Hi, Just want to post something that is working for me. I tend to have colon spasms and for me, I know that the colon spasms mean that the food is "stuck". This may not be for everyone, but for me that is what it means. And it doesn't even mean really that I'm constipated, because my body is able to have bowel movements, but the stool itself is very dry and my colon thinks it's stuck so it starts spasming. I have one spot in the left side where it was almost spasming after everything I ate, and I was on a very restricted diet. So, due to another health issue I was having, someone told me to try magnesium to stop a different health issue. I began to notice that I wasn't having any colon spasms, and that I could stop taking my black strap molasses and black cherry juice morning and evening to keep bowels moving. The magnesium is keeping the stools moist. I am able to eat now without the god awful colon spasms. It is 175 mg Magnesium Oxide and 100mg of chromium capsules. I take one with breakfast and one with dinner. And it's working. It didn't help my other health problem, but it has sure stopped my colon spasms. Just seems too good to be true. HOpefully there are no long term side-effects with taking this. Thanx for listening, Genie
