I just kind of bought this on a whim, so I'm not even sure what all effect it was suppose to have. I figured I probably didn't eat quite enough veggies, and for my entire I've regularly digestive issue after dinner (2-3 times a week). It was more expensive than I wanted it to be, but I figured the per serving cost was worth it for knowing what I was getting and having something backed by at least some data.Well, they can charge me whatever they want now. I'll never stop buying this. I haven't had ANY digestion issues in WEEKS. None. I can't fathom what this stuff is doing to/for me to fix a problem I've had, and been to the doctor for multiple times, my entire life. One of the single most effective products I think I've ever purchased in my almost 40 years.It tastes pretty bad and smells even worse, but it mixes really easy, so I just do the 8 ounces and take it like a shot straight out of the shaker.Hard for me to comment on energy level, because that has never really been an issue for me, but I generally think I feel a little better during the day. I'm also sleeping better, which could mean I'm using more energy during the day.I couldn't be happier. Truly a marvel.
