As a supplement

Talk to your doctor or pharmacist.

Roll Call does not check drug interactions or assess personal safety.

A trace metallic element occasionally included in multi-mineral supplements. It occurs naturally in small amounts in some foods.

Why it’s used

Included in some ultra-trace mineral blends, though it has no established nutritional role in humans.

What the evidence says

There is no recognized dietary requirement for tin in humans, and no established evidence that supplementing with it produces any benefit. Data on its biological role, if any, remain very limited.
