I had purchased the smaller bottle of Acai Juice Extreem and really loved it but wished I found this one first since it is a lot for the money. I have been trying Acai with different colon cleansers but really wanted to use a strong dose for continuous use. So far, I have lost about 4 pounds over when I take it regularly and dont over eat. Its good to buy from a reputable source so you know you are getting pure acai. I have tried 3 different brands but I found this one to work best and plan to stick with it.
