Cognitive boost full meal smoothie

As with all smoothies on this site, it's best to rotate recipes.  I would recommend not making and drinking this smoothie more than every other day.
Anytime I hear an advertisement and a product will create significant cognitive boost in minutes or even days, it raises red flags for me and I am concerned about possible side-effects.  While this may help many, as it does me, I would expect to realize benefits over two or three weeks of drinking this smoothie every other day.  You can use the special search engines to the right to search for both health benefits and cognitive benefits of individual ingredients.
Wash vegetables well.  Cut off the very ends of the celery and carrots and discard.  You may also want to cut them into smaller pieces for easier blending.  Peel and discard the peel from the bananas, of course.

My favorite berry is marionberry.  Recently my wife saw a small container of dried mulberry and mistaking it for marionberry, bought it for me.  I used it in this smoothie in lieu of the dried cranberries.  It was quite good and when I looked it up, there were surprising health benefits of mulberry.  I used about 3/4 cups.  It was darker and grittier and definitely gave it a different taste, but it was good.
