Are you prone to kidney stones, or someone you know?

Many people believe that kidney stones are caused by an excess of calcium, but in fact it is a lack of magnesium that is the culprit. Magnesium prevents the formation of these stones by inhibiting the binding of calcium with oxalate, the two compounds which make up these stones. Kidney stones can be excruciatingly painful, so it is good to know that something as simple as magnesium supplementation can prevent them!
