Vitamin B-12 is a lot like a key, opening up doorways that lead to an array of metabolic and cellular processes.

B-12 works to form red blood cells, support immune system health, improve mood, protect the cardiovascular system, and maintain overall energy levels. Vitamin B12 injections are the most common way to prevent or treat a deficiency.
