Affiliate disclosure

Some links on this site are affiliate links. If you buy through them, we may earn a commission at no extra cost to you. Commissions help fund our free research summaries and the upcoming community symptom tracker. They never influence which compounds we cover or what the research says about them.

Our retailer links point to Amazon, iHerb, Fullscript. Where we participate in a retailer’s affiliate program, purchases made through those links may earn us a commission. Retailer links are marked as paid links.

We may display advertising from third-party networks. Advertisers have no influence over our editorial content, and appearing next to an ad doesn’t mean we endorse the product advertised.

We plan to launch our own wellness store. When it opens, we’ll clearly identify our own products wherever they appear, and our research summaries will continue to cover compounds regardless of whether we sell them.

No company pays to be included on this site or to influence how the research is described. We choose which compounds to profile based on reader interest and the research available. Our product guidance focuses on quality markers such as form, standardisation and third-party testing, not on specific brands.

These statements have not been evaluated by the Food and Drug Administration. These products are not intended to diagnose, treat, cure, or prevent any disease.
