 Magnesium is a mineral that's important in every part of the body, kidney, heart, and muscle especially. It is good for your teeth, your muscles, your bones, for your entire body. Magnesium is essential. Usually you can find it in green leafy vegetables, grains, nuts, muscle spasm, weakness, restless leg, nausea, vomiting, or arrhythmias, or there are quite a few different forms of magnesium. We have magnesium citrate, aspartate, sulfate, glycinate, they're all different salts. They all absorb very, very well. The one that doesn't absorb very, very well is magnesium oxide. Magnesium oxide is milk of magnesium, so it acts as a great, great laxative or antacid. I would surely recommend using magnesium glycinate. The reason being is it probably will not cause diarrhea, in fact it doesn't cause diarrhea, and you get great absorption. Magnesium citrate is fine, except it can cause diarrhea. Magnesium citrate, as you well know, is citrate and magnesia, and we all know what citrate and magnesia does. It causes diarrhea. Anyway between 250 to about 750 milligrams a day, really depending on what you're using it for. I'd like to see you take a vitamin B6, vitamin B6 that helps with the absorption of magnesium. I would also like you to take things like vitamin B5. The reason being is it's good for stress. It helps to normalize the adrenals.
