Right now I'm trying to take vitamin D which normally causes me a lot of problems, one of which I think is magnesium deficiency. But I haven't been able to tolerate oral magnesium and I find the transdermal oil to be very messy, as well as irritating to my skin, so even though I use it daily I have trouble using as much as it seems I need. I found two possible solutions in doing some research last night on what's work for people. One person suggested using a powdered magnesium in water and slowly sipping it throughout the day. Somehow this supposedly prevented GI trouble. Another idea was slow release magnesium, which is pretty pricey. Has anyone tried either of these approaches? Or has anyone found some other way to tolerate oral magnesium? In the past I used a capsule and even when I dumped out almost all the powder in the capsule I had trouble with diarrhea so I don't think lowering my dose and slowly building up will work unless I can first find a dose or method of taking it that my body can tolerate. Thank you.
