Ultra-High Potency multi B vitamin for busy lifestyles and stress - Radiance B100 Complex is a super strength vitamin B complex formula indicated for those under stress, inadequate dietary intake, performance athletes, nervousness or neurological symptoms, or showing other signs of deficiency. B vitamins function in many different ways to help enzymes carry out thousands of molecular conversions in the body. All B vitamins are water-soluble substances, so they are not stored in the body in any great quantity. B vitamins are all sensitive to heat, light, processing, milling, preservatives and cooking. These factors, so common in a modern Western diet, deplete foods of these essential vitamins. B complex vitamins provide the body with energy. They are also vital in the metabolism of fats and protein, for the normal functioning of the nervous system, maintenance of muscle tone in the gastrointestinal tract, and the health of the skin, hair, eyes, mouth and liver.
