Beta-Carotene
Beta-carotene is a plant-derived antioxidant and vitamin A precursor essential for vision, immune, and skin health, but high-dose supplements increase cancer risk in smokers.
Beta-carotene is a carotenoid pigment found in colorful fruits and vegetables. It serves as a major dietary source of provitamin A, supporting vision, immunity, and overall antioxidant protection. While generally safe from food, supplementation is not universally recommended due to risks in certain populations.
Benefits are best supported for prevention of vitamin A deficiency and general antioxidant protection; supplement safety concerns for specific groups (smokers, asbestos exposure) are well established.
Supports eye health and vision
ModerateBeta-carotene is a provitamin A carotenoid that supports retinal function and may reduce the risk of age-related macular degeneration when consumed as part of a carotenoid-rich diet.
Antioxidant protection
ModerateActs as an antioxidant, neutralizing reactive oxygen species and contributing to cellular protection against oxidative stress when obtained from food sources.
Supports immune function
ModerateBy converting to vitamin A, beta-carotene contributes to healthy mucous membranes and immune responses, lowering the risk of deficiency-related infections.
Supports skin health and photoprotection
LimitedBeta-carotene may offer modest protection against UV-induced skin damage and supports skin health, but is not a replacement for sunscreen.
