Vitamin B12 has a key role in normal function of the brain and nervous system and formation of red blood cells. It is involved in metabolism of every cell in the human body. Humans are not capable of producing vitamin B12 and therefore rely on supplementation. Excessive alcohol intake can decrease B12 absorption from the gastrointestinal tract, therefore intramuscular injection of B12 is a better route of supplementation.
Essential B Vitamins, including Vitamin B12, aid in cell growth & development, and breakdown of carbohydrates, fats, and alcohol. These B Vitamins are the building blocks for a healthy neurologic and cardio-vascular system.
