Vitamin B1, also known as thiamin, helps fuel your body by converting blood sugar into energy. It keeps your mucous membranes healthy and is essential for nervous system, cardiovascular and muscular function.
Thiamin is a water-soluble B-complex vitamin. Thiamin was isolated and characterized in the 1920s, and thus was one of the first organic compounds to be recognized as a vitamin.
Nutritionists categorize vitamins by the materials that a vitamin will dissolve in. There are two categories: water-soluble and fat-soluble vitamins. Water-soluble vitamins, which include the B-complex group and vitamin C, travel through the bloodstream. Whatever water-soluble vitamins are not used by the body are eliminated in urine, which means you need a continuous supply of them in your food. Vitamin B1 is a water-soluble vitamin.
Thiamin is involved in numerous body functions, including: nervous system and muscle functioning; flow of electrolytes in and out of nerve and muscle cells (through ion channels); multiple enzyme processes (via the coenzyme thiamin pyrophosphate); carbohydrate metabolism; and production of hydrochloric acid (which is necessary for proper digestion). Because there is very little thiamin stored in the body, depletion can occur as quickly as within 14 days.
Severe chronic thiamin deficiency (beriberi) can result in potentially serious complications involving the nervous system/brain, muscles, heart, and gastrointestinal system.
Dietary sources of thiamin include beef, brewer's yeast, legumes (beans, lentils), milk, nuts, oats, oranges, pork, rice, seeds, wheat, whole grain cereals, and yeast. In industrialized countries, foods made with white rice or white flour are often fortified with thiamin (because most of the naturally occurring thiamin is lost during the refinement process).
- Nerve regulator
- At least 1.5 mg daily
- Natural sources: Beef, pork, pasta
Interactions & Side Effects
- Loop diuretics. You may need extra thiamin
- Thiamin is generally considered safe and relatively nontoxic, even at high doses. No clear tolerable upper level (UL) of intake has been established. Dermatitis or more serious hypersensitivity reactions occur rarely.
- Large doses may cause drowsiness or muscle relaxation.
- Injections of thiamin may cause burning. Reactions can often be avoided by slow administration into larger veins.
