Vitamin A is also known as retinol or axerophtol and it belongs to the group of fat-soluble vitamins. It is found mainly in foods of animal origin (especially in the liver). In plants it is in the form of a provitamin – beta-carotene and other carotenoids compounds.
Vitamin A was discovered and chemically defined in 1931, and from 1947 it is produced industrially.
Axerophtol prevents 'nyctalopia', the weakening of eyesight, helps in the treatment of many eye diseases. It is part of rhodopsin, a dye located in the retina. The vitamin A also has a positive effect on the look of skin, hair and nails. Influences on the synthesis of protein, lipid and steroid hormones. It maintains the good condition of the mucous membranes of the mouth, nose, throat, lungs.
The vitamin A is essential for the synthesis of steroid compoinds, sex hormones in particular. It is involved in the regulation of gene expression.
If you decide to start a vitamin A supplementation, remember the following:
- the vitamin E and zinc facilitate the use of the delivered dose of the vitamin A
- the vitamin A should be taken with food, because fat enhances its absorption
- the vitamin A helps in the absorption of iron from food
Vitamin A is an optimal dose. Deficiencies of this vitamin cause skin problems (hyperkeratosis of the epidermis), dried conjunctivitis, eye problems, liver disease. The product is formulated so that one capsule covers the daily requirement of vitamin A. It dissolves in fat, so I recommend taking it with the main meal containing fat. Vitamin A supplementation should be combined with vitamin D3 and K2. They work synergistically and help to keep the body in perfect condition. Very good combination is also taking vitamin A together with vitamin E. One in four men and one in three women suffer from deficiencies of these two vitamins. Deficiencies must be supplemented. You should also take care of maintaining the proper levels of these vitamins.

Retinyl palmitate - ester of vitamin A, especially valued in cosmetology. It is considered the gentlest form of this vitamin, therefore it is recommended to people with sensitive skin. It is also characterized by good assimilability in oral application, it is de-esterified without any problems in the small intestine to retinol, a fully active biological form of vitamin A.
Retinol demonstrates a wide range of activities in the human organism. Vitamin A is especially popular due to its positive influence on epithelial cells. It is responsible for proper, nourished state of skin, hair and nails. Apart from this, proper supply of retinol is also incredibly important for the health of the skeletal system, as vitamin A is a regulator of growth of bone tissue.
Vitamin A is also essential to maintain proper functions of eyesight. Its derivative, by binding with opsin, creates rhodopsin, which is responsible for stimulating the activity of rod cells located on eye retina. Thanks to this, it is possible to maintain proper vision in the conditions of poor lighting.
Some sources also suggest immunity functions of vitamin A. It may decrease the risk of pathogen permeation in the epithelium of the respiratory system.
