Calcium supplements can be bought in the form of a tablet. Calcium supplements are found in different forms. The supplement that has the largest amounts of elemental calcium will allow you to take fewer tablets per day to meet your calcium needs. It comes in different doses and size of tablets. Some supplements are now fruit flavored and chewable.
Some antacids have a lot of calcium carbonate.
Make sure they do not contain any aluminum. Aluminum keeps the body from using calcium effectively. If an antacid is used to increase calcium in the diet, there must be enough Vitamin D elsewhere in the diet for the body to use the calcium. Sometimes calcium carbonate may cause a person to have gas or become constipated. Calcium Citrate is used well in the body and may reduce the chance of having gas or becoming constipated.
