β-Carotene
Overview
Beta-carotene is a carotenoid pigment found in many orange, yellow, and dark green plant foods. It serves as a precursor to vitamin A, which is essential for vision, immune function, and neuronal development. Beta-carotene functions as a potent antioxidant, scavenging reactive oxygen species and helping stabilize cell membranes. It also exhibits anti-inflammatory properties and supports immune regulation. The absorption of beta-carotene and other carotenoids is significantly enhanced when consumed with dietary fats, making food pairing important for maximizing bioavailability.
