All of the B vitamins are water soluble and so cannot be stored in the body. Each vitamin is chemically different from the others and all have separate functions in the body. The overall action of the complex is to help maintain health particularly of the nervous system. B vitamins are vital for carbohydrate, fat protein metabolism and the conversion of food to energy. They help maintain clear eyes, healthy looking skin and healthy hair. This probably is the reason so many women take a B Complex supplement as part of a nutritional daily beauty care programme. Suitable for vegetarians and vegans.
