α-Carotene is widely used in the nutraceutical and dietary supplement industries due to its potent antioxidant properties. It is often included in formulations aimed at promoting eye health, as it helps protect against age-related macular degeneration and supports overall vision. Additionally, it is incorporated into skincare products for its ability to neutralize free radicals, reducing oxidative stress and preventing premature aging of the skin. In the food industry, it serves as a natural colorant, providing a yellow to orange hue to various products. Its role in supporting immune function and reducing the risk of chronic diseases, such as cardiovascular conditions, makes it a valuable component in functional foods and health-focused beverages.
