Vitamin B1 (Thiamin)
Overview
Vitamin B1 (thiamin) is a water-soluble vitamin critical for energy metabolism and cell function, particularly in processing glucose and amino acids. Adults need 1.1–1.2 mg daily. No upper limit has been established. Deficiency is common among people with chronic alcohol dependence and can cause Wernicke-Korsakoff syndrome — a severe neurological condition causing permanent brain damage. Other at-risk groups include older adults, people with diabetes, HIV/AIDS, or after bariatric surgery.
