I've been having some difficulty finding a good magnesium supplement too. The malate form can be dangerous for us to take as it supposedly mobilizes alumininum, but I don't think it has a strong bond to the metal so probably just moves things around. The citrate is from fruit which I can't take either. The oxide form is well known to cause diarreha and of course happens to me <img src="/ubbthreads/images/graemlins/crazy.gif" alt="" />. The aspartate form is actually an exitorary amino acid and this worsens my anxiety symptom..........so what I am left with is the magnesium carbonate form.............which I have just started to use, but seems to be going well. The only drawback is this form needs stomach acid to be absorbed, so I take a little HCI supplement with it as I know I am low in acid.
