​By mass, calcium is the most abundant metal in our body. In fact, ninety nine percent of the calcium in our body can be found in our bones and teeth. Calcium is also the fifth most abundant element by mass in our earths crust, and is essential for most living organisums . ​In cell physiology calcium aids in the vital function of many cellular functions including muscle contraction.

​Calcium has many uses as an industrial metal and can be found in things like fireworks, fertilizer, rocket propellant, various food additives and even for bleaching agents and deodorants.


​The only role calcium has in the human body is for strong bones and teeth, and the typical American diet has an efficient amount of calcium.


​It takes a minimum of 5 cups of calcium rich foods to get the daily recommended servings, and 80% of the American diet does not even get close to consuming that amount. 

​We have all heard that 99% of all calcium can be found in our bones and teeth. But where can we find the additional 1%? ​Our muscles contain the all important 1%, and this 1% is used for muscle extension. In my September blog I wrote about the role that magnesium plays in muscle extension, ​and now you have the rest of the story. Calcium for muscle contraction and magnesium for muscle extension.

Calcium also aids in the relaxation of nervous system which can help to get a good nights sleep. I'm sure you have all heard about drinking a nice warm glass of milk before bedtime.

A potent combination for runners; calcium and magnesium. We want the leg muscle to extend quickly and with force,(CALCIUM) and (MAGNESIUM) for quick muscle contraction so the cycle can repeat itself over and over and over again with as much minimal effort as possible.
