Though most people realize the importance of calcium supplementation, few are aware that not all calcium supplements are created equal. In fact - calcium carbonate - which is the same form of calcium found in many other calcium supplements on the market today - has a low rate of absorption and poor tissue retention. This means that, even though an individual may take high doses of this form of calcium, very little is actually absorbed for use by the body. In addition, other forms of calcium, such as calcium carbonate, can cause serious gastrointestinal problems as well as other harmful side effects.

Optimal Calcium contains the only patented form of amino acid chelated calcium, ensuring that calcium is absorbed virtually completely for optimal use by the body.
