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. The dose range is defined in GalU (300–1,200 per meal) — a bare mg figure is not converted and is left unscored rather than guessed.
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
300–1200
galu
GalU per meal: OTC products deliver 300 GalU per tablet (Beano-type) with 1–3 tablets per gas-forming meal; RCTs used 300–1,200 GalU. A mg figure without GalU on the label cannot be scored.
Clinical evidence
Limited clinical evidence. Small RCTs support reduced flatulence; potency measured in GalU activity units
