provitamins

Inactive vitamin forms

Provitamins are substances the body converts into vitamins.

Beta-carotene is a provitamin that becomes vitamin A; certain forms of cholesterol become vitamin D when exposed to sunlight.

The term distinguishes these precursors from vitamins themselves, which the body uses directly: Carrots are rich in provitamin A.
