Yes, magnesium oxide is really just a laxative. Citrate is excellent but I j\use the glycinate. Capsules only so they get in there.
I use both depending on what’s on sale I like capsules better, easier to swallow. I’ve managed to reverse the -4 OP to a -3.5 in all but 2 areas just using Vitamins and Minerals. Sure beats that ER trip for A-Fib Fosamax caused. Won’t know if it’s less until they do the next Bone Density test. Gastro has me on Pharma grade Potassium once to twice a day depending on the Gastropresis that makes it a necessity.
