They claim to have a specific strain which produces lots of lactase, which is possible. I agree with you on principle though.
Another piece of data we have is all the anecdotal stuff about it simply working for people, personally I think it is pretty hard to placebo not getting diarrhea.
I do agree with you about the supplement industry being full of scumbags. Let me know what you would like from us to help win you over, besides the double blind which is in progress, but imagine if it was not an option, what else?
