Introduction to Vitamin A

Popularly called Retinol, Vitamin A is fat-soluble alcohol and is widely found in fatty fish-liver oils. Vitamin A is also found in milk fat, eggs, and other such healthy items. You won't find Vitamin A in plants, but you will find it in vegetables and fruits. So is why doctors highly recommend consuming fruits and vegetables on the regular basis. After consumption of fruits and vegetables, vitamin A gets destroyed upon exposure to heat, light, or air. Vitamin A, functioning directly in vision, gets converted into retinaldehyde, which is an essential part and is present in the retina of the eye. Vitamin A, in the form of retinoic acid, is combined with specific proteins, and functions in the regulation of embryonic development and growth. This acid is also vital for the maintenance of the epithelial tissues for sperm formation and functioning of the immune system.

In general, we humans require Vitamin A in a small amount. The recommended intake on the regular basis is 1000 and 800 micrograms. Most of the Vitamin A gets stored in the liver area in the form of retinal esters. These esters then break into all-trans-retinol and enter into your bloodstream, so that our body can use it for functioning.
