This page explains the rules every ValueReviewHub article follows. If an article falls short of them, we want to know.
1. Sources we rely on
- Official product information: the manufacturer’s website, order page, refund policy, shipping policy and label. Prices and guarantees are copied from these pages and dated.
- Government and public health sources: NIH Office of Dietary Supplements, NCCIH, CDC, FDA and NIDDK.
- Peer-reviewed research: we prefer systematic reviews, meta-analyses and randomized controlled trials in humans, and we say when evidence comes only from cell or animal studies.
2. Claims versus evidence
We label three things separately: what the manufacturer claims, what the published evidence shows, and our editorial interpretation. Research on a single ingredient does not prove that a multi-ingredient product works, especially when doses are hidden in a “proprietary blend”.
3. What we will not publish
- Fake reviews, testimonials, ratings or awards.
- Invented prices, discounts or countdown-style urgency.
- Claims that a supplement treats, cures or prevents a disease.
- First-hand testing claims that did not happen.
4. Prices and policies
Supplement prices and guarantees change. Every review shows the date we last checked the official website. Always confirm the current price and refund terms on the official site before ordering.
5. Affiliate links
Affiliate relationships are disclosed on every page that contains them. Links to merchants are marked as sponsored. A commission never buys a positive review. See our Affiliate Disclosure.
6. Corrections and updates
If you spot an error, contact us through the Contact page with the article link and the source that shows the correct information. We review every report, correct confirmed errors promptly, and update the date on the article only when the content genuinely changes.
7. Medical information
Our content is educational and is not medical advice. Please read our Medical Disclaimer.
