Frequently asked questions
Everything you need to know about how we review supplements.
How do you choose which supplements to review?
We prioritise the products our readers ask about most, the best-selling products in each category, and new formulas making bold claims that deserve scrutiny.
Are your reviews sponsored?
No brand pays for a review or a rating. Some links on the site are affiliate links, which means we may earn a commission if you buy through them, at no extra cost to you. Commissions never influence our verdicts.
How are ratings calculated?
Each review weighs ingredient evidence, dosing transparency, third-party testing, value per serving and taste or mixability. Reader ratings are shown separately from our editorial verdict.
Can I leave my own review?
Yes. Create a free account, verify your e-mail address, and you can rate and review any supplement, article or product image. Reviews are moderated before they appear.
Is this medical advice?
No. Our content is for general information only. Talk to a qualified healthcare professional before starting any supplement, especially if you have a medical condition or take medication.
How often are deals updated?
Our team checks deals daily. Each deal lists an expiry date when one is known, but prices can change at the retailer at any time.
