Editorial Policy: Sources, Corrections & Conflicts
Our publication standard is to prioritize verified facts and clearly label uncertainty. A seller’s marketing claim and an independent clinical conclusion are not interchangeable.
Source hierarchy
- Current authenticated product label and official seller terms.
- Current offer and checkout conditions.
- Seller support answers documented in writing.
- US government health agencies, including NIDDK, NIH/NCCIH, FDA and NCI.
- Peer-reviewed evidence evaluated for relevance, study design and limitations.
Evidence classification
Statements based on marketing are labeled seller-reported. Evidence about ingredients is presented as ingredient research. We do not claim that standalone studies establish finished-product outcomes unless finished-product trials are independently verified.
Corrections
We record article update dates and revise factual errors or superseded information. Important commercial terms such as shipping prices, label ingredients and refund rules should be rechecked before each substantial update.
Commercial independence
Affiliate commissions can create conflicts of interest. Our rules prohibit made-up ratings, fabricated testimonials, unverified medical endorsements, fake urgency and invented price guarantees. See our compensation disclosure.
