Primary Product Sources
Seller pages, current labels and official support/refund pages are preferred for product-specific commercial facts.
Scientific Sources
We prioritize systematic reviews, randomized controlled trials, reputable journals and established medical institutions.
Regulatory Sources
FDA and other authoritative agencies are preferred for supplement-regulation context.
What We Treat Carefully
Affiliate pages, press releases, anonymous blogs and testimonials can help identify claims but are weak evidence for efficacy.
Conflicts & Uncertainty
When reliable sources conflict, we describe the uncertainty rather than forcing a definitive conclusion.
