Been taking 2,000 mg of MSM (pill format) for several months now. I take it in the evening because when I started it caused unpleasant gas. (That side effect eventually wore off but took time.) What I've really noticed is that my migraines have disappeared! I used to get at least 5 - 10 days a month of headaches which would progress to migraines and optical migraines. Since taking MSM I now experience 1 day of headache a month on the first day my cycle starts. There might be other benefits of taking MSM as time goes on but was really surprised that after years of living off pain relievers, I don't need them anymore.
