Description
“Alpha-Carotene” is a naturally occurring carotenoid found in orange and yellow vegetables such as carrots, pumpkin, and sweet potatoes. It belongs to the provitamin A group, meaning the body converts it into retinoids when needed. Alpha-carotene participates in metabolic pathways related to oxidative balance, cellular maintenance, and epithelial health. It also promotes skin integrity, vision support, and immune resilience. As a dietary carotenoid, alpha-carotene supports structural stability and metabolic processes within the body.
