Calcium is a major mineral with many functions in the body. It is a major electrolyte and is also involved in chemical functions as well as the physical makeup of bones, teeth, and connective tissues. Calcium however, is one of the most difficult minerals to absorb. Most sources of calcium are highly alkaline, making them hard to absorb. In order for calcium to be absorbed effectively it must be acidified to a relatively low pH or acid. This may be accomplished in supplemental form through the use of chelation. By binding the calcium to an acid such as malic acid or citric acid, the bio-availability of calcium is greatly enhanced. Some of the many functions of calcium include the building of bones and teeth, reduces insomnia, necessary for maintaining the delicate acid/alkaline balance of the body, aids in regulation of heartbeat, assists in the clotting of blood, and aids muscle contraction and nerve transmission. Deficiency symptoms of calcium would include leg cramps, numbness & tingling of hands and feet, nervousness, heart palpitations, and excessive menstruation in woman.
