Acai Berry Products

Acai is no diet miracle.

  • Contains antioxidants
  • Health claims lack long-term proof
  • Online companies may be scams
  • Online reviews are often bogus

The Internet is saturated with weight-loss ads for acai (pronounced "ah-sigh-ee"), a Brazilian berry that is turned into pills and juices. Sellers promise these supplements will melt fat and detoxify your body, in some cases implying that the products are endorsed by celebrities like Rachael Ray or Oprah Winfrey. Usually, they promise a free trial. There are so many of these products on the market that we're not covering all of them; rather, we're discussing acai berry as an ingredient in what's now hundreds of products.

You can find plenty of reviews for acai berry products, often linked to what appears to be somebody's personal weight-loss blog. However, experts say these purported reviews for acai berry weight-loss products are usually bougs. Furthermore, nutrition and health advocates say the supplements are ineffective, and many people complain of having been bilked by the "free" trials -- sometimes for hundreds of dollars.

Reliable research has shown that the berry does contain antioxidants. However, so do lots of ordinary fruits and experts say there is no proof that acai berries can improve health in any way or contribute to weight loss. Oprah Winfrey and Rachael Ray have both added disclaimers to their websites saying they don't endorse any specific acai berry products, even though they have both had guests on their TV programs discussing the health benefits of acai berries.

Thousands of people who have purchased acai berry weight-loss products have complained about Internet sellers to the Better Business Bureau. Most of them either have had trouble canceling their "free" trial (complaints include calling the toll-free number repeatedly and being automatically disconnected every time, finding the number out of order or being placed on hold for up to 75 minutes) or have been charged despite canceling their orders. Some consumers say they had to cancel credit cards and close bank accounts before the charges stopped, according to the BBB.

If you go looking for online reviews of acai berry products or acai sellers, be wary. Experts say many reviews, blog comments and entire blogs are staged by the companies themselves. The Center for Science in the Public Interest (CSPI) credits a watchdog blog,, for discovering that several weight-loss blogs -- supposedly belonging to ordinary women who lost weight with acai -- show the same fake before-and-after photos. At least 75 blogs show the same easily obtainable stock photo of a German model named Julia who has nothing to do with acai or any of the companies, CSPI says.

If you decide to try acai berry supplements or juices, buy them in a retail store so you're not sucked into a scam. Although there's no scientific evidence that acai berry products will help you lose weight, you might like the taste of the juices just as you would other fruit juices.

Government and nonprofit agencies -- including the Center for Science in the Public Interest, Better Business Bureau and Connecticut attorney general's office -- have investigated allegations of acai-related online sales fraud. Both ABC News and The New York Times have reported on sellers' questionable claims. The blog maintains a list of what the blogger says are fraudulent acai berry websites. says acai berry can have some positive health benefits, but is critical of the many impostor products out there. Both and deny any affiliation with specific acai products, although some doctors on recommend acai berry supplements in general, and Ray's site includes several recipes made with a specific brand of acai liqueur.

The Center for Science in the Public Interest credits this blog -- which CSPI says is "written by an ad-industry insider" -- for first uncovering the fake weight-loss blogs used to tout acai. The blogger lists more than 120 acai review and blog sites that he or she believes to be phony, along with a brief synopsis of each site and a list of the various acai and detoxification products that are advertised. It looks like the list of fake sites is updated roughly every year.

Where to Buy

Zerosmoke consists of a pair of 24-karat gold-plated magnets that attach to your ear, promising to cure you of the desire to smoke. The magnets, which are meant to be worn for two to four hours a day, supposedly trigger acupuncture pressure points on the outer ear to eliminate cigarette cravings by activating neurotransmitters in the brain.

It's hard to find credible, independent evaluations of this product, although the Zerosmoke website contains several glowing reviews. We did find some interesting posts on, where a handful of users give Zerosmoke the lowest possible rating. One user says "the only people this product is going to help are the hopelessly suggestive and the predators that profit from selling to the suggestive."

An unscientific test by TV station KVBC gets mixed results: One couple says they quit smoking for the week they wore Zerosmoke, while another test subject says the magnets were too painful to wear (a complaint echoed by other users). Some reviewers posting at say the advertised 14-day free trial is deceptive, complaining that they were charged the full amount before their trial period expired.

In this piece, a Las Vegas reporter asks smokers to try out Zerosmoke. One couple says they stopped smoking for the week they wore the product, while another test subject says "it was just too painful to keep on for the recommended amount of time." The article goes on to compare Zerosmoke to Chantix, a federally approved drug that has been shown to be effective in clinical trials.

As you can guess from the name of this site, not many of the Zerosmoke users posting here are satisfied with the product. One user suggests people "contact the FTC and review the files on hand. There is NO medical or other actual case studies that show there is any evidence what so ever for this to work." Others complain about deceptive marketing practices, with users being charged the full $39.95 before the two-week trial period has expired.

Of the 10 reviews posted here, seven have the lowest possible rating (1 star), while the others are 5-star raves. One user says "the only people this product is going to help are the hopelessly suggestive and the predators that profit from selling to the suggestive." More practically, he adds that the magnets are "incredibly light, small, hard to see, and very easy to lose."
