What Is Beta-Carotene?
Beta-carotene is the carotenoid that gives fruits and vegetable their orange and yellow pigment. It is a powerful antioxidant and has been found to help protect against cancer and aging. Beta-carotene may also slow down cognitive decline.
Beta-carotene is also known as “provitamin A” because the body converts it into vitamin A. Vitamin A is necessary for good vision and eye health, as it works to protect the surface of the eye, the cornea. It also contributes to a strong immune system and healthy skin and mucus membranes.
Eye Health Benefits of Beta-Carotene
Eye benefits of beta-carotene: when taken in combination with zinc and vitamins C and E, beta-carotene may reduce the progression of macular degeneration. Beta-carotene is a strong antioxidant, which protects the body from free radicals, which damage the body through oxidation.
Beta-carotene reduces oxidative stress placed on our eyes from blue light emitted from the sun and electronic devices. As beta-carotine converts into vitamin A, it helps to reduce the risk of macular degeneration and vision loss.
Excess vitamin A from animal sources is toxic, however, beta-carotene and provitamin A carotenoids from fruits and vegetables do not pose the same risk of toxicity, since these compounds are water-soluble and easily eliminated from the body.
