I want to take this mag oxide to relieve constipation brought on by Multiple Sclerosis. Now I take cal/mag citrate for muscle tightness but it does nothing for constipation. Not willing to do Milk of Magnesia. I want to stop the use of Miiralx as prescribed my my md. If taking the mag oxide with acidic food or in my case my body is acidic because of needed MS medications, wouldn't that help absorption?
