As opposed to the usual six juices, iZO actually calls for double that, however some of the 12 incorporate various teas brewed from foreign ingredients (reishi mushrooms?).
Pedants used to insist that words like mechanise and organise be spelt -ize, since they come from Greek roots and -izo is a common Greek way of forming verbs.
Before I embarked on iZO, I dutifully read through the website and was intrigued to see that this cleanse format was quite different than any I had tried in the past.
