B1 (thiamin), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate [folic acid]), and B12 are the eight B vitamins (cobalamin). According to Rosanna Sutherby, PharmD, "each of the B vitamins serves a unique function for your body and health."
They aid in the function of the nervous system by coating nerve cells so that they can function properly. They help you convert food into energy. Some of them aid in the absorption of other vitamins. They aid in digestion and muscular tone. They produce red blood cells that transport oxygen to your organs via the bloodstream.
Folate is essential for a healthy pregnancy. "All women of childbearing age should take 400 micrograms of folic acid daily," says Dr. Sutherby. "You need 600 to 1,000 micrograms of folic acid daily during pregnancy. Folate helps a baby's brain and spine develop. Vitamin D helps prevent birth defects if taken before and during pregnancy.
Thiamin converts nutrients into body energy. Thiamine may strengthen the immune system and the body's ability to withstand stress, according to Mount Sinai Health. B1 is the first B vitamin discovered. Thiamine is found in plants and animals and helps with metabolic reactions. Every cell in your body uses adenosine triphosphate (ATP) for energy.
B12 helps nerves and the brain. Vitamin B12 is found in animal foods. It's added to foods and supplements. Red blood cells and DNA need B12. According to the Harvard T.H. Chan School of Public Health, it's important for brain and nerve cell function and development.
B7 [Biotin] boosts metabolism. Dr. Sherry Ross, OB/GYN and Women's Health Expert at Providence Saint John's Health Center in Santa Monica, California, says biotin benefits the skin, nerves, digestive tract, metabolism, and cells. Biotin is needed to form fatty acids and glucose, which provide energy.
