Is juice plus any good for you?

I’m concerned for a friend. She’s tried dieting for years and nothing ever works for her so she’s just purchased this juice plus and you have to shakes as a day aswell a healthy meal. I’ve researched abit online and she just listened to what other people told her about the Product instead of looking at reviews before buying! Online there is good and bad things about it. Few people are saying its a scam and nobody knows what is in it? Just wondering if anybody could tell me anything they know about it? What’s it in, if its good for you etc. Thanks.
