Interactions
synergistic. Magnesium is required to convert thiamine into its active coenzyme form (thiamine pyrophosphate, TPP); magnesium deficiency impairs thiamine utilization even with adequate intake
synergistic. B vitamins work as coenzymes in interconnected metabolic pathways; B1, B2, and B3 are all required for energy metabolism in the electron transport chain
inhibits. Chronic alcohol consumption dramatically impairs thiamine absorption via reduced expression of intestinal thiamine transporters (THTR1/THTR2) and increases renal excretion
inhibits. Loop diuretics (furosemide) and thiazide diuretics increase urinary thiamine excretion, potentially causing deficiency in heart failure patients
