Supplements for Kidney Stones

Answer:

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 foods 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 advised to avoid high-dose calcium supplements and to stay well-hydrated (as inadequate fluid intake can increase the risk of kidney stones). 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.

Interestingly, too little citrate in the urine (hypocitraturia) is also a risk factor for developing calcium oxalate kidney stones.
