Absorption thiamine in the daily diet through the digestive tract due to the active transport of Na + dependent. When thiamine concentrations in the gastrointestinal tract highly passive diffusion is also important. However, high-dose absorption is limited. After intramuscular, thiamin is also rapidly absorbed, distributed in most tissues and milk. In adults, approximately 1 mg of thiamine is completely degraded every day in the tissues, and this is the minimum amount needed daily. When this low absorption, with little or no see thiamin excretion via urine. When absorbed exceeds the minimum requirements, the storage of thiamine in the first tissue saturation. Then the excess will be excreted in urine as intact molecules thiamin. When absorbed further increased thiamin, thiamine excreted less than transformation will increase.
