This smoothie calls for 2 tablespoons of hemp hearts which provide a huge nutritional boost to this smoothie, including more than 6 grams of complete protein, as well as omega-3 fatty acids, magnesium, and more. Hemp hearts, kale, and dates require a strong blender to blend them smooth (a Vitamix blends them into a super creamy shake). If your blender can't blend the hemp hearts, kale, or dates smooth, I recommend swapping out the hemp for a serving of your favourite protein powder and swapping the dates for pure maple syrup (otherwise, you'll just have a grainy end result). You can also swap the kale for baby spinach as it blends easier.
