Back to all nutrients Vitamin B1, also known as thiamin, is a water-soluble B vitamin that occurs in the human body as free thiamin and as various phosphorylated forms: thiamin monophosphate (TMP), thiamin triphosphate (TTP), and thiamin pyrophosphate (TPP). Vitamin B1 was the first vitamin identified in 1926. Thiamin pyrophosphate (TPP), synthesized from free vitamin B1 (thiamin), requiring magnesium, acts as coenzyme for a small number of very important enzymes (e.g., pyruvate dehydrogenase). Some preliminary evidence suggests that vitamin B1 (thiamin) ─ along with other micronutrients such as vitamin A and vitamins of the B complex (B2, B9, B12) ─ may protect the eyes’ lens and lower risk of getting cataracts. Things to know about Vitamin B1 Wernicke-Korsakoff syndrome is a brain disorder caused by vitamin B1 (thiamin) deficiency. Because vitamin B1 (thiamin) facilitates energy utilization, requirements are tied to energy intake, which can be very much dependent on activity levels.
The recommendations are based on an average caloric intake. National nutrition surveys in European countries provide an indication of current intake of some B vitamins. Vitamin B1 (thiamin) deficiency affects the cardiovascular, nervous, muscular, and gastrointestinal systems. Whole grain cereals, legumes (e.g., beans and lentils), nuts, lean pork, and yeast are rich sources of vitamin B1 (thiamin) (2). To date, no well-established toxic effects from the consumption of excess thiamin in food or through long-term oral supplementation (up to 200 mg/day) are known (15, 20).

Food sources include whole grains, beans, nuts, sunflower seeds, pork and beef. Riboflavin (vitamijn B2) is a water-soluble vitamin involved in ATP production and the metabolism of many of the other B group vitamins. Food sources include almonds, mushrooms and wild rice. Vitamin B2 supplements may change urine colour to bright yellow.This is harmless and temporary.nicotinamide (vitamin B3) is a water-soluble nutrient involved in energy production and carbohydrate metabolism. Legumes, peanuts, wheat bran, and fish are all sources of vitamin B3.
Pantothenic acid (vitamin B5) is involved in the metaboloism of fats and carbohydrates for energy production. Vitamin B5 is found in sunflower seeds, peas, beans (except green beans), poultry and whole grains. Pyridoxine hydrochloride (vitamin B6) is a water-soluble nutrient involved in the production of proteins, neurotransmitters and haemoblobin. Whole grains, legumes, bananas, seeds, nuts and potatoes are good sources of vitamin B6. Cyanocobalamin (vitamin B12) is an essential water-soluble nutrient needed for protein and DNA synthesis, folate metabolism, and red blood cell production. Food sources of vitamin B12 include egg yolk, fish, beef, milk and cheese. Biotin is a water-soluble nutrient belonging to the B group vitamins. Food sources of biotin include cheese, cauliflower and eggs. Choline is a water-soluble nutrient that is related to the B group vitamins and plays a role in the metabolism of fats. Eggs, peanuts and soy beans are good sources of choline.
Inositol is a 'vitamin-like' substance related to the B group vitamins. It is a component of cell membranes and plays a role in transporting fats from the liver. A water-soluble B group vitamin, folate is involved in the synthesis of DNA and RNA and the activation of vitamin B12 into it's active form. Folic acid is found in fresh green leafy vegetables, broccoli, mushrooms, legumes, nuts and fortified cereals. Adults – Take 1 tablet a day with a meal, or as professionally prescribed.

Taking thiamine by mouth helps correct metabolic disorders associated with genetic diseases, including Leigh's disease, maple syrup urine disease, and others.Taking thiamine by mouth helps prevent and treat thiamine deficiency. Brain disorder due to thiamine deficiency (Wernicke-Korsakoff syndrome). Thiamine helps decrease the risk and symptoms of a specific brain disorder called Wernicke-Korsakoff syndrome (WKS). This brain disorder is related to low levels of thiamine (thiamine deficiency) and is often seen in alcoholics. Between 30% and 80% of alcoholics are believed to have thiamine deficiency. Giving thiamine shots seems to help decrease the risk of developing WKS and decrease symptoms of WKS during alcohol withdrawal.High thiamine intake as part of the diet is associated with a reduced risk of developing cataracts. Kidney disease in people with diabetes. Early research shows that taking high-dose thiamine (100 mg three times daily) for 3 months decreases the amount of albumin in the urine in people with type 2 diabetes.

More evidence is needed to rate thiamine for these uses.LIKELY SAFELIKELY SAFESpecial precautions & warnings: Pregnancy and breast-feedingLIKELY SAFEIt is not known if this product interacts with any medicines.

ArecaAreca (betel) nuts change thiamine chemically so it doesn't work as well. Regular, long-term chewing of betel nuts may contribute to thiamine deficiency.HorsetailHorsetail (Equisetum) contains a chemical that can destroy thiamine in the stomach, possibly leading to thiamine deficiency. The Canadian government requires that equisetum-containing products be certified free of this chemical. Stay on the safe side, and don't use horsetail if you are at risk for thiamine deficiency.Coffee and teaChemicals in coffee and tea called tannins can react with thiamine, converting it to a form that is difficult for the body to take in. This could lead to thiamine deficiency. Interestingly, thiamine deficiency has been found in a group of people in rural Thailand who drink large amounts of tea (>1 liter per day) or chew fermented tea leaves long-term. However, this effect hasn't been found in Western populations, despite regular tea use. Researchers think the interaction between coffee and tea and thiamine may not be important unless the diet is low in thiamine or vitamin C. Vitamin C seems to prevent the interaction between thiamine and the tannins in coffee and tea.
SeafoodRaw freshwater fish and shellfish contain chemicals that destroy thiamine. Eating a lot of raw fish or shellfish can contribute to thiamine deficiency. However, cooked fish and seafood are OK. They don't have any effect on thiamine, since cooking destroys the chemicals that harm thiamine.The following doses have been studied in scientific research: For adults with somewhat low levels of thiamine in their body (mild thiamine deficiency): the usual dose of thiamine is 5-30 mg daily in either a single dose or divided doses for one month. The typical dose for severe deficiency can be up to 300 mg per day. For reducing the risk of getting cataracts: a daily dietary intake of approximately 10 mg of thiamine. As a dietary supplement in adults, 1-2 mg of thiamine per day is commonly used. The daily recommended dietary allowances (RDAs) of thiamine are: Infants 0-6 months, 0.2 mg; infants 7-12 months, 0.3 mg; children 1-3 years, 0.5 mg; children 4-8 years, 0.6 mg; boys 9-13 years, 0.9 mg;
