Blackberry-Kale Protein Smoothie

I like to make this refreshing smoothie throughout the summer with the kale and berries growing in my garden. Sometimes I will use strawberries or blueberries in place of the blackberries. The amino acid powder and collagen peptides provide quite a bit of easily absorbable amino acids to keep you fueled for hours. I will often have this smoothie as my lunch, especially if I plan on exercising in the afternoon.
