As of March 2009, there are no controlled studies backing up any of these claims. According to ABC News correspondent Susan Donaldson, these products have not been evaluated (in the United States) by the FDA, and their efficacy is questionable
There have been a number of disputes regarding the legality of some sites that have been using the free publicity created by Oprah’s show[19] and other celebrities to sell online açaí-based products (mostly juice, pulp, powder or capsules). Marketers of these products make claims that açaí provides increased energy levels, improved sexual performance, improved digestion, detoxification, high fiber content, high antioxidant content, improved skin appearance, improved heart health, improved sleep, and reduction of cholesterol levels. More dubious claims include reversal of diabetes and other chronic illnesses, as well as expanding size of the penis and increasing men’s sexual virility and sexual attractiveness to women
Some of these companies, according to the Better Business Bureau, have lured consumers into accepting ‘free’ samples of açaí berry supplements for weight loss and then used their credit card information for unauthorized charge backs. The BBB warns consumers of these type of practice and advises them to carefully read the "Terms of Service" pages[20] of these sites. In most of the times, the strategy of these companies is to offer customers free trials. People that sign up are asked to pay the shipment fee.The companies register subscribers with their credit card details and after a few weeks, start charging them for other products that will be sent on a regular basis. In many cases, the only way to cancel these programs is by phone. Using this glitch, these companies usually do not respond to the number printed on their site, thus letting the program flow indefinitely.[21] People have been reporting unauthorized charge backs to their credit cards and in most of the cases credit cards or even bank accounts had to be closed in order to put an end to this situation

Cons: the berry rots after only 12 hours of being picked, so unless you are hiking in the amazon, you won’t get them fresh (probably in a juice/supplement form). And of course, the producers of the juice will probably add sugars and other stuff which will take away some of the benefits of this wonderful berry… sometimes there is little of the actual berry in the product and the producer will fill it up with other stuff to save money.

Anyways, there are way more pros than cons. As with everything, moderation is key. The site at the bottom is acai berry that i personally use and really help my life. Find the best acai berry that you looking for, there’s a lot of different acai berry product and some don’t work, make sure to read the ingredients and enjoy.
