What is Vitamin B1?

Vitamin B1, the preferred name for vitamin B1, is a heat-labile and water-soluble essential vitamin, belonging to the vitamin B family, with antioxidant, erythropoietic, mood modulating, and glucose-regulating activities. Thiamine reacts with adenosine triphosphate (ATP) to form an active coenzyme, thiamine pyrophosphate. 

Vitamin B1 is necessary for the actions of pyruvate dehydrogenase and alpha-ketoglutarate in carbohydrate metabolism and for the actions of transketolase, an enzyme that plays an important role in the pentose phosphate pathway. Thiamine plays a key role in intracellular glucose metabolism and may inhibit the action of glucose and insulin on arterial smooth muscle cell proliferation. Vitamin B1 may also protect against lead toxicity by inhibiting lead-induced lipid peroxidation.

Thiamine chloride Uses And Synthesis

Thiamine, the preferred name for vitamin B1, holds a prominent place in the history of vitamin discovery because beriberi, the disease resulting from insufficient thiamine intake, was one of the earliest recognized deficiency diseases.

Thiamine chloride Clinical Use

Thiamine chloride, as the base or as the hydrochloride salt, is indicatedin the treatment or prophylaxis of known or suspected thiaminedeficiencies. Severe thiamine deficiency is calledberiberi, which is very rare in developed countries.
