Vitamin H (biotin) is a water-soluble vitamin. Also it is known by name vitamin B7. It was isolated from egg yolk in 1936. It contains sulfur. Biotin is not decomposed by light or temperature increase. And it is not oxidized by atmospheric oxygen, but not resistant to ultraviolet radiation. In medicine, vitamin H is used in disorders of the nervous system, expressed in fatigue, depressed mood, irritability, and in the treatment of diseases of the head skin (hair loss, seborrhea).
Vitamin H has an influence on the exchange of carbohydrates and fats in the body, as well as the energetic processes. It promotes better digestion of protein. This vitamin enhances the action of group B vitamins, what is especially important in effect of biotin on skin, hair and nails. It’s because biotin takes part in the production of collagen, providing the skin elasticity.
This vitamin can be attributed to the "vitamins of beauty". It is particularly important to provide adequate intake of vitamin H in the body during stressful situations, since it is involved in maintenance of the necessary level of glucose in the blood. It supports the existence of beneficial micro flora in the bowels. It is important to support the adequate intake of biotin in the body during growth.
The consequences of this vitamin shortage are evident. In humans, deficiency of vitamin H is expressed in the dryness of the skin, nervous disorders, cracks on the lips and so on.
