Vitamin A and Human Health: What’s the Latest Research?

Description

"Vitamin A is not one single compound. Rather, it is the name given to a group of fat-soluble compounds including retinol, retinoids (metabolites of retinol) and provitamin carotenoids.

As the human body does not make vitamin A, there are two main forms that can be obtained through the diet: preformed vitamin A (retinol and retinyl esters) consumed through animal products, and provitamin A carotenoids, consumed through plant-based materials, which are converted to retinol."
