What it is: Beta-carotene is a naturally occurring carotenoid, a type of plant pigment, that serves as a precursor to vitamin A (provitamin A) in the body. It is not an active vitamin itself, but the body can convert it into vitamin A as needed.
What it does: Beta-carotene supports healthy vision, immune function, and the maintenance of skin and mucous membranes by supplying a source for the body to make vitamin A. It also acts as an antioxidant, helping protect cells from free radical damage.
How it is used: Beta-carotene is commonly used in supplements aimed at eye health, antioxidant support, general wellness, immune system balance, and skin maintenance.
Natural sources and supplement forms: Beta-carotene occurs in high amounts in colorful vegetables and fruits such as carrots, sweet potatoes, squash, and spinach. For supplements, it is typically sourced from the microalgae Dunaliella salina or produced synthetically, and is available in capsules, softgels, and multivitamin blends.
Why it appears in supplement formulas: It is favored for providing a regulated, plant-based source of vitamin A without the toxicity risk of preformed vitamin A, and for its benefits to vision, immune defenses, and antioxidative activity.
What to know before use: Large amounts from supplements may cause harmless orange skin discoloration. High-dose beta-carotene supplements are not recommended for smokers or people with a history of lung disease due to possible adverse effects; professional guidance is advised in these cases.
