Vitamin B1 is used for the metabolism of fats, carbohydrates, proteins, and sugars, for the production of energy in the body. It helps maintain a healthy nervous system and the normal functioning of the heart and other muscles. The more physical and mental activity the body undergoes, the more thiamine it needs. Stress increases the body's need for vitamin B1 (as with all B-complex vitamins).
