identifies a group of water soluble vitamins that are not stored
in the body in signifcant quantities. Since it normally flushes
out of the body quickly, it must be ingested on a daily basis. It
plays a role in numerous chemical processes inside the body. It
is also known as thiamine, thiamin and aneurin.
Vitamin B1 is required for the processing of
carbohydrates, fat, and protein, and using them to create energy
in the form of ATP. Nerve cells also need vitamin B1 for normal
functioning. Thiamin also promotes good circulation and supports
normal cognitive brain function. It also functions as an antioxidant,
guarding the body from the damaging effects of free radicals. Thiamin
deficiency can happen due to a number of factors, including severe
dieting, alcoholism, liver disease, and kidney dialysis. People
who ingest large amounts of sugary foods, soft drinks, and processed
foods may also have an elevated risk of deficiency. Read more about

Vitamin B1 can be obtained from a wide variety
of foods, including fortified bread, cereals, and pastas, whole
grains, pork, fish, eggs, peas, beans, and soybeans. Dairy products,
vegetables and fruits do not contain large amounts of vitamin B1,
but can supply significant amounts when eaten in larger quantities.

Thiamin is a water-soluble nutrient, and thus,
is difficult to ingest in levels which are toxic. Risk of vitamin
B1 toxicity through diet is very low.. However, when taken via an
injection, there have been a small number of reported cases of anaphylactic
shock. Read more about vitamin
Vitamin B1 is a water-soluble vitamin composed
of a substituted pyrimidine ring connected by a methylene bridge
to a substituted thiazole ring. In the body, the vitamin B1 is found
in the largest amounts in the muscles, heart, brain, liver, and
kidneys. Vitamin B1 exists in food souces as three types: free form
thiamin, thiamin pyrophospate (TPP) and as a protein phosphate complex.
Vitamin B1 can be produced in the large intestine
as thiamin pyrophosphate (TPP). The primary circulating type of
the vitamin is thiamine diphosphate (TDP) which is located nearly
exclusively in the red blood cells. The TPP molecule is too big
to be absorbed via the intestinal lining. It needs to use an enzyme
to separate the smaller thiamin molecule from the compound. TDP
is a cofactor for a number of different enzymes: pyruvate dehydrogenase,
transketolase, and thiamine triphosphate, which is believed to be
vital for nerve conduction.
Vitamin B1 can be found in supplements as both
thiamin hydrochloride and thiamin nitrate. These types are also
the ones utilized to fortify foods. Thiamin pyrophosphate or cocarboxylase
can also be found in certain products.
Vitamin B1 helps prevent beriberi. Breads,
flours and cereals are regularly fortified with thiamin so there
is little chance of a deficiency for most people, which results
in little risk of beriberi.
