Megalob (500Mcg) 1Ml, 10 Ampoule Injections

Methylcobalamin, the active form of vitamin B12, exerts its therapeutic effects primarily through its role as a coenzyme in various enzymatic reactions. It plays a crucial role in the methylation of homocysteine to methionine, which is essential for DNA synthesis, neurotransmitter production, and the maintenance of myelin sheaths in the nervous system. Methylcobalamin promotes the regeneration of damaged nerve cells and enhances nerve conduction, thereby improving neurological function. It also supports the production of red blood cells and maintains the integrity of the myelin sheath, which is vital for optimal nerve function. By participating in these metabolic processes, methylcobalamin helps alleviate neurological symptoms, enhance nerve regeneration, and improve overall nerve health.
