Leg cramps are a classic sign of too much calcium and not enough magnesium. Calcium enters cells to contract muscles and magnesium is required to escort calcium out of the cells. It takes two magnesium to escort one calcium out of a cell so magnesium can be easily depleted by the presence of too much calcium. Your body will only absorb as much magnesium as it needs, excreting any excess in stool, so it is pretty obvious when you take too much magnesium. If your stool isn’t runny, you aren’t taking too
much! It is much easier to take too much calcium which gives you leg cramps and foot cramps, and in my case heart arrhythmia.
