I'm kind of torn on this one. I purchased this at a local health food store while looking for something to boost energy. This product delivered. I felt very energized and was able to get through most activities with energy to spare. The reason it gets three stars is the taste. It had a weird chalky taste. It was good, I like the way it made me feel but I would not buy again. Because I use it everyday (add to breakfast smoothie) I am looking for something that taste better.
