This smoothie packs a major green punch! It’s loaded with the healthy taste of summer thanks the addition of berries, spinach, and avocado. The spinach contains loads of vitamin K and A, as well as iron, and the inflammation-fighting avocado… hello, healthy fats and potassium! It also helps give the smoothie its creamy texture. And as an added bonus: ground flax boasts heart-healthy Omega-3 fatty acids and fiber!
