Why does oxalate matter?
Oxalate is a substance made by your body. It is also found in some foods. Oxalate leaves the body in urine (pee). When there is too much oxalate in the urine, it can raise the risk of kidney stones. If your 24-hour urine test showed high oxalate levels, eating less oxalate may help lower your risk of getting stones.
How much oxalate should I aim for?
Most people who form oxalate kidney stones should aim for about 40 to 50 milligrams (mg) of oxalate per day. Some people may need a lower amount if their health care provider recommends it.
