msm

Been having some joint issues using Winnie and this MSM and glucosamine doesn’t seem to be helping it seems to hurt me worse on days I’m doing High repetitions and really pushing the envelope I’m training five times a week and I’m trying to take days off here and there and get some good rest do...

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
