Vitamin B1, also known as Thiamine, is an essential water-soluble vitamin that plays a crucial role in cellular metabolism. It is vital for converting nutrients into energy, particularly carbohydrates, which are the body's primary energy source. Thiamine is also involved in nerve, muscle, and heart function. Because it is water-soluble, the body does not store large quantities of Thiamine, requiring regular intake through diet or supplementation.
Dietary sources of Thiamine include whole grains, legumes, some meats (like pork), nuts, and fortified cereals. Deficiency can occur due to inadequate dietary intake, excessive alcohol consumption, certain medical conditions, or medications. Severe thiamine deficiency can lead to conditions such as beriberi, which affects the cardiovascular and nervous systems, and Wernicke-Korsakoff syndrome, often seen in individuals with chronic alcohol use disorder, which impacts the brain (NIH Office of Dietary Supplements).
