Juice to use with Protocol 1000+

I've started into my 2nd week on this Protocol 1000+ only to find out that the juices I've been using all have Citric or Ascorbic Acid in them, I just saw a video on YouTube that says not to use anything containing them! Guess I've wasted many hours on some non-useful stuff
So, besides water... what is OK to use in place of it? Please give some samples
Thanks,

Sorry; I should have checked but Mr. Humble has written info about the taste and juices etc. , he wrote "TASTE MANAGEMENT". Thanks.
