Leafy greens are the best dietary source. Chlorophyll is constructed out of magnesioum magnesium the same way that hemoglobin is constructed out of iron. Usually with magnesium supplementation you know when you need to back off when you get the scoots. It sounds like you have reached that point and then some. It is easy to take too much of that stuff. The dosage is pretty small. You could also look into transdermal magnesium or magnesium oil to get it via the skin. This method is especially useful to people who are just starting out and have absorbtion problems because of a leaky or irritated gut. You can find magnesium oil at a good health food store or online.
