Modest Calcium Restriction Guidelines
Your recent 24-hour urine collection revealed high levels of calcium. As the primary constituent of most urinary stones, calcium has long been heralded as one of the main risk factors for stone formation. Therefore, we recommend that you moderate your dietary calcium intake in order to prevent future stone formation. Specifically, you should limit your dietary calcium to 800 to 1200 mg each day.
