I've been taking 300-400mg of magnesium and 50mg/2mg zinc copper. Both are in liquid form trace mineral research. Both of these supplements have been great for me. I came from a diet extremely high in phytic acid and I was undoubtedly deficient in many minerals. Magnesium has helped dramatically improve anxiety and I don't suffer panic attacks anymore. Of course there are other factors that might have helped, but magnesium has given me immediate relief in times of high stress. My previous diet was also so high in copper (Soy, nuts, grain, cacao, vegetable matter in general) that my mental/adrenal state became out of whack. I previously took much more zinc in order to help eliminate the copper and the symptoms. Now I take this balanced dose to ease into balance. I also put a little sea salt in my drinking water for trace minerals and to keep myself from becoming dehydrated.
