I have only had one month's experience with this product, but it has been very positive. There were a few days here and there when I didn't take it because I was out of town. Overall, I thought the product was very viable. It has a sweet, but not too sweet taste which is enhanced by the deep berry flavor.
I did experience a noticeable increase in energy, which was most noticeable later in the afternoon and early evening when I generally have an energy crash. It appears to contain just about every red or blue fruit and vegetable on the planet, in a highly extracted form. Since I did not experience any spikes in energy or feelings of "speediness', I feel confident that there is no caffeine or guarana in the product.
The only downside to the product is that it is expensive. I did note, however, that there are price breaks if a buyer can afford to buy at least three at a time.
Bottom Line: Yes, I would recommend this to a friend
