Methylcobalamin is a naturally active form of vitamin B12 essential for maintaining neurological function and red blood cell production. It supports nerve regeneration and enhances myelin synthesis, aiding in the treatment of peripheral neuropathy, diabetic nerve pain, and neurodegenerative conditions such as Alzheimer’s disease. This bioavailable form of B12 also contributes to DNA synthesis, energy metabolism, and cognitive function, while helping lower homocysteine levels to promote heart health. Methylcobalamin is often preferred over synthetic cyanocobalamin due to its higher absorption efficiency and direct availability for cellular utilization.
