Editorial independence. Affiliate-linked — commissions never influence scores or ranking order
The supplement industry spends billions marketing things that don't work. We spend our time reading the research so you don't have to.
Why it matters

Three principles that don't change.

01

Database-powered scoring

Every product and ingredient lives in a structured database with dose, form, extract, and supplier data. Reviews are queries against hard data — not editorial opinions dressed up as analysis.

02

Evidence-tiered claims

Every claim is tagged with a specific citation, evidence tier (RCT / meta-analysis / observational), and dosage range. No vague "studies show" language — ever. You'll always know exactly what the science says and how strong it is.

03

Affiliate-linked. Editorially independent.

We earn commissions through Amazon Associates and Awin when you buy via our links — this is how the site is funded. What we don't do: let commission rates influence scores, rankings, or which products we cover. Our scoring rubric runs before we know what any affiliate pays. Full disclosure policy →

Our methodology

Five questions.
Same rubric.
Every time.

Dose, form, purity, value, and label honesty. Each is scored 0–10 against a written standard. No reviewer discretion. No score inflation. The weights haven't changed since we published them in 2024.
