Vitamin B1, also known as thiamin, helps fuel your body by converting blood sugar into energy. It keeps your mucous membranes healthy and is essential for nervous system, cardiovascular and muscular function. Nutritionists categorize vitamins by the materials that a vitamin will dissolve in. There are two categories: water-soluble and fat-soluble vitamins. Water-soluble vitamins, which include the B-complex group and vitamin C, travel through the bloodstream. Whatever water-soluble vitamins are not used by the body are eliminated in urine, which means you need a continuous supply of them in your food. Vitamin B1 is a water-soluble vitamin.
