Spirulina is a type of blue-green algae that contains a number of nutrients, including B vitamins, beta-carotene, and vitamin E. Spirulina also contains antioxidants, minerals, chlorophyll, and phycocyanobilin and is commonly used as a source of vegan protein. We topped this Superfood Spirulina Protein Smoothie Bowl with our Vanilla Almond Clean Lean Protein Bars by Nuzest for some added crunch!
