Per your article on MSM, asking to hear from people using it.. here I am! I thought to take it for flexibility. I'm in my 40's and I do circus classes for fitness, and I'm strong but more stiff than in my youth. Well, yesterday I took Jarrow Formulas powder (1/2 tsp) with a meal and felt fine. Today I took the same, but about an hour after my meal... and my gut aches! I feel like I've got acid happening... Now I see many websites say "intestinal discomfort" is a common side effect, but NONE of them suggest what I can do while experiencing it. I hope to never, ever have this sensation again (if I try it I'll do it with meals and take even less) but if it happens again, and for all the other sufferers, what the heck can we do???
