Each B vitamin is essential to certain bodily functions:
B1 and B2 are important for healthy functioning of the muscles,
nerves, and heart;
B3 helps regulate the nervous and digestive systems;
B5 and B12 are required for normal growth and development;
B6 supports the immune system and aids the body in breaking down protein;
Studies show that taking supplements containing certain B vitamins may benefit
your health. For instance, B1 may help prevent kidney disease in people with
type 2 diabetes and reduce risk of cataracts;
B2 may prevent migraines;
B3 may lower cholesterol levels;
B6 may protect against heart disease, relieve PMS symptoms, and alleviate
pregnancy-related nausea;
B12 may lower cervical cancer risk and reduce levels of homocysteine
(an amino acid thought to contribute to heart disease when it occurs at
elevated levels).
