About Gut Signal Guide

What we do

Gut Signal Guide is an independent educational publication focused on the overlap between the gut microbiome, metabolic health and supplement marketing. Our goal is to help readers distinguish plausible biology from proof of a finished consumer product.

How we make money

Some Trimology links on this site are affiliate links. If a reader purchases through one of those links, the publisher may earn a commission. We do not let that relationship justify fabricated product testing, invented testimonials or unsupported medical claims.

What we do not claim

We have not personally tested Trimology unless a page explicitly states otherwise. We do not diagnose, prescribe or replace a clinician. We do not treat merchant testimonials as clinical evidence.

Research standard

We prefer primary research, systematic reviews and authoritative health/regulatory sources for medical or scientific context. Merchant pages are used to document what the seller currently claims, how the offer is structured and what the seller discloses.
