Every review on this site is written from public information: the product’s label and ingredient list, the manufacturer’s own sales page, published research on each ingredient, and the price and guarantee terms. We do not buy and lab-test every product ourselves, so our scores reflect what can be verified from those sources.
Disclosed ingredient doses; the strength of the evidence for each ingredient (human trials versus lab or animal studies); how far the seller’s claims go beyond that evidence; the monthly price and refund terms; and safety notes, interactions and who should avoid the product. Our editorial policy explains the process in full and our about page says who we are.
Many “Check Price” buttons are affiliate links, marked as sponsored, and we may earn a commission if you buy through them at no extra cost to you. We tell you about downsides and undisclosed doses in the review itself, but you should weigh our picks with that commission in mind.

We have published 146 supplement reviews across 20+ categories, including weight loss, brain health, blood sugar, vision, gut health, joints, dental, hearing, sleep, lung health and men’s health.

Each review compares the label with published research on its ingredients, checks whether doses are disclosed, and looks at price, guarantee terms and the claims the seller makes. Scores such as 8.3/10 are our editorial judgement of those factors, not laboratory test results.

No. In the United States the FDA does not approve dietary supplements for safety or effectiveness before they are sold. Manufacturers are responsible for the safety of their products and the accuracy of their labels. Check for third-party testing, look for interactions with any medicines you take, and speak to a doctor or pharmacist before starting a supplement.
Glycinate pairs magnesium with the amino acid glycine and is generally gentler on the stomach, so it is often chosen for daily use. Citrate is usually cheaper and has a stronger laxative effect at higher doses. Our magnesium glycinate vs citrate comparison covers both.
Monohydrate is the most studied form of creatine and is usually the cheapest. HCl is marketed as more soluble at smaller servings, but there is far less research behind it. Our creatine monohydrate vs HCl comparison sets out the details.
Yes. We offer 15 free tools, including a supplement selector quiz and calculators. You can find them all on the free tools page.
Read the full ingredient list and look for doses, and be wary of “proprietary blends” that hide amounts. Check the refund policy and who ships the product, compare the price on the official site, and talk to a healthcare professional first if you are pregnant, take medication or have a health condition.
