Calcium

For Patients

If you suspect you have stones, visit your primary care provider or urologist.

If you've been diagnosed with stones and would like to be seen in the Metabolic Stone Clinic, please call (608) 263-4757.

It is best to obtain nutrients from foods, as the body is well adapted to regulating absorption, storage, and metabolism of nutrients in this way.
 
Some studies have associated calcium supplements - not calcium from foods - with an increased risk for kidney stones. If you have had stones and have been advised to boost your calcium intake via supplements, calcium citrate is recommended as it may increase your urinary citrate (a stone inhibitor) as well as calcium.
 
It is important that you supplement only with the difference needed to reach the Recommended Dietary Allowance based on your food intake of calcium.
 
A Registered Dietitian can help you assess your food intake of calcium and the amount of calcium with which you should supplement, if necessary. It is important that you distribute your calcium supplements throughout the day and eat them at meal times, to maximize the GI binding of oxalate as discussed above.
