I make this tasty Cherry Lime Smoothie with various additions, sweeteners were not necessary. Add a bit of creaminess by using a cherry flavored dairy or non-dairy yogurt. You will be adding extra calories and sugar so just be aware, if calories are being counted. The addition of granola takes it to another level in the treat scale. I use R.W. Knudsen brand cherry juice. It's easy to find in the organic section of any grocery store. Check the produce section of your grocer too. You can easily substitute pomegranate juice.
