Super B100 contains eight rich sources of B vitamins. All B vitamins help the body convert food (carbohydrates) into fuel (glucose), which is used to produce energy. These B vitamins, often referred to as B complex, also help the body metabolize fats and protein. B complex vitamins are needed for healthy skin, hair, eyes, and liver. They also help the nervous system function properly, and are needed for good brain function. The eight vitamins that make up the B complex are water soluble, meaning the body does not store excess amounts, with the exception of vitamin B12, which is stored in the liver. Rather, unused B vitamins are excreted through urine. This means you need a continuous supply of the B vitamins from the diet.*
