Beta-carotene is a naturally occurring red-orange pigment belonging to the carotenoid family and is widely found in fruits and vegetables such as carrots, pumpkins, and leafy greens. It serves as an important precursor of vitamin A, which is essential for vision, immune function, and overall growth. Beta-carotene also acts as a potent antioxidant, helping protect cells from oxidative damage caused by free radicals. Due to these properties, it is commonly used as a dietary supplement to prevent vitamin A deficiency, support eye and skin health, and enhance immune function. Additionally, beta-carotene is used as a natural food colorant and in pharmaceutical and cosmetic products for its health-promoting benefits.
