It is found in many B complex products. It is a water soluble vitamin that plays an important role in maintaining healthy functioning of nerves, muscles and heart.



  • Vitamin B1 acts as coenzyme in the form of thiamine pyrophosphate (TPP). It activates other enzymes and proteins that control several biochemical processes occurring in the body. TPP is needed to release energy from fats, carbohydrates and protein metabolism.
  • It plays an important role in maintaining healthy nervous system. The non-coenzyme functions of thiamin are important for nerves as well as muscles. TPP plays an important role in conduction of nerve impulses and in metabolism of adrenalin, serotonin and acetylcholine.
  • It is also known as anti-stress vitamin, as it improves the immune system of the body and increases its ability to withstand stressful conditions.
  • It is also used as a coenzyme in chemical reactions which produces many prominent compounds, such as ATP, NADPH and RNA and DNA.
