Who We Are
TrustZeta is an independent, reader-supported publication that reviews health and vitality supplements. Our reviews are researched and written by the TrustZeta Editorial Team — researchers and writers who read published studies, ingredient labels, and manufacturer disclosures so readers don’t have to. We are not physicians, and nothing on this site is medical advice. Our work is editorial analysis of publicly available information.
How We Score (Editorial Score)
Every review carries an Editorial Score out of 5. It is our editorial opinion based on stated criteria — not a clinical result, a lab test we performed, or a measure of sales. We weigh three things:
- Ingredient & Evidence (50%) — Are the active ingredients disclosed at meaningful doses, and what does the published, peer-reviewed research actually say? We note where human evidence is strong, preliminary, or thin.
- Manufacturing Transparency (25%) — Does the maker state GMP compliance, an FDA-registered facility, and a transparent label?
- Buyer Protection (25%) — How strong is the money-back guarantee, and what does publicly available customer feedback suggest about real-world risk?
Our Promises to Readers
- No pay-for-placement. A higher commission never buys a higher score or ranking.
- We flag weak evidence plainly, even for products that could earn us a commission.
- We don’t fabricate. We never invent customer testimonials, fake “verified buyer” reviews, or numeric results we didn’t actually assess.
- We disclose. Affiliate relationships are disclosed openly on every page. See our Affiliate Disclosure.
How We’re Funded
TrustZeta is reader-supported. When you buy through links on this site we may earn a commission at no extra cost to you. This funds our research and never affects our assessments.
Corrections
If you spot an error or have new evidence about a product we’ve reviewed, contact us and we will review and correct the record. Supplements are not intended to diagnose, treat, cure, or prevent any disease, and these statements have not been evaluated by the FDA. Always consult a qualified healthcare professional before starting any supplement.
