Nutrifactor Vitamin B12 (500mcg) 60 Tablets

Vitamin B12 is crucial for the conversion of homocysteine to methionine, a process that is vital for DNA synthesis and repair. It acts as a cofactor for the enzyme methionine synthase, which is involved in this conversion. Methionine is then used to produce S-adenosylmethionine (SAMe), a compound that is important for methylation reactions throughout the body, including the regulation of gene expression and neurotransmitter production. Additionally, Vitamin B12 is necessary for the conversion of methylmalonyl-CoA to succinyl-CoA, a step in the metabolic pathway that helps produce energy from fats and proteins. This pathway is also critical for the formation of myelin, the protective sheath around nerve fibers, which is essential for proper nerve function. In summary, Vitamin B12 plays a key role in DNA synthesis, energy production, and maintaining nerve health by participating in critical biochemical reactions in the body.
