Magnesium graphic

Magnesium plays an important role in managing kidney stone risks because it helps to reduce the amount of oxalate excreted in the urine. It may also help prevent oxalate from binding with calcium in the urine, a process that can lead to the formation of calcium oxalate or calcium phosphate stones.

According to the Dietary Reference Intakes (DRIs), adult women should consume 320 to 360 mg/day of magnesium. Adult men should consume 400 to 420 mg/day.
