If you’re a fan of wheatgrass or you’re keen on drinking smoothies and green shakes in general, then you already know how this works. You can juice fruits, green vegetables, and then add powdered spirulina into the mix. It’s a great morning power smoothie or a relaxing beverage after a very tiring day. And the best part of it is that it’s so easy to prepare, you actually can do it within a matter of minutes.
