Learn why calcium levels are vital for preventing cramps and spasms

While there is no single definitive cause of muscle cramps and spasms, I would estimate that a calcium deficiency is to blame 90 percent of the time. The remaining 10 percent can stem from a circulation problem or the body’s inability to use calcium.

Calcium is needed by every muscle fiber. Once a muscle fiber contracts or shortens, it must have calcium to relax. Any muscle in the body may react to improper calcium levels. That's why I say calcium is the vital link in muscle relaxation.
