Thiamine, also known as vitamin B1 and called aneurin, was the first vitamin to be discovered. Intestinal absorption of thiamine occurs mainly in the jejunum, by carrier-mediated active transport at low concentrations, and by passive diffusion at higher concentrations. Past research indicates that intestinal absorption of thiamine occurs for only a small percentage of a high oral dose and declines at intakes above 5 mg. Thiamine is carried in erythrocytes and plasma. The biological half-life is estimated to be nine to 18 days, and the average adult body contains approximately 30 mg. Urinary excretion increases when serum levels elevate and decreases when serum levels are lower.
Thiamine deficiency is a current and real problem among patients who are severely malnourished, particularly chronic alcoholics. If untreated, severe thiamine deficiency can progress to permanent brain damage or death. Ongoing knowledge of recent findings regarding thiamine can help RDs to be successful in the prevention of deficiency, identifying those who are at risk, and helping ensure appropriate treatment.
Thiamine is vitamin B1. Vitamins are naturally occurring substances necessary for many processes in the body. Thiamine is important in the breakdown of carbohydrates (sugars) in the foods we eat into products needed by the body.
Thiamine plays an important role in the body’s metabolism of carbohydrates. The horse’s body requires thiamine to produce erythrocyte transketolase, an essential enzyme for energy utilization. Thiamine has also been studied for its effect on the maintenance of healthy appetite and nervous system stability and poise. Thiamine is highly vulnerable to the heat generated in feed processing. Bracken fern, yellow star thistle, and horsetail contain substances that promote thiamine deficiency if eaten. Horses should be prevented from grazing these plants whenever possible.
Thiamine is a very important vitamin that provides many benefits. This article discusses these benefits and what the sources of it are.
Thiamine is a water soluble vitamin so if you take it in a pill form it will digest easily in your system. The body stores thiamine in certain parts of the body like the heart, brain and liver.
Thiamine deficiency in dogs is a disorder with a positive prognosis if it’s treated promptly. Owners of dogs who eat a lot of raw fish might not suspect that their pets are at high risk for developing this condition.
Thiamine (or B1) supports health and proper brain functioning. Although most individuals are at a low risk for deficiency, some conditions (including alcoholism) can contribute to it.
Thiamine was first discovered in 1910 by Umetaro Suzuki in Japan when researching how rice bran cured patients of beriberi . He named it aberic acid . Suzuki did not determine its chemical composition, nor that it was an amine.
Thiamine triphosphate (ThTP) was long considered a specific neuroactive form of thiamine. However, recently it was shown that ThTP exists in bacteria , fungi , plants , and animals , suggesting a much more general cellular role. In particular, in Escherichia coli it seems to play a role in response to amino acid starvation.
Thiamine is found naturally in the following foods, each of which contains at least 0.1 mg of the vitamin per 28-100g (1-3.5oz): green peas , spinach , liver , beef , pork , navy beans , nuts , pinto beans , soybeans, whole-grain and enriched cereals , breads, yeast , and legumes .
