DisclosureWe earn commission on partner links; ranking is set by our evidence-based methodology — not advertisers. Read policy
The complete scoring rubric, per-page weights, and review process. We publish everything — including the source-code constants that drive our rankings. We are fully independent: we sell no products of our own, and affiliate revenue never changes a ranking.
Each scored on the same 6-axis rubric

Every product on this site is scored 0–10 on six axes by editorial staff against primary sources. The axes are weighted differently per page template (a diabetes page weights A1C reduction higher than a cash-pay cost page).
Not every page weighs axes equally. On a “best for type 2 diabetes” page, effectiveness and safety dominate. On a “best in California” page, accessibility matters more. The literal weight constants below are pulled live from src/lib/ranking.ts. When that file changes, this table changes.
| Page template | Effectiveness | Safety | Value | Accessibility | User experience | Trust |
|---|---|---|---|---|---|---|
| Default (homepage, generic rankings) | 30% | 25% | 10% | 10% | 10% | 15% |
| Best [product] for [condition] pages | 40% | 30% | 5% | 5% | 5% | 15% |
| Best [product] in [location] pages | 25% | 20% | 10% | 25% | 10% | 10% |
| Head-to-head comparison pages (X vs Y) | 35% | 25% | 10% | 5% | 10% | 15% |
| Alternatives to [product] pages | 30% | 25% | 15% | 10% | 10% | 10% |
| Best [category] pages | 35% | 25% | 10% | 10% | 5% | 15% |
Emerald percentage = highest weight per template. Every template’s weights sum to ~100%.
Each product has an optional manualOrder field. When set, it overrides the computed score and forces a fixed position. We use this sparingly. For example, we may bump an FDA-approved product above a compounded one even when the math is close, because we believe regulatory safety should weigh higher than the algorithm sometimes admits. Every manual override is logged in our editorial changelog.
Every clinical claim is checked against primary sources — FDA labeling and peer-reviewed studies — and linked inline through our review process before it ships. We link the underlying source inline so any claim can be traced. If a claim cannot be sourced, it does not ship.
The six-axis rubric is the only input to scoring. We have affiliate relationships with some brands we cover and not with others. When a product without an affiliate relationship outscores one with, the unmonetized product still ranks higher. See our affiliate disclosure for full details.
