Vitamin B12 (1000 mcg vial)

Vitamin B12 (1000 mcg vial)

(Cobalamin — commonly methylcobalamin or cyanocobalamin)

Primary use: Energy metabolism and red blood cell support

Mechanism / class: Essential water-soluble vitamin; cofactor in DNA synthesis and methylation pathways

Key effects:

• Supports red blood cell production

• Essential for neurological function and myelin integrity

• Facilitates DNA synthesis and cellular replication

• Involved in methylation and homocysteine metabolism

• Supports energy production via mitochondrial pathways

Clinical distinction:
Not a peptide and not hormonally active; functions as a nutritional cofactor required for normal cellular metabolism. Unlike stimulants, it does not directly increase energy — it restores metabolic efficiency in deficient individuals. Benefits are most pronounced when deficiency is present.
