Our sources policy is simple: use seller-controlled sources to document seller claims, and use independent sources to evaluate ingredients, safety and general evidence.
Source Hierarchy
- Government health resources such as NIH ODS and NCCIH.
- Peer-reviewed human research and systematic reviews when directly relevant.
- Official product pages for label, serving, pricing, shipping and refund claims.
- Customer reports only when they can be clearly identified and responsibly contextualized.
What Vendor Sources Can Prove
Vendor sources can establish what the vendor currently says about its product and commercial policies. They cannot independently prove the clinical accuracy of the vendor's health claims.
What Ingredient Sources Can Prove
Ingredient sources can describe evidence for an ingredient under specific conditions. They do not automatically prove that a finished multi-ingredient product has the same effect.
Corrections
If you find a factual error or a source that has changed, contact the editorial team. We will review the correction against the source and update the page when warranted.
