The Basic Guiding Of Vitamin A

Vitamin A guidelines

Vitamin A is the group of fat-soluble nutrient compounds including retinol, retinal, and retinyl esters. That is found in animals as well as plants. It’s stored in body tissue for later use. Most vitamin A kept in our liver in the form of retinyl esters. These esters are then broken down into all-trans-retinol, which binds to retinol-binding protein (RBP). It then enters your bloodstream, at which point your body can use it. Let’s read the basic guiding of vitamin A


Preformed vitamin A (retinol and retinyl esters) that occurs only in animal products, such as dairy, liver, and fish

Provitamin A (carotenoids) are abundant in plant foods like fruits, vegetables, and oils.

To use them, our body must convert both forms of vitamin A to retinal and retinoic acid, the active forms of the vitamin.
