Yes, I felt happy with Juice Plus, though unfortunately I only took them for about 2-3 months before nausea set in.
I didn't notice so much when I took them, as when I stopped taking them b/c I ran out (my first month's bottles were a gift from a friend). Then all the sudden I felt much less well than when I'd been taking them.
They are expensive, though. There is a sort of a contract in that they send them every so many months (I think it's a four-month supply every four months), but I think they charge you one month at a time and you can always call your rep and say "I've got too many, skip my shipment for the next two months" and then you won't get them. Which reminds me, I need to do that, since not much Juice Plus is going down this gullet for a while longer....
Oh, and did I mention the kiddie gummy ones? - my dd loves them, and she has never been too keen on vitamins, even other gummy, bear-shaped ones. She asks hopefully, "Can I take my vitamins after dinner?" Whoohoo! But unfortunately lately I never remember to give them to her.
