About Alpha-Galactosidase
Enzyme that breaks down indigestible oligosaccharides (raffinose, stachyose) in beans and cruciferous vegetables before they reach gas-producing colonic bacteria. Small RCTs support reduced flatulence. Potency expressed in GalU, not mg.
What Alpha-Galactosidase supports
- Reduces gas from beans and high-FODMAP vegetables
How much Alpha-Galactosidase to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
10–100
mg
Dosed in GalU (galactosidase units), not mg — typical products provide 150-450 GalU per serving (e.g. Beano). mg range is nominal for resolution; activity-unit dosing is not captured by the mg curve.
Clinical evidence
Limited clinical evidence. Small RCTs support reduced flatulence; potency measured in GalU activity units
