Thanks for this lead. I followed the trail on the STTM site to one of the very last posts re: time released magnesium. I now have some on order. I hope it does the trick, as my husband cannot take any other kinds orally.
I have orotate and glycinate and seem to do fine on them up to a certain point bowel-wise, but still have health issues, so probably not getting enough magnesium. The citrate form does a number on me in very small doses. Thanks again.
