- Very low evidence3 studies
Across 3 studies, 1 reported a beneficial small effect of Vitamin B1 (as part of a multi-nutrient supplement) on left ventricular ejection fraction, while 2 studies found no significant effect (neutral). The most-studied dose was 50–100 mg/day in clinical populations with heart conditions or undergoing cardiac surgery. The median study duration was short (15 days), so longer-term effects remain unclear. Evidence is small and preliminary.
Dose: 50–100 mg/day
