Table of Contents
1. Vitamin A properties
Vitamin A has a very beneficial effect on vision because it is a component of rodopsin, which is the photosensitive pigment of the retina of the eye that allows you to see after dark. Without this vitamin, the metabolism of proteins and steroid hormones would be impossible. It is involved in the proper course of cell growth processes and in the differentiation of cells in the body.2. Causes and effects of shortages
Many people think that carrot is a good source of vitamin A. This is not true. It contains beta-carotene, or so-called pro-vitamin. The body itself has to process beta carotene. Unfortunately, beta-karotene is absorbed in only 2050%. It is also not processed in a 1:1 ratio, but about 1:61:48. Vitamin A deficiency can occur in people with diabetes and people with problems with the functioning of the pancreas. People with a low memory gallbladder can also have problems with a shortage of blood cells.3. Effects of excess
It is important to remember that vitamin A can be overdosed. Hypervitaminosis can be triggered by irritability, disorders of the digestive tract such as vomiting, lack of appetite or nausea. It can cause skin discoloration and very dangerous enlargement of the liver and spleen.4. Where to look for her
