How we compare supplements
Transparent checks rather than invented scores or personal treatment advice
Checked on 2 November 2026What is checked
We compare declared ingredients, serving size, allergens, price basis, seller language and countries shown in the order form. Product pages distinguish manufacturer sample labels from our own observations.
What a comparison cannot establish
We have not laboratory-tested these products, reviewed your medical history or independently verified seller effectiveness claims. A checkout test confirms a purchase path, not clinical results or suitability.
Price and availability
Displayed USD amounts are dated snapshots of the selected two-package offers before delivery and tax. Sellers can change prices and terms. Follow the current order screen for the final amount.
Commercial transparency
We can receive a commission on an attributed purchase through a marked ClickBank link. We do not use fabricated ratings, reviews or promises of guaranteed results. Our informational iHerb links are not affiliate links.
Cost per serving calculator
Use the same currency for every amount — this tool does not convert currencies or recommend a dose
We may earn a commission through links marked “Affiliate link”. Orders and payments are handled by the seller. We are an independent guide, not iHerb.
Information for comparison, without individual dosing advice. Supplements do not replace a varied diet or prescribed treatment. Discuss use with a doctor or pharmacist.
