Medical Overview
Vitamin B12 is listed as Vitamin / Mineral containing Cyanocobalamin. A medicine used according to its active ingredient, dosage form, and the patient’s condition.
Vitamin B12 deficiency hides behind masks — fatigue, glove-and-stocking numbness, memory fog, low mood — often before macrocytic anemia appears. Silent depleters: metformin, chronic PPIs, veganism (no reliable plant source), gastric surgery, age. Pernicious anemia means lifelong injections; neuro recovery takes months; always check B12 before folate-treating a macrocytic anemia.
