NOW Foods Vitamin B-1 (Thiamine) 100mg (100 Tablets)
by NOW Foods
"100mg thiamine per tablet — the essential B1 for energy metabolism and nerve function with 100 tablets under $10"
Overview
NOW Vitamin B-1 provides 100mg of thiamine (vitamin B1) per tablet. Thiamine is essential for carbohydrate metabolism — it's a cofactor for pyruvate dehydrogenase (which converts pyruvate to acetyl-CoA for the Krebs cycle) and alpha-ketoglutarate dehydrogenase. Without adequate thiamine, carbohydrates cannot be efficiently converted to ATP. Thiamine is also critical for nerve function — deficiency causes beriberi (peripheral neuropathy) and Wernicke-Korsakoff syndrome (brain damage). Groups at risk for deficiency include heavy alcohol users, those with malabsorption, bariatric surgery patients, and those on loop diuretics. The 100-tablet count provides over 3 months of daily supplementation.
