Thiamine is a water-soluble vitamin. It belongs to the B vitamins. It can be obtained from pork, oatmeal, brown rice, vegetables, potatoes, liver, eggs, etc. Its main function is to act as a coenzyme in the generation of energy from carbohydrates. It is also involved in nucleic acid synthesis and in nerve function. Its derivative, thiamine pyrophosphate, is used in converting pyruvate to acetyl CoA. Inadequate thiamine in the diet leads to beriberi (a neurological and cardiovascular disease), optic neuropathy, and Wernicke-Korsakoff syndrome (with both neurologic and psychiatric symptoms). Quite the reverse, an overdose of thiamine may cause drowsiness or muscle relaxation.1 The Recommended Dietary Allowance for thiamin is 1.2 mg/day for adult males and 1.1 mg/day for adult females.2
