why beta carotene supplements is good for you
Beta-carotene in itself is not an essential nutrient, but vitamin A is. Vitamin A can be sourced from the food we eat, through beta-carotene, for example, or in supplement form. The advantage of dietary beta-carotene is that the body only converts as much as it needs. Excess vitamin A is toxic.he human body converts beta-carotene into vitamin A (retinol) - beta-carotene is a precursor of vitamin A. We need vitamin A for healthy skin and mucus membranes, our immune system, and good eye health and vision.
