I've been adding 1 tsp of Spirulina to my smoothies these days. It is full of protein, iron, vitamins, antioxidants, and important fatty acids. You can learn more about the health properties here.
In this smoothie I used a banana, frozen mixed berries, spirulina, non diary milk, and a little lemon juice.
It's super tasty and is even husband approved in the taste test. Trust me, he has no problem telling me that some of my creations just aren't gonna work....This one passed the test!
The berries hide the spirulina, but it's in there I promise!
