Vitamin B1 Thiamine
Vitamin B1, also known as thiamine, is an essential water-soluble nutrient crucial for energy metabolism and proper nervous system function. This vital vitamin plays a key role in converting carbohydrates into energy, supporting brain health, and maintaining a healthy nervous system. Thiamine acts as a coenzyme in various metabolic processes, including the breakdown of sugars and amino acids. Research has shown that adequate thiamine intake is particularly important for preventing conditions such as beriberi and Wernicke-Korsakoff syndrome, especially in individuals with alcohol use disorder or malnutrition.
