Good point!
It looks like the main ingredient of the Beano is alpha-galactosidase enzyme.
There’s a cheaper alpha-galactosidase enzyme supplement on Amazon called Enzymedica Bean Assist (Vegan & Kosher, 30 Capsules) which also looks like it’s got less other rubbish in too.
Any one going to try it? I don’t have any Huel left and am reluctant to buy any more on the off chance.
