B-complex vitamins are a group of important water-soluble vitamins with similar functions in the body. B-complex vitamins provide nutritive support for healthy hair and skin, nerve impulse transmission, immune system function and red blood cell formation. They also work together to aid in the metabolism of carbohydrates, fats and protein.
The vitamin B-complex refers to all of the known essential water-soluble vitamins except for vitamin C. These include thiamine (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), pantothenic acid (vitamin B5), pyridoxine (vitamin B6), biotin, folic acid and the cobalamins (vitamin B12).
“Vitamin B” was once thought to be a single nutrient that existed in extracts of rice, liver or yeast. Researchers later discovered these extracts contained several vitamins, which were given distinguishing numbers. Unfortunately, this has led to an erroneous belief among non-scientists that these vitamins have a special relationship to each other. Further adding to confusion has been the “unofficial” designation of other substances as members of the B-complex, such as choline, inositol and para-aminobenzoic acid (PABA), even though they are not essential vitamins.
Each member of the B-complex has a unique structure and performs unique functions in the human body. Vitamins B1, B2, B3 and biotin participate in different aspects of energy production, vitamin B6 is essential for amino acid metabolism, and vitamin B12 and folic acid facilitate steps required for cell division. Each of these vitamins has many additional functions.
