Vitamin A

Aid Overall Health

Most people learn the importance of vitamins in grade school, but the benefits of vitamin A are not usually learned until adulthood. It was only a generation ago that details about vitamin A and its effects on the body warranted further study. Once the benefits were learned, products and supplements containing vitamin A soon hit the market by businesses that saw a way to capitalize on it.

This vitamin is produced in several forms that have an unstable molecular composition that is difficult to harness for supplementation. There are two forms that are directly consumed in food products, and used in vitamin A supplements.

These forms are retinols and carotenoids. Other molecules in the vitamin A group include retinyl and retinal or esters and aldehyde. The whole collection of the different variations of this molecular group is called retinoids.

People with vitamin A deficiencies display obvious symptoms of night blindness, brittle hair and nails as well as skin conditions at first, followed by the breakdown of other bodily functions. The good thing is the body’s ability to store vitamin A reserves. When vitamin A is synthesized in the liver, the time released retinol serum is managed before its final distribution to the blood cells.

Under-developed countries have populations of people with vitamin A deficiencies. Alcoholics suffer from this deficiency since retinol is a form of alcohol. The transformation process of retinol to retinoic acid in the presence of drinking alcohol is an effect. Another way the body is deprived of this nutrient is through lack of absorption. Your doctor should be able to find the reason for limited absorption.
