hi jk98 : how strong do you feel your system is? the reason I ask is if you do not feel stable ,then be very careful with msm ,I know for a fact that it does mobilize mercury ,I used it for about 3 weeks back in oct-nov and whent down hill very quickly and was only using half a capsule every other day , it is an organic sulfer compound , if you have a problem with sulfer foods then msm will give you the same problems
