We've combined four of our favorite fruits for this smoothie - and it's a yummy one! The flavors are bright and sweet, and it's full of fruity goodness. As far as nutrition goes, this smoothie offers up a bundle of antioxidants from vitamin C-rich oranges and strawberries, to potassium-loaded bananas, and anthrocyanin-packed blueberries. And don't forget all the vitamin K and iron in the spinach.
