What role do B vitamins play in the human body?

There is no single Vitamin B. It is divided into many other vitamins, all of which form the group called the B vitamins.

Vitamin B12-brain development, and DNA synthesis for cell regeneration

Niacin- skin, nervous system, and mental performance

Folic acid-Red blood cell formation, metabolizes fats, amino acids, protein synthesis

Vitamin B2-skin, eyes and energy

Vitamin B1- functioning of nervous system, appetite, and energy

biotin- for hair growth and protein synthesis

pantothenic acid- functioning of various glands in the body

Vitamin B6- helps metabolize fat and protein and is needed to make red blood cells

Interesting fact: Vitamin B12 is the one that is most missing in vegan diets, because it is mostly found in animal sources. However, foods like tofu, tempeh, and Seitan provide B12.
