Beta-carotene and other carotenoids provide approximately 50% of the vitamin A needed in the diet. It can be found in fruits, vegetables, and whole grains. The name beta carotene comes from the Greek "beta" and Latin "carota" (carrot). It is the yellow/orange pigment that gives vegetables and fruits their rich colors. H. Wachenroder crystallized beta carotene from carrot roots in 1831, and came up with the name "carotene". The 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. 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.
