B vitamins are readily depleted in the body when you are under extra stress, when you are sick or fighting illness, during periods of intense exercise or when you are exposed to pollutants, such as cigarette smoke or smog. During such times, your body systems require extra energy for optimal function and to keep you healthy. B-complex provides the support for energy production by all cells.
