An open, evidence-graded dataset of dietary-supplement clinical data — dosing, form/bioavailability, drug–nutrient interactions, population need, and cost-per-effective-dose product comparisons. Every clinical claim carries a PubMed PMID so it can be verified against the primary source.
Compiled and maintained by Verified Supplement Data. This repository is the canonical open mirror; the same data is available on Hugging Face (DOI 10.57967/hf/9356) and Kaggle, and as a free live JSON API.

Product data is normalized to cost-per-clinically-effective-daily-dose rather than cost-per-bottle, so products with different serving sizes and elemental content are comparable. Clinical claims are tied to PubMed identifiers (pmids / pubmed_ids columns). Certification reflects NSF / USP / IFOS third-party testing status. Deficiency prevalence is from NHANES; adverse-event signals are from FDA FAERS. Full method: https://verifiedsupplementdata.com/methodology/
