Vitamin B12

An essential vitamin required for red blood cell formation, neurological function, and cellular energy metabolism.

Clinical Profile

Vitamin B12 (cobalamin) is essential for DNA synthesis and the maintenance of the myelin sheath around nerves. Methylcobalamin is considered one of the most bioavailable and readily utilized forms for supplementation, compared to synthetic cyanocobalamin.

Clinical Summary

Widely supported by clinical literature, particularly for correcting deficiency-related fatigue and neurological symptoms; especially relevant for individuals with genetic methylation variants (e.g. MTHFR).

Dosage Guidelines

500mcg to 1,000mcg daily for general supplementation; higher doses may be used clinically for diagnosed deficiency.

Safety & Side Effects

Extremely well tolerated even at high doses due to water solubility; excess is excreted in urine.

Known Interactions

May reduce the effectiveness of metformin over long-term use; limited other significant interactions.
