They also advise that " If you are taking acid blockers for indigestion, reflux or other gastrointestinal conditions, your body may use calcium citrate better than other calcium compounds.
Acid blockers reduce the acid in your gastrointestinal tract that is usually required for calcium absorption. However, unlike other calcium compounds, calcium citrate does not require an acid environment for calcium absorption.
Finally, they suggest that you "Read the supplement label to find out the calcium content in milligrams (mg) per serving. The label may refer to the calcium as elemental calcium. This distinguishes the weight (mg) of calcium alone from the weight (mg) of the calcium compound (such as calcium carbonate, calcium citrate, calcium phosphate, or others). It is also important for you to check the serving size to find out how many tablets or capsules provide a specific amount of calcium."
