Supplement Evidence Dataset v1

A curated, evidence-graded dataset of 64+ supplement products across 14+ categories. Every product includes elemental dose, cost-per-day, third-party certification status, clinical evidence grade, and PubMed citation IDs.

Dataset Summary

Built by Verified Supplement Data, this dataset fills a gap in publicly available structured supplement data. Most supplement information online is marketing copy. This dataset standardizes the facts that matter: what form is it, how much active ingredient per serving, what does it actually cost per day, is it third-party tested, and what does the clinical evidence say.

Key features:

Elemental/active dose per serving (not compound weight)
Cost-per-day at clinical dosing targets
Third-party certification status (USP, NSF, IFOS, Informed Sport, etc.)
Evidence grade based on systematic reviews, meta-analyses, and RCTs
PubMed IDs linking to the specific studies behind each evidence grade
Editorial picks (best-value, quality, budget, plant-based)

Use Cases

Consumer health apps: Power supplement comparison tools with structured, evidence-based data
Research: Analyze supplement market pricing, certification coverage, and evidence quality
AI/LLM training: Provide factual supplement data with verifiable citations
Journalism: Data-driven supplement industry analysis
