While acai is a great natural super food, the Acai Berry 500 reviews are not so great. The manufacturers do make claims that it is the ideal weight loss supplement. However, there is very little research or evidence to support this claim. So don't go by all that you read on the net. You could take Acai extracts for its numerous other benefits. It helps to detoxify and cleanse your system and gives you an energy buzz that lasts throughout the day. But as far as weight loss properties are concerned, don't get too taken in. A diet and exercise schedule will definitely be better.
