Many people think that the essence of stones is calcium and that calcium supplements will cause stones. This is a very big misconception.
Urinary stones are a combination of various factors, mainly abnormalities in the body’s metabolism that lead to excess urinary calcium, oxalic acid, uric acid, or cystine, precipitating crystals that collect and grow, eventually forming stones.
Appropriate calcium supplementation does not lead to an increased incidence of stones. It is supplementation with extra-large doses of calcium, such as more than 2500 mg per day, that can cause hypercalciuria and urinary stones.
Rational calcium supplementation not only does not increase the risk of stones, but it also binds to excess oxalate in food and is excreted through the intestine in the stool, effectively reducing the amount of oxalate excreted through the urine and reducing the incidence of urinary stones.
Therefore, regular monitoring of blood and urine calcium indicators will provide peace of mind for calcium supplementation.
