This spinach smoothie from trainer Harley Pasternak is a favorite of his celebrity clients (Julianne Hough is a fan!) for helping them stay on the right track.
Spinach is the star in this creamy smoothie, and for good reason — with just one 16-ounce serving, you'll be getting your entire recommended dietary allowance of vitamin A (great for healthy skin, hair, and eyes) and bone-building vitamin K, as well as an impressive amount of essential nutrients like manganese, potassium, and vitamin C. This 300-calorie smoothie is a good source of protein, making this veggie-packed smoothie a smart breakfast choice.
