I don't take it in pill form but I do drink juices with it. I can tell you taht I was loosing weight. I usually make shakes in the morning for breakfast and got in a workout. So was it the workout or the acai in the shake? I am sorry but can't tell you.
I can tell you that I feel better when I drink the juices with the acai.
I was using it, and I lost 9 pounds in the first week. I did nothing different except take the pills. If you are using acai, it is a good idea to use a colon cleanser, too. We hold quite a bit of undigested food in the colon, and cleansing your colon is cleaner and healthier.
