I absolutely love that kombucha! I want to try the green drink, and just the original. I really could gulp the whole thing down. I've asked that question here on the forum. I think it's questionable since it's made with SUGAR!!! the actuall sugar content of a whole jar is 2. So when I've drank it, I just take sips, never drinking much at a time for that reason.
I've never tried the cocunut kefir, but I really want to since I can't tolerate regualr kifir. It also has a sugar content of 3, (1 cup) with some ingredients saying dextrose, and pectin. forms of sugar, so i'd probably just take sips of that too.
Just as with the kombucha, if the kefir is fermented long enough all the sugar is destroyed.
