Affiliate disclosure

Protocol recommends supplements and products, and some of the “Buy” links on this site are affiliate links. If you click one and make a purchase, we may earn a commission. This comes at no additional cost to you — you pay the same price you would otherwise.

Affiliate links carry the standard rel="sponsored nofollow" attributes, and we mark them wherever they appear.

This is the important part. We choose products first — based on what the evidence supports and whether they're clean and third-party-tested — and only then attach an affiliate link if a program exists. We do not rank, feature, or recommend a product because it pays more. If the best pick in a category has no affiliate program, it's still the pick.

We add affiliate programs as they approve us. These currently include or may include retailers and brands such as iHerb and direct brand programs (e.g. Momentous, Thorne, LMNT).

Affiliate relationships don't change the bigger rule: everything here is general wellness and nutrition information, not medical advice. We help with nutrition, never with your medication. Talk to your clinician or pharmacist about your medication and routine.
