Enough magnesium in diet will solve constipation. There isn't enough in a common diet, or maybe paleo, but pumpkin seeds are supposed to be a good source. Some springwater has enough magnesium, but this is apparently rare. I add magnesium bicarbonate to the local springwater, no _great_ effect, but I don't worry about constipation. Note that Phillips Milk of Magnesia is used for this by those who believe in chemical solutions. Maybe you are magnesium deficient? Most people are. William >
