supplementscore.org — a non-profit, evidence-based supplement reference. No sponsorships, no affiliate links, no paid placements.
Every supplement is scored from peer-reviewed clinical trials and meta-analyses. Sources are weighted by funding independence and methodological strength. When the evidence changes, the score changes — and we keep a public log of every reversal.
This is the static site that powers supplementscore.org. It deploys directly to GitHub Pages from main.
| Surface | Count | Path |
|---|---|---|
| Supplements scored | 758 | data.js (canonical), s/*.html (per-supplement detail pages) |
| Articles | 241 | a/*.html |
| Condition deep-dives | 20 | condition/*.html |
| Comparison guides | 5 | compare/*.html |
| Symptom-domain hubs | 16 | sx/*.html |
| Population-targeted lists | 7 | for/*.html (athletes, kids, women, men, pregnancy, seniors, vegans) |
| OG social cards | 534 | og/*.svg (auto-generated, one per supplement) |
| Languages | EN + FR (partial) | fr/ for French content |
Total: ~850 indexable HTML pages, all with their own canonical URL, meta description, and JSON-LD where appropriate.
Each supplement is scored on six independent dimensions, each on a 1–5 scale:
| Dimension | Weight | What it measures |
|---|---|---|
| Efficacy | ×7 | Strength + replication of clinical evidence |
| Safety | ×4 | Adverse-event profile in healthy adults at recommended dose |
| Research depth | ×3 | Number and size of independent trials |
| Onset | ×2 | Time-to-effect (acute vs cumulative) |
| Cost | ×2 | Per-month cost at clinical dose |
| Drug-interaction risk | ×2 | Major-medication interactions (5 = lowest risk) |
Composite score: e×7 + s×4 + r×3 + o×2 + c×2 + d×2. Maximum 100.
Tier mapping:
- Tier 1 (≥72): Strong evidence, recommended.
- Tier 2 (60–71): Promising or situational.
- Tier 3 (40–59): Trending or thin evidence — use with caution.
- Tier 4 (<40): Documented harm or banned in major jurisdictions — avoid.
Tier 1 placement requires at least one independently funded randomised controlled trial confirming the effect — industry-only evidence cannot drive a Tier 1 call. See methodology.html, editorial-pipeline.html, and funder-policy.html for the full framework.
Scores draw exclusively from peer-reviewed primary literature and credible institutional positions:
- Primary literature: PubMed, Cochrane Library, ClinicalTrials.gov, bioRxiv, ChEMBL
- Institutional positions: NIH ODS, FDA, EFSA, WHO, EMA, Health Canada, MedlinePlus
- Tertiary: Lancet, NEJM, JAMA, BMJ for editorial context only
A complete source registry lives in sources/registry.json (in the parent project folder, not the deployed site).
- No sponsorships
- No affiliate links
- No paid placements
- No supplement company funding (ever)
- All page content is editorially independent
Industry-funded trials are not excluded from scoring, but they cannot solo-promote a supplement to Tier 1, and conflicts of interest are disclosed inline where they exist. See funder-policy.html.
