I know that this is a board for Glutathione and Cystic Fibrosis, so forgive me if this is off-topic (I do not have Cystic Fibrosis, but other breathing problems). The 2 supplements I have read so much about for helping breathing problems are Glutathione and MSM. I have tried MSM and noticed an immediate difference in my breathing, but unfortunately I got pain in my back/shoulders/neck from it and felt very cold (maybe I was taking too high of a dose?? or going through a detox??) I definitely noticed a positive effect breathing-wise on it, though, and was wondering if anyone else here or anyone here had tried it or if anyone's children here have tried it?
