Beta-carotene
A provitamin A carotenoid found in orange, red and dark-green plant foods.
Beta-carotene can be converted to retinol, but conversion varies with food, diet, genetics and health status.
What the form means
Beta-carotene is a dietary precursor rather than preformed vitamin A. EFSA expresses its vitamin A activity through retinol equivalents, while the molecule also remains a carotenoid in its own right. High-dose beta-carotene supplements increased lung-cancer and lung-cancer-death risk in a trial of current and former smokers.

Beta-carotene can be converted into Vitamin A
Beta-carotene is a provitamin A carotenoid that the body can convert into vitamin A.
Worth knowing
A vitamin A precursor. Beta-carotene is a plant pigment that the body can convert into vitamin A. Orange, red and dark-green plant foods can provide it, but the amount converted varies between people and foods.
Not every carotenoid is provitamin A. Lycopene, lutein and zeaxanthin are carotenoids, but they are not converted into vitamin A. A colourful food is not therefore a shortcut to estimating vitamin A activity from colour alone.
A closer look
Food preparation changes availability
Cooking and heat treatment can make beta-carotene more bioavailable from some foods. That is one reason a nutrient database value is a composition measure, while vitamin A activity in a meal also depends on the food matrix and preparation.
