B vitamins are easily lost from foods in refining and cooking. They can also be washed from the body by coffee, tea, alcohol and heavy perspiration. Physically stressful conditions can also deplete the body of B vitamins so it is essential to replenish your supply.
B-Vitamins are particularly important for the nervous system and for healthy digestive function and enzyme reactions that control energy, circulation, hormones and overall health. Their actions are interdependent, so for maximum efficiency, it is recommended to take a complex formula.
