Method
A plain description of how this tool works and what it does not claim.
Rankings are transparent and editable
Each candidate is rated 0–5 on four criteria. The score is a weighted average scaled to 100. Default weights:
- Evidence30%
0 none · 1 mechanistic · 2 animal · 3 small human trials · 4 multiple RCTs · 5 consistent meta-analyses for this form
- Quality / testing30%
0 unknown · 1 claims only · 3 published CoA · 5 independent third-party tested (identity, potency, contaminants)
- Formulation / dose25%
0 unclear · 1 underdosed or wrong form · 3 reasonable · 5 studied form at studied dose
- Cost15%
0 unknown · 1 very expensive per active mg · 3 typical · 5 among lowest per active mg
You can change the weights and every rating. Nothing is hidden, and nothing is verified by us. Candidates and saved comparisons live only in your browser.
Sourcing standards
- Product data comes from the label. Where it was transcribed from a screenshot, it is marked unverified.
- Prefer candidates with a published certificate of analysis or independent third-party testing.
- Compare cost per matching active mg (e.g., mg of bacosides, actual CoQ10), not per capsule.
- No brands, prices or reviews are pre-filled. Empty cells say "Not researched yet". Demo rows are labeled hypothetical.
No equivalence or medical claims
Two products with the same ingredient name are not automatically identical or equivalent. Extracts, forms and doses differ, and so may effects. Nothing here claims a supplement treats, prevents or cures any condition. Evidence grades are qualitative summaries with real uncertainty.
Safety flags
- Ginkgo: may increase bleeding risk, especially with anticoagulants, antiplatelets or NSAIDs, and around surgery.
- Caffeine: stimulant; may affect sleep, anxiety, heart rate and blood pressure. Count other sources.
- Selenium: 200 mcg is above the adult RDA (55 mcg) and below the tolerable upper intake level (400 mcg). Stacking products can exceed the UL.
- Verify with a clinician, particularly if you take medications or are pregnant or breastfeeding.
Evidence sources and review status
Guidance distinguishes human randomized trials and systematic reviews, preliminary or mechanistic evidence, and unsupported marketing claims. It links to NIH Office of Dietary Supplements and NCCIH reference pages where available, plus clearly labelled PubMed research searches. A search link is not a selected paper or completed review.
Pending review means the editorial summary has not been formally reviewed. A last-reviewed date appears only when a review record exists. Source links do not make a summary personalized medical advice or prove that a product works.
Professional, member and sponsored content
No professional perspectives are published in this demo. Future professional attribution requires a separate credential-verification process; claiming a credential never generates a verified badge automatically.
Member experiences remain anecdotes. Sponsored content must be labelled and cannot alter independent evidence scores or rankings.
Community and commercial independence
Community experiences are anecdotes, never clinical evidence. Local reports flag misinformation, unsafe dosing, undisclosed promotion and harassment; no human moderator monitors this demo.
Brand representatives must be visibly distinct from independent members. Brand submissions and answers are unverified statements requiring review. Brands never edit independent evaluations or evidence grades.
A verified-brand label is an identity or documentation signal, not endorsement. Sponsored placements are paid visibility, clearly labelled SPONSORED and separate from independent rankings and evidence scores. No sponsorship payment buys a favourable evaluation.
All community, brand and sponsor entries are local demo state. There is no live network, file upload service, actual verification, sponsor or payment flow. Submitted material remains a local draft, never automatically published.
