Supplement Brief publishes independent buying guides for people comparing supplements, GLP-1 companion nutrition, hair growth products, and longevity ingredients. Our editorial process is designed to make evidence, limitations, and commercial context visible before a purchase decision.
What we check
- Human evidence strength and whether claims match the cited research
- Realistic use cases, safety limits, and medication context
- Product form, dose, price, and whether the comparison is useful
- Affiliate relationships and whether rankings are paid
What we do not do
- We do not sell paid rankings or accept payment for placement
- We do not present supplements as replacements for prescription medication
- We do not publish miracle claims, before/after promises, or fake medical review badges
