| Beclotiamine | An impurity of Thiamine. Thiamine, also known as vitamin B1, is a water-soluble vitamin essential for cellular energy production, nerve function, and overall metabolic health. It plays a crucial role in carbohydrate metabolism by acting as a cofactor for enzymes involved in glycolysis and the Krebs cycle. Thiamine deficiency can lead to serious conditions such as beriberi (wet or dry), Wernicke-Korsakoff syndrome, and congestive heart failure.
