Editorial principles
Our content is written to help readers understand product information, buying terms, supplement safety and evidence quality. We prefer precise qualification over promotional certainty.
Source hierarchy
- Authentic current product label, when available.
- Current checkout and seller support information.
- FDA, NIH/NCCIH and other authoritative agencies.
- PubMed-indexed peer-reviewed human research.
- Secondary sources only for context, not as proof.
Claims policy
We do not convert ingredient research into finished-product clinical proof. We do not claim dietary supplements diagnose, treat, cure or prevent disease. Vendor-reported package details are identified as such and can change.
Corrections and updates
Pages show a last-updated date. Material changes to price, shipping, guarantees, ingredients or evidence should trigger a content review.
Commercial links
Affiliate links are labeled through disclosure and use rel="nofollow sponsored noopener". We do not use direct seller URLs on this site.
