How We Test Supplements
Every product we cover gets at least a few weeks of daily use. We don't score supplements we haven't taken ourselves. Here is exactly what we look at.
The five scores
- Ingredient quality — sourcing, form, and whether the actives are the ones that work.
- Dosing — are the amounts clinically meaningful, or under-dosed for label appeal?
- Third-party testing — NSF, Informed Sport or USP certification and transparent labels.
- Value — cost per effective serving, not just the sticker price.
- Taste & mixability — whether you'll actually keep taking it.
What we don't do
We don't rank products by who pays us, and we flag proprietary blends and under-dosed formulas. Scores can change as brands reformulate — we re-test major changes.
