Vitamin BVitamin B is a complex of several vitamins. The name arises because it was once considered a single vitamin, much like Vitamin C or Vitamin D. Since later research has shown it is in fact a complex of chemically distinct vitamins that happen to often coexist in the same foods, the name has gradually declined in use, being replaced by the generic term "the B vitamins", the vitamin B complex, or by the specific names of each vitamin. The B vitamins are: Several other substances which are not human vitamins have been referred to as B vitamins. These include: In addition to coexisting in the same foods, the B vitamins often work together to bolster metabolism, maintain healthy skin and muscle tone, enhance immune and nervous system function, and promote cell growth and division — including that of the red blood cells that help prevent anemia. Together they also help combat the symptoms and causes of stress, depression, and cardiovascular disease. All B vitamins are water soluble, and are dispersed throughout the body and must be replenished daily with any excess excreted in the urine. Brewer's yeast is a good source of Vitamin B.
