Each film-coated tablet contains Thiamine Mononitrate USP (Vitamin B1) 100 mg, Pyridoxine Hydrochloride BP (Vitamin B6) 200 mg, Cyanocobalamin BP (Vitamin B12) 200 mcg.
Vitamin B1 (Thiamine) forms thiamine pyrophosphate by combining with adenosine triphosphate; essential coenzyme in carbohydrate metabolism. Vitamin B6 (Pyridoxine) is a water-soluble vitamin which functions in the metabolism of carbohydrates, proteins and fats. It is essential in Hb formation and GABA synthesis within the CNS. Vitamin B12 (cobalamin) is a water-soluble vitamin that has a key role in the normal functioning of the brain and nervous system, and the formation of red blood cells. It is involved in the metabolism of every cell of the human body, especially affecting DNA synthesis, fatty acid and amino acid metabolism. Vitamin B1 (Thiamine), B6 (Pyridoxine) & B12 (Cyanocobalamin) play essential role as co-enzyme for the metabolism of nervous system. Thus this combination normalizes the nerve cell metabolism. This combination supports the regeneration of nerve fibers and myelin sheath by activation of the metabolism and the natural repair mechanism. The combination of these 3 vitamins shows better efficacy than that of the individual components. In addition, Vitamin B1, B6 & B12 promote body’s own repair mechanism and work in pain management.

Thiamine excretes into breast milk. Vitamin-B6 and Vitamin-B12 have no adverse effect or side during lactation.
Cyanocobalamin should not be given before a diagnosis has been fully established because of the possibility of masking symptoms of subacute degeneration of spinal cord. Cyanocobalamin is not a suitable form of Vitamin B12 for the treatment of optic neuropathies associated with raised plasma concentrations of cyanocobalamin.
