I have been taking a supplement called MSM and had to stop it because it seem to be upsetting my stomach. Nothing I read online says that it can do that and I don't think it's a coincidence so what do you think is going on. Is there a possibility I'm just allergic to this particular thing
MSM as in methylsulfonylmethane ?
It could I guess but that goes with anything.
Are you talking about "methylsulfonylmethane" ?
