Even the most carefully chosen diet often lacks sufficient calcium. Calcium is not only one of the most abundant minerals in our bodies, it is also one of the most critically important. It requires constant replenishing from the foods we eat and the supplements we consume. Satisfying our calcium requirements is no easy task. Like the majority of minerals, calcium is not easily absorbed, so the source and quality of the calcium we consume is of great importance. As well, calcium does not work alone, the presence and interaction of other nutrients must also be considered. Age and gender are also important factors as men and women have unique calcium demands and experience very different hormonal challenges as they age.

Our modern lifestyle presents additional hurdles. A number of dietary and environmental factors contribute to the leeching and depletion of calcium from our systems. An effective calcium supplement must address all of these concerns.
