# 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](https://verifiedsupplementdata.com), 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
