Quick Take

Food-first unless intake is low; avoid high-dose isolated beta-carotene, especially if you smoke.

Beta-carotene is a plant carotenoid found in carrots, sweet potatoes, spinach, kale, and pumpkin. The intestine converts part of it into retinol as needed, while some remains in tissues as an antioxidant pigment. Best-supported uses are improving vitamin A status when intake is low and modestly reducing UV-induced skin redness after consistent use; it may also help some photosensitivity conditions. It is most relevant for adults with low intake of colorful produce or low vitamin A status.

Food Sources

Carrots (~8,300 mcg beta-carotene per 1/2 cup cooked)
Sweet potato (~11,000 mcg per medium baked potato)
Spinach (~5,600 mcg per 1/2 cup cooked)
Kale (~5,400 mcg per 1 cup cooked)
Pumpkin puree (~9,000 mcg per 1/2 cup)
Cantaloupe (~2,700 mcg per 1 cup)

How It Works

Beta-carotene is absorbed with dietary fat and partly cleaved into retinal and retinol, which support vision and epithelial tissues. Unconverted beta-carotene can accumulate in skin and quench singlet oxygen, modestly reducing UV-driven oxidative stress and erythema.
