Thiamine, also known as vitamin B1, is an essential nutrient that plays a crucial role in metabolism. It is a water-soluble vitamin, meaning the body does not store it and requires a regular intake through diet. Thiamine is vital for converting carbohydrates into energy, a process that fuels the body's cells. It is also involved in nerve function and the synthesis of DNA and RNA.

A deficiency in thiamine can lead to a serious condition called beriberi, which can manifest in two forms: wet beriberi affecting the cardiovascular system and dry beriberi impacting the nervous system. Symptoms of beriberi can include fatigue, muscle weakness, nerve damage, and in severe cases, heart failure. Wernicke-Korsakoff syndrome is another neurological disorder associated with severe thiamine deficiency, often seen in individuals with chronic alcoholism.

Thiamine is found in a variety of foods, including whole grains, pork, poultry, eggs, legumes, nuts, and seeds. Fortified cereals and breads are also significant sources in many diets. Recommended daily intake varies based on age and life stage, with increased needs during pregnancy, lactation, and for individuals engaging in strenuous physical activity. Absorption of thiamine occurs in the small intestine, and it is transported throughout the body via the bloodstream. While generally considered safe, excessive intake of thiamine through food sources is unlikely to cause harm.
