Vitamin B1

From WikiMD's Wellnesspedia

Vitamin B1, also known as thiamine, is an essential nutrient that all tissues of the body need to function properly. Thiamine was the first B vitamin that scientists discovered. This is why its name carries the number 1. Like the other B vitamins, thiamine is water-soluble and can't be stored in the body; however, the body maintains a small reserve of these vitamins in most cases.

Function[edit | edit source]

Thiamine plays a critical role in energy metabolism and, therefore, in the growth, development, and function of cells. It helps the body cells convert carbohydrates into energy. It is essential for the functioning of the heart, muscles, and nervous system.

Sources[edit | edit source]

Thiamine is found in a wide variety of foods at at least low levels. Some of the best sources of thiamine are lean meats; dried beans, peas, and soybeans; and whole or enriched grains and bread. Milk, fruits, and vegetables are not very high in thiamine, but when consumed in large amounts, they become a significant source.

Deficiency[edit | edit source]

Thiamine deficiency can cause numerous health problems, including heart problems, nerve damage, Wernicke-Korsakoff syndrome (a brain disorder that affects memory), and beriberi, a disease that can cause heart failure.

Recommended Intake[edit | edit source]

The recommended daily intake of thiamine varies depending on age, sex, and life stage. For example, adults need more thiamine than children, and pregnant or breastfeeding women need more thiamine than other women.

Overdose[edit | edit source]

Although not common, consuming excessive amounts of thiamine can lead to an overdose. Symptoms of a thiamine overdose may include weakness, irregular heartbeat, nausea, and difficulty sleeping.
