What is it?

Sulfiteswhich are added to foods usually as a preservative, [34] will attack thiamine at the methylene bridge in the structure, cleaving the pyrimidine ring from the thiazole ring. Thiamine is degraded by thermolabile thiaminases present in raw fish and shellfish [12].

Some thiaminases are produced by bacteria. Bacterial thiaminases are cell surface enzymes that must dissociate from the membrane before being activated; the dissociation can occur in ruminants under acidotic conditions. Rumen bacteria also reduce sulfate to sulfite, therefore high dietary intakes of sulfate can have thiamine-antagonistic activities.

Plant thiamine antagonists are heat-stable and occur as both the ortho- and para-hydroxyphenols. Some examples of these antagonists are caffeic acidchlorogenic acidand tannic acid. These compounds interact with the thiamine to oxidize the thiazole ring, thus rendering it unable to be absorbed.

Two flavonoids, quercetin and rutinhave also been implicated as thiamine antagonists. Food fortification Refining grain removes its bran and germ, and thus subtracts its naturally occurring vitamins and minerals.

In the United States, B-vitamin deficiencies became common in the first half of the 20th century due to white flour consumption. The American Medical Association successfully lobbied for restoring these vitamins by enrichment of grain, which began in the US in The UK followed in and Denmark in At low concentrations, the process is carrier-mediated.

At higher concentrations, absorption also occurs via passive diffusion. Active transport is greatest in the jejunum and ileum, but it can be inhibited by alcohol consumption or by folate deficiency.

A specific binding protein called thiamine-binding protein TBP has been identified in rat serum and is believed to be a hormone-regulated carrier protein important for tissue distribution of thiamine.

Usual Adult Dose for Beriberi

ThMP and free unphosphorylated thiamine is present in plasma, milk, cerebrospinal fluidand, it is presumed, all extracellular fluid.For adults with somewhat low levels of thiamine in their body (mild thiamine deficiency): the usual dose of thiamine is mg daily in either a single dose or divided doses for one month.

Thereafter, use an oral therapeutic multivitamin preparation containing 5 to 10 mg thiamine daily for one month. A complete and balanced diet should follow.

If response to thiamine, continue with mg IV or IM once daily for an additional 3 to 5 days (or until clinical improvement ceases) followed by 30 mg orally twice daily thereafter (Sechi ) or mg orally 3 times daily for 1 to 2 weeks followed by mg orally once daily thereafter (Latt ).

The average daily thiamin intake from foods and supplements in children and teens is mg for ages 2–5 years, mg for ages 6–11 years, and mg for ages 12–19 years. In adults aged 20 and older, the average daily thiamin intake from foods and supplements is mg in men and mg in women.

Thiamine is found in foods such as cereals, whole grains, meat, nuts, beans, and peas. Thiamine is important in the breakdown of carbohydrates from foods into products needed by the body.
