Healthy Eating & Vitamin A
Vitamin A is a group of compounds that form a fat soluble vitamin stored mainly in the liver. It helps regulate the immune system as well as contributing to healthy vision, bone growth, reproduction and the functioning of cells within the body.
There are two forms of vitamin A: preformed vitamin A| which is found in food that comes from animals and is absorbed in the form of retinol, and provitamin A carotenoid which comes from fruit and vegetables and is converted into retinol in the body. Retinol is one of the most usable forms of vitamin A. The recommended daily allowance of vitamin A is 800mg or 5000 IU (international units). The upper limit recommended allowance is 2300mg / 20,000 IU.
