Magnesium & Calcium Balance
Health Professional Radio – Interview with Dr. Carolyn Dean, MD., ND.

When you look at magnesium as relates to muscle function, you have to think of calcium as well. They work together. The calcium contracts muscles and then the magnesium relaxes muscles. And it’s more intricate than that. At the cellular level, the magnesium actually opens up the mineral ion channels, allowing a certain amount of calcium to get into the cell, cause a contraction, and then the magnesium actually pushes the calcium out again.

If you don’t have enough magnesium to control that activity, calcium actually will build up in a muscle cell and cause sustained contraction, which ends up being a muscle spasm, which, as you say, is like angina or a heart attack. The largest muscle in the body is the heart, and the area in the body that has the largest amount of magnesium is the left ventricle…http://www.nutritionalmagnesium.org/magnesium-and-calcium-balance/
