combinations). Ingredient categories roll up individual ingredient groups by the broader nutrient family they belong to.
Product-count totals in each category reflect how many filings in the DSLD contain at least one ingredient in that group, useful for seeing which nutrients dominate the US supplement market. Counts are deterministic queries against the latest DSLD export; there is no editorial weighting. Regulatory context follows Source: Dietary Supplement Health and Education Act (DSHEA), 1994, 21 U.S.C. § 321(ff), which governs how supplements are labeled, marketed, and cataloged.
Not medical advice. Category membership is a classification signal, not an endorsement of any specific nutrient or product. The NIH DSLD catalogs what manufacturers declare on their labels; it does not evaluate safety, efficacy, purity, or claimed benefits. Consult a licensed healthcare provider before starting, stopping, or combining any dietary supplement, especially if you are pregnant, nursing, take prescription medication, or have a medical condition.
