Source Priority
We prioritize government health agencies, peer-reviewed journals, systematic reviews, established medical organizations and current primary product materials.
Seller Pages
Seller pages are appropriate for current price, package, guarantee and marketing-claim information, but not as independent proof of efficacy.
Research Studies
We prefer human clinical research relevant to the ingredient form, dose and outcome.
Testimonials
Testimonials are not treated as clinical evidence and may be subject to selection bias.
Conflicts & Sponsorship
Study funding and author conflicts are considered when they are available.
Stale Information
Commercial information can expire quickly; readers should verify live checkout details.
Corrections
Readers can use the contact page to flag a source or factual issue.
