Calcium is a major mineral essential for healthy bones and teeth. There are several minerals known to be essential to the human body and which must be obtained from food. The major minerals (calcium, magnesium, phosphorus, sodium, chloride and potassium) are needed in the greatest quantities or are present in large amounts in the body. The three main functions of minerals are as constituents of the skeleton, as soluble salts which help control the composition of the body fluids, and as essential adjuncts to the action of many enzymes and other proteins.

What Causes Kidney Stones? Not Calcium Supplements

The traditional wisdom was that dietary calcium is one of the leading causes of kidney stones, and to prevent kidney stones patients were recommended to dietary calcium. The research has proved this wrong, but. Normal dietary calcium intake, together with reduced salt and protein, is now advised.1

physicians for prescribing a low-calcium diet to prevent kidney stones. This approach makes little sense if you understand how calcium in the body. Calcium levels in the blood are held fairly steady balance by the inclusion of calcium from the diet and calcium from bones, if necessary. Changing the amount of calcium in the diet causes very little change in blood levels of calcium The kidneys filter substances from the blood, so that changing the dietary intake of calcium does not alter the amount of calcium that is filtered by the kidneys . In fact, calcium and protein intake is recommended in the therapy, based on declining kidney stones. Calcium restriction in stone form, is not recommended because they have a negative impact on bone and the incidence of stones.2

The recommended daily intake of calcium for adults is 1000 mg per day, but research shows the average American adult is always 600 mg of calcium daily from their food.3-4 Any nutritionist, doctor or text suggested calcium reduction is in serious mistake. It was even suggested that low calcium May an cause of kidney stones.5

There are also competitors argue that all calcium supplements that are not fully absorbed contributes to kidney stones. The truth is that unabsorbed binds to calcium oxalate from food digested in the gut and reduces the elimination of oxalate in the urine, which is how kidney stones form. To prevent kidney stones, it is recommended that a calcium-rich diet and avoidance of Oxalates. If calcium in the diet with oxalate, then bind calcium and oxalate in the intestine. This way, less calcium and oxalate enter the blood so that Oxalates are not available to bind with calcium in the kidney.
