Is beta-carotene and vitamin A the same thing?

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.

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. (1)
