About B-Complex Vitamins B-Complex is a synergistic combination of all the essential B vitamins along with Choline, Inositol, and PABA, which are important co-factors that enhance the therapeutic benefits of B vitamins. Most commercially available B-Complex supplements provide a minimum of 100% DV of all the B Vitamins including B1 (Thiamine), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine), B9 (Folic Acid), and B12 (Methylcobalamin), along with Biotin, which is not technically a B Vitamin, but considered an important member of the B Vitamin family. Each member of the B Vitamin family is essential to promoting health in a crucial area of the body, including, but not limited to, the heart, nervous system, digestive system, immune system, metabolism, hormone production, and the development of genetic material. Nutritionists advise that in order to obtain the right amount of B-Complex vitamins for a balanced diet, one must have at least 5 daily servings of fruits and vegetables, as well as grains, which most do not consume in their everyday diets. Furthermore, all 8 components of the B-Complex family are very closely related in nature and work in an intense cooperative fashion to properly perform their essential functions within the body. Therefore, taking a B-Complex vitamin ensures that one is getting a complete and effective source of the essential B vitamins needed for a healthy life.
