Frequently Asked Questions
What data does PlainVitamins provide?
PlainVitamins provides NIH Dietary Supplement Label Database (DSLD) records covering 113,539 product labels, 4,406 brands, and 4,622 distinct ingredient groups. Inclusion in the DSLD is a label-on-file record, not an FDA approval or efficacy verification.
Can I compare supplement brands?
Yes, browse by brand, ingredient, or product type to compare label claims and serving sizes across products. Per-ingredient amounts and Daily Value percentages are shown when manufacturers disclosed them on the label submitted to the NIH; rows that lack these values display "Not disclosed on label" rather than a fabricated number.
Where does the data come from?
All label data is sourced from the National Institutes of Health (NIH) Office of Dietary Supplements (ODS) Dietary Supplement Label Database (DSLD), which catalogs supplement labels marketed in the United States. Reference Daily Value (DV) percentages follow FDA 21 CFR 101.9 / 101.36. Editorial commentary and ingredient context is compiled by our editorial team.
