Calcium (as Dicalcium Phosphate and Whey Protein)

The most important and most plentiful mineral in our body is calcium. It is estimated that this major mineral comprises nearly two percent of the entire body weight of an average adult. This percentage may be better noted by the average weight of calcium in pounds in both men and women. Studies suggest that adult males conserve nearly two to three pounds of calcium in their bodies, while females maintain an average of one to two pounds. [1]

The majority of calcium, virtually 99%, is stored in our skeletal structure and teeth. The remaining percent is stored in soft tissues, cell membranes, and bodily fluids. Many individuals supplementing calcium in their diets think of this mineral as being inert, or not having the ability to move or act in bodily processes. We consume this mineral and often times assume that calcium in just stored as a density and protection mechanism for various conditions that are related to both tooth and bone structure. This, however, is untrue. Calcium is constantly flowing into and out of bone.

When certain percentages of calcium are low, bones release stored calcium to optimize blood serum levels. The same is true for the opposite. If blood levels are too rich in calcium, bones will absorb this excess, and the remaining amounts are either absorbed in the intestinal tract or excreted via urine.

There are certain nutrients that directly coincide with our ability to absorb calcium from dietary sources. In the complexity of calcium absorption, vitamin D, parathyroid hormone, and, the amino acid lysine, provide a synergistic effect on overall calcium absorption and its associated metabolic processes within the body. Also of importance are nutrients consumed in the diet that hinder calcium absorption. Nutrients and compounds such as phosphorus, iron, oxalic acid, phytic acid, and fiber, all adversely effect the absorption of this vital mineral.

There are various forms of calcium consumed in the various dietary foods and nutritional supplements we consume to achieve our daily adequate intakes. The average adult readily absorbs approximately 30-40% of all ingested dietary calcium. Listed below are the most common forms of calcium, listed in order of their bioavailability:

  • Calcium aspartate
  • Calcium citrate
  • Calcium carbonate
  • Calcium gluconate
  • Calcium lactate
  • Calcium chloride

Calcium aspartate remains one of the most soluble forms of supplemental calcium. Often categorized as an amino acid, it is actually a calcium salt, formed from the binding of calcium and the amino acid aspartic acid. Aspartic acid is critical in the many delivery mechanisms of calcium to various sites within the body. The combination of a mineral and amino acid provide for far greater absorption, assimilation, and usage. Calcium aspartate has been utilized for muscle cramps, spasms, pain, insomnia, anxiety, and muscular tension. Calcium citrate and aspartate may also be beneficial for individuals concerned with the acid-based balance of their bodies.

Calcium is required for the important processes of growth, maintenance, reproduction (protein structuring of DNA and RNA), tooth and bone growth, the metabolism of lipids, and also helps to maintain the integrity of cell membranes and their permeability at any given time. It may also assist persons in the maintenance of a regular heartbeat, and be equally beneficial for proper nerve transmission and functioning. Calcium is also crucial in the development of many enzymes (e.g. lipase) which allow our body to digest nutrients needed for the maintenance of our overall health.
