<unk>  is defined as urinary magnesium excretion of < 50 mg/day.
Magnesium is known to be an inhibitor of calcium nephrolithiasis by apparently increasing the solubility product of calcium oxalate and calcium phosphate. This condition may coexist with hypocitraturia in approximately 65% of patients, and low urine volume (< 1 L/d) in approximately 40% of patients.
Many patients with nephrolithiasis report a limited intake of magnesium-rich foods such as nuts and chocolate, suggesting the dietary basis for this condition.
