There is no cheaper and better alternative bioavailable. From MgCitrat I gotten bad diarrhea, MgChlorid I can take very good. My premature beats (I had about 2 Mon) are already almost gone. I sleep better and wake up on their own at that fatigue is gone.
Just wonderful and so cheap! Without fillers, aluminum foil, packaging.
I wear it as a magnesium oil on the skin. It tingles a little, but can easily bear.
A strong buy recommendation!
