Beta-Carotene — Uses, Dosage, Side Effects & Safety

Drug class: Provitamin A (Carotenoid Antioxidant)

Overview

Beta-Carotene is a naturally occurring pigment found in plants and fruits, especially those that are orange or yellow in color. It is a precursor to vitamin A, meaning your body can convert it into vitamin A as needed. Beta-Carotene is used as a dietary supplement to prevent or treat vitamin A deficiency and to support eye health, immune function, and skin health. Beta-Carotene works by providing a source of vitamin A, which is essential for vision, growth, immune system function, and maintaining healthy skin and mucous membranes. Unlike preformed vitamin A, Beta-Carotene is considered safer because the body only converts as much as it needs, reducing the risk of toxicity. Key points for patients: Beta-Carotene is available over the counter and is generally well tolerated. However, high doses may not be safe for everyone, especially smokers or those with certain health conditions. Always consult your healthcare provider before starting any supplement.
