As far as I understand sanctuary, any juice or mixture of juices is ok that does not contain vitamin c.
i think orange juice is not recommended because of the high levels of vitamin c
however, i don't know if you was juicing something yourself how you would know if it had vitamin c naturally or not, and if vitamin c is not ok with Miracle-Mineral-Supplement because it is an anti-oxidant, shouldn't we also be looking out for the other anti-oxidants that could be in juices as well.
