What is retinol?

It is the form of vitamin A that our body produces in the intestine from animal sources. Retinol is the main form of vitamin A in human diets.

Vitamin A can also be obtained from the so-called vitamin A precursors, that is, from plant carotenes (alpha carotene, beta carotene and gamma carotene), and from xanthophyll beta-critoxanthin.

The human body converts these precursors into retinal (retinaldehyde)  which, in turn, also becomes retinol.
