How we review supplements
Every guide is researched against published sources, written in plain language, and reviewed by the FactoWiki Editorial Team for clarity and source accuracy before it is published. We describe what research suggests — never what we wish it showed — and we avoid words like "cure," "guaranteed" or "miracle." Read our full editorial policy to see how we work.
Safety first
FactoWiki provides educational information, not medical advice. Supplements can interact with medications and aren't right for everyone. Always speak with a doctor or pharmacist before starting one — especially if you are pregnant, nursing, taking medication, or managing a health condition.
