How Does Calcium get absorbed by the Body?

As calcium is ingested, the acid in the stomach begins to break down the molecule into its atomic components. At this point the calcium is in its ionic, or positively charged, state. In this state, the calcium can pass through the intestinal tract, into the bloodstream, and into the bones. It is this rate of calcium absorption, or bioavailability, that determines how much of the ingested calcium actually can be used by the body. The higher the bioavailability, the more calcium ions can travel into the body. In addition, the faster the supplement can obtain this ionic state, the faster it becomes available for absorption. Since time is critical, it is important to ensure as much calcium is absorbed before it passes through the body. The bioavailability or absorption and uptake of calcium are partly a function of pH. Acidity favors absorption while alkalinity hinders absorption. This is important to understand since many calcium users also take antacids, acid reducing or acid blocking medications. With the long term us of acid reducing/blocking medications; these medications prevent the break down and absorption of calcium
