1. A word of introduction

Vitamin A is a group of organic chemicals that belong to the family of retinoids. To determine the amount of vitamin A in food, the most important of these is retinol and its derivatives. Certain carotenoids, including β-carotene, may be the source of Vitamin A. Β-Carotene is the most potent precursor to vitamin A. When supplied with food, it is converted into retinoid. In order to determine how much vitamin A is present in food it is also necessary to take into account the balance of the retinoil and the vitamin in the eggs made from β- carotene products.

2. Where does it apply?

Vitamin A is used as a daily supplement in the diet. It increases the strength of bones and teeth. The retinol mentioned above affects the skin, nails and hair, so it is very often found in many cosmetic products.

3. It works in the human body

Vitamin A has antioxidant and regenerative properties. Its main properties include: regulating the functioning of the visual organ and the growth of bones and teeth, strengthening of the skin and its derivatives (skin, hair, nails), proper function of the immune system, participation in protein metabolism, supporting RNA production, use in the prevention of cancer, protection of the respiratory tract from microbes.

4. Supplementation and deficiency symptoms
