My vote is for Mag glycinate also. My holistic doctor said this is the best form.
I vote too for magnesium glycinate.... mag oxide just gave me diarrhea.
My cardiologist recommended slow-mag... but like the first mentioned better with some good calcium.
Kal Magnesium Glycinate gets my vote, I tried all the others. This one worked the best for me. Research on supplementing mag, as it requires some calcium too.
I take what my cardiologist recommended It is called Mag-Tab SR they are 84mg tablets and I take 2 tabs twice a day. They are magnesium L-lactate diHydrate They like all magnesium over the counter and I pay $15.09 for 60 tabs. Some insurance companies will cover the cost if the Dr actually prescribes them in writing.
