Primary Product Sources
Current labels, seller pages and official support/refund information are preferred for product-specific facts.
Scientific Sources
Systematic reviews, randomized trials, peer-reviewed journals and established medical institutions are preferred.
Regulatory Sources
FDA and other authoritative agencies are preferred for supplement-regulation context.
What We Treat Carefully
Affiliate pages, testimonials and press releases are weak evidence for efficacy.
Uncertainty
When sources conflict, we describe the conflict rather than force certainty.
