Stay skeptical about fruit-containing supplements and pre-packaged juices:
A study was done on 27 supplements of pomegranate. Of the 27 tested only 5 appeared to be what the labels actually said.
Another study looked at 45 commercial pomegranate juice samples from 23 different manufacturers in the United States. They each said 100% pomegranate juice on the label, but most of them lied. Only 6 out of 23 were what they said they were.
