Pharmacological action of Astymin

Amino acids are the basic building blocks of proteins and enzymes and are essential for normal healthy bodily function especially during growth and convalescence.  The essential amino acids cannot be made in the body and must be included in the diet or Vitamins as a supplement.

Vitamins B1, B2, B6 and nicotinamide are parts of co-enzyme systems concerned with release of energy from foodstuffs. Like the essential amino acids and minerals, they cannot be made in the body and must be included in the diet in small quantities. The B-complex vitamins are water-soluble and are not stored in the body in appreciable amounts. Consequently, regular replenishment of these vitamins is required. Their presence prevents the development of certain deficiency diseases such as beri-beri, riboflavinosis and pellagra.
