The vitamins are quickly and completely resorbed and a rapid therapeutic effect is attained in vitamin deficiencies.

Vitamin A enters the oxidation & reduction reactions, in special the Metabolism of carbohydrates & lipids, as well as it also stimulates the epithelia.

Vitamin D3 plays a role in Calcium & Phosphor metabolism and their precipitation in the bones helps both calcium & phosphor absorption in the intestine and stimulates parathyroid hormone.

Vitamin E regulates oxidation-reduction reactions & protein metabolism. it stimulates the urogenital tract.

Vitamin B1 is used in the synthesis of carboxylate yeast which is essential in amino acid metabolism. It has an important role in the transport of neural impulses by inhibition of cholinesterase function. 

Vitamin B2 is manufactured in the body by the intestinal flora. It turns into phosphoric acids which play a role in oxidation-reduction processes.

Vitamin B6 accesses the synthesis of many metabolic yeasts & amino acids.

Vitamin B12 is an erythrocyte maturation factor and it promotes metabolism.

Vitamin K3 helps in changing prothrombin into thrombin, so it prevents Haemorrhagia.
