Whether you enjoy a smoothie for breakfast or blend one up for a high-protein post-workout snack, here's a simple (and tasty) way to add more essential electrolytes  to your glass. Instead of adding plain ice cubes to the blender, throw in frozen cubes made of coconut water. It's a great way to add potassium to your diet, which will help you rehydrate even more effectively.
Depending on the size of your ice cube tray, each coconut-water cube is equivalent to about two-thirds to one ounce. For reference, one ounce of coconut water contains five calories , 3.6 mg of calcium, and 60 mg of potassium. For a fruity flare, you can also freeze flavored coconut water. Keep the cubes in the tray, or pop them out to store in a freezer bag or mason jar. Throw four to six cubes in your blender, and you'll love sipping down a smoothie with a tropical twist.
