How We Make Money
Affiliate commissions — and why they can’t touch the grades.
Short version: we earn a commission when you buy a supplement through some of our links. That money has zero influence on our evidence grades, on what’s in our index, or on which experts we track. Here is exactly how we keep it that way.
Where the money comes from
When you buy a supplement through one of our links, the retailer pays us a small commission. You pay the same price either way — it comes out of the retailer’s margin, not your pocket. We do not sell our own supplements, and we do not take payment from any brand, expert, or manufacturer to change what we publish.
Grades are computed first, from research only
A supplement’s evidence grade comes from published studies and tracked expert claims — calculated before any buy link is attached. The grading process has no idea whether a product earns us a commission.
Links are gated on product quality, not on the grade
We only attach a buy link when a specific product clears our published sourcing standards. That bar is about purity, potency, and honest labeling — never about who pays us, and never something a brand can pay to meet. If no product qualifies, we show you the checklist instead of a link.
No sponsored placements, ever
We do not sell ranking, badges, or featured slots. A supplement with a weak evidence grade is treated the same as a strong one. If we ever changed this, we would label it unmistakably — but our plan is to never go there.
See the bar a product must clear in our sourcing standards, how we build our data in how our data is made, and our editorial independence statement. Found a link that shouldn’t qualify? Tell us — a bad link is a bug in the thing we care most about.
