Too much calcium can encourage kidney stones and gallstones. The source of both calcium and phosphorus are the foods we eat. Once in the blood, the calcium can go straight to the bones and be deposited there for storage. Bone resorption takes place as needed, liberating calcium for necessary functions in the blood, muscles, nerves, heart muscle, and elsewhere. Excess calcium that does not go back into the bones gets excreted by the kidneys.
Some calcium also remains unabsorbed in the undigested parts of the food and gets excreted.
Movement, walking, and the influence of gravity all help the deposition of calcium in the bones. Lack of use prevents the deposition of calcium salts, so that the process of mineral resorption slowly uses up the available bone mass. To find out more, click here . TO FIND OUT MORE, click here .
