Vitamin B-9, or folate, is best known for its role in preventing spinal birth defects. It also plays roles in red blood cell function and in synthesizing the essential amino acid methionine, along with vitamin B-6, or pyridoxine, and B-12, or cobalamin. Vitamin B-6 also helps with the immune system and babies' brain development. The body uses vitamins B-1 (thiamine), B-3 (niacin) and B-5 (pantothenic acid) to help turn carbohydrates from food into glucose, the body's primary energy source. Vitamin B-2, or riboflavin, helps support red blood cell functioning, and vitamin B-7, or biotin, plays a role in synthesizing fats and proteins.
The B vitamins help the body use energy by breaking down carbohydrates into simple sugars and breaking down proteins and fats. Breaking down proteins and fats is particularly important for the health of the nervous system, and folic acid is important in the prevention of birth defects. Though B vitamins can be obtained from foods, some are synthesized in the gastrointestinal tract.
B vitamins are water soluble, which means the body uses as much of these vitamins as it needs and excretes the rest in the urine. However, some B vitamins are toxic if too much is taken at one time. The body stores some B vitamins in the liver.Learn more about Nutritional Content
