Editorial standards

Supplement Magazine is an independent publication about vitamins, minerals, and dietary supplements. We exist because the space between a supplement’s marketing and its actual evidence is wide, and someone should stand in it honestly.

How we research

Every health claim we publish is traced to a primary source: a peer-reviewed study, a meta-analysis, a professional position stand, or an authoritative reference such as the NIH Office of Dietary Supplements. We link those sources so you can check our work. When the evidence is observational, we say so. When effect sizes are small, we say that too, in plain numbers.

How we review products

We only recommend a product when its ingredients have real published support and its price is reasonable. When a product is overhyped or a claim is unsupported, we say that instead, even when there would be a commission in recommending it. A recommendation you can’t trust is worth nothing to either of us.

Independence and affiliate disclosure

Some articles contain affiliate links. If you buy through one, we may earn a commission at no additional cost to you. That relationship never influences our assessment, and there is at most one clearly-marked buying option per article, always visually separated from the editorial content.

Not medical advice

Nothing here is medical advice or a substitute for a clinician. Supplements interact with medications and conditions. Talk to your doctor or pharmacist before starting anything new.
