Too Rind or Not to Rind

I have read on some sites that recommend leaving the rind on your citrus for the vitamins. Others state to take it off because of the taste. I left half of the rind on half of a lemon. The predominate flavor of this mornings juice is lemon rind. So, I will be taking off all of it next time.
Today's mix: kale, chard, lemon, apple, spinach, and Romaine. I added some cayenne pepper but not enough to consider it spicy.
