For children following a high-fat ketogenic diet to control epileptic seizures, taking a daily supplement of potassium citrate may help prevent kidney stones, according to a recent study.
Designed to reduce seizure-causing short circuits in the brain, the ketogenic diet includes a high amount of fat-rich foods and very few carbohydrates. Since the diet causes a buildup of calcium in the urine, it's known to trigger the formation of kidney stones in about six percent of users.
In their study of 301 children on the ketogenic diet, researchers found that those who took potassium citrate twice daily were seven times less likely to develop kidney stones. The study's authors suggest that the mineral may stop kidney stones from forming.
