B-Complex vitamins are known to play a role in the function of the cardiovascular, pulmonary, and central nervous systems. At least four vitamins, B1 (Thiamine), B2 (Riboflavin), B3 (Niacin), and B5 (Pantothenic acid), may be essential to the body’s production of energy by aiding the metabolism of carbohydrates, fats and proteins. Folic acid and Vitamin B12 may help support red blood cell production. Folic acid also may help support a baby’s healthy growth and development, and the health of women of childbearing age. B-vitamins help many enzymes to perform essential chemical reactions, such as those that support the function of neurotransmitters, hormones, digestive enzymes, and many more.
