About Sift Nutrition

The supplement industry has a trust problem. Most “review” sites are sales pages in disguise — five stars for whatever pays the highest commission, miracle language, and no mention of the actual research.

Sift Nutrition exists to do the opposite: read the published studies on each ingredient, and tell you plainly what they support and what they don't — even when that makes a product less appealing. If an ingredient's evidence is weak, we say so. If a product's best-known ingredient failed its biggest trials, we say that too, on the same page where we review it.

Our reviews are produced by the Sift Nutrition editorial team and led by our research editor. We are researchers, not clinicians: we hold no medical credentials, we do not claim any, and nothing on this site is medical advice. Our trust currency is different — every evidence claim links to the underlying published research, and every review grades ingredient evidence honestly (strongest / moderate / mixed / limited).

How we make money, disclosed plainly: some links on this site are affiliate links. If you buy through them, we earn a commission at no extra cost to you. Disclosure appears on every page that contains an affiliate link, above the link — and the assessment is written from the ingredient evidence before any link is added. There is no way to buy a verdict on this site.
