We sell supplements and we review supplements, including our own. That is a conflict of interest. This page explains what we do about it, so you can judge whether it's enough.
Last updated 2 September 2026
We read the human trials for one ingredient and one outcome, and assign Strong, Moderate or Limited. No product is in the room at this stage.
A product's only score is how many of its actives hit the dose those trials used. It is arithmetic, not judgement, so we can't quietly flatter ourselves.
Where we own a product, that appears in a banner above the review — not only in the footer, and never after the recommendation.
We sell our own formulas. That is nearly all of our revenue, and it is the conflict that matters. Eleven products, all listed on one page with their dose scores, including the ones scoring 1 of 5.
We take no payment for coverage. No brand can buy a review, a grade, a placement in a comparison, or a spot in the newsletter. We have declined this.
No affiliate links. We earn nothing when you buy a competitor's product on our recommendation — which is the point, because sometimes we do recommend that.
No ads, no ad trackers. Two cookies: your basket and an anonymous page count.
A policy page is a promise, and we are the ones grading our own homework. Three honest limits:
Grading is mechanical; deciding which ingredients get a page is not. We cover the areas we sell into more thoroughly than the ones we don't.
Much supplement research is paid for by supplement makers. We note funding on each trial, but we can't correct for it.
No external body checks this policy. The only real accountability is that our claims are checkable against the papers we cite.
When we get something wrong we fix the page and add a dated note at the bottom saying what changed. We don't silently edit. If a grade changes because new trials landed, the article says so and keeps the old conclusion visible.
Send the page and the specific claim you're disputing from the contact page. We reply within two working days, including when the answer is that we stand by it.
