Supplements for Kidney Stones


Calcium oxalate stones, the most common type of kidney stone, form when calcium and oxalate (or oxalic acid, which is naturally present in many plant-based and is also produced by the body as a waste product) bind together, forming crystals that can accumulate into a hard "stone."

Having excessive calcium in the urine (hypercalciuria) is the most common cause of calcium oxalate kidney stones. People prone to calcium oxalate kidney stones are also often advised to stay well-hydrated (as inadequate fluid intake can increase the risk of kidney stones), and those with high urinary oxalate levels may also be advised to maintain a low-oxalate diet, which typically limits intake to about 50 to 100 mg of oxalate per day.
