I tried something once that seems like what you are talking about. I was sold in what looked like a wine bottle, and supposedly one shot glass size drink per day was all a person would need to be cured of all their ills. It was essentially concentrated vegetable/fruit/berry liquid, if that makes sense.
I tried a couple of shots, and while they weren't horrible, they were far from tasty. My aunt was selling it, so she was definitely not a good source of "true" info about it. She gave some to my parents, and they used it for a couple of months, and aside from them both getting the ****s for a few weeks, it did nothing for them, and they have many ailments that were curable with the stuff.
If you want to try Vivix(?), go for it. What is worst that'll happen to you, aside from losing a few bucks?
