Squeeze 2 large lemons (1/2 cup lemon juice), into 8 cups of water. You can use a regular hand twist juicer or buy already squeezed lemon juice. Serve with ice cubes and a hint of mint for flavor. Drink throughout the day. You can add sugar or a sugar substitute if desired but try to limit your sugar to reduce your risk of stones. For more information on kidney stones see our fact sheet.
