The B vitamins often work together to deliver a number of health benefits to the body. B vitamins have been shown to: Support and increase the rate of metabolism; Maintain healthy skin and muscle tone; Enhance immune and nervous system function; Promote cell growth and division — including that of the red blood cells that help prevent anemia; Reduce the risk of pancreatic cancer, one of the most lethal forms of cancer, when consumed in food, but not when ingested in vitamin tablet form. 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. Most of the B vitamins must be replenished daily, since any excess is excreted in the urine.

Niacin, also known as nicotinic acid or vitamin B3, is a water-soluble vitamin discovered by Conrad Elvehjem in 1937. Its derivatives, NADH, NAD, NAD+, and NADP play essential roles in energy metabolism in the living cell and DNA repair (an enzymatic process in a living cell). The designation vitamin B3 also includes the corresponding amide nicotinamide (or "niacinamide"), whose chemical formula is C6H6N2O. Other functions of niacin include removing toxic chemicals from the body, and assisting in the production of steroid hormones made by the adrenal gland, such as sex hormones and stress-related hormones.
