Biotin (Vitamin B7) is essential for the proper course of myelin synthesis (axon sheath) and plays an important role in obtaining energy for nerve cells. In addition, it protects the circulatory system, prevents atherosclerosis, improves the condition of the skin, hair and nails. About 45% of myelin’s lipids are phospholipids, they are: plasmalogens, phosphatidylserine, phosphatidylinositol, phosphatidylcholine and phosphatidylethanolamine. Biotin is a coenzyme of acetyl-CoA carboxylase and it participates directly in the synthesis of fatty acids (KT). It has been proven that vitamin H deficiency determines a drastic decrease in the level of phospholipids in cell membranes and contributes to disturbances in the functioning of myelin synthesizing enzymes. This is associated with loss of muscle coordination, lack of ability to absorb information or the occurrence of epilepsy. It was found that daily administration of highly concentrated biotin to people suffering from multiple sclerosis (300 mg / day, for 9 to 36 months) may significantly improve the degree of their disability in the EDSS scale (extended scale of Kurtzki’s failure). Vitamin B7 is soluble in water, so it is best to use it without a meal. However, it is important to dose biotin at higher doses than recommended, when consuming large amounts of eggs, because they are rich in protein – avidin, which inactivates and prevents the absorption of this vitamin, contributing to its deficiency in the body.
