Vitamin B1 travels through the bloodstream when consumed. Any unused thiamine exits the body through urine, with a small amount stored in the liver. Vitamin B1 has a short half-life. Therefore, humans must have a constant supply of it to have a sufficient intake.

  • Food and Nutrition: Thiamine helps the body break down food and turn it into energy. It also keeps the nervous system healthy. Nutraceutical companies in the food industry sell thiamine supplements. In many cases, vitamin B1 appears in multivitamin formulas. B-complex supplements include B vitamins such as thiamine that enhance brain and digestive function. Thiamine enhances supplement formulas for vegetarians using daily multivitamins. It also comes in the form of standalone thiamine supplements. Common types of thiamine included in nutraceuticals include thiamine mononitrate and thiamine hydrochloride. Some supplements contain the synthetic thiamine derivative benfotiamine.
  • Pharmaceutical: Thiamine is used for AIDS and boosting the immune system, diabetic pain, heart disease, alcoholism, aging, a type of brain damage called cerebellar syndrome, canker sores, vision problems such as cataracts and glaucoma, motion sickness, and improving athletic performance.
