Editorial Independence
Our team writes and sets every review, score, and ranking on this site. We use the five-part scale in How We Test. No brand gets to see, approve, or shape a review before it goes live. This includes brands tied to this site's owner. Our sales team sets up affiliate deals. It has no say in scores.
No Sponsored Rankings
We do not sell placement. A product's score alone sets its spot on any list, full stop. We earn money when readers click affiliate links, not when a brand pays us. We've turned down "pay for a higher score" requests. If we ever take free products or press samples for testing, we say so in the review. It never changes the score.
We also review products from brands under common ownership with this site, including Meo Nutrition. Those get the same rubric as every competitor, cons included. See our Affiliate Disclosure for details.
Correction Policy
We get things wrong sometimes. A formula changes, a lab result gets replaced, a link breaks. When a reader, a brand, or our own re-check flags an error, we check the source and update the article. We add a visible "Updated" date at the top. Material fixes — anything that changes a score or a ranking — get a note right where the change happened. We never edit rankings in silence.
Think we got something wrong? Email hello@supplementlab.org with the article URL and what you're seeing. We read every message.
Medical Disclaimer
Results vary by person. When we call something effective, that reflects published research and outside data we've gathered — not a promise for any one reader.
