Does Zantrex-3 Work for Weight Loss?
Zantrex
®-3 is one of the best-selling weight loss supplements. However, this probably has more to do with advertising than with the actual effectiveness of the product.
Zantrex-3 has not been proven to be effective for weight loss.
The Zantrex-3 Web site claims that this product has been scientifically proven to cause weight loss and provide energy, based on the results of two studies. Unfortunately, the names of these studies are not provided, which makes it difficult for most people to locate and examine these studies. To make things easier, we have located and examined these studies for you.
One study suggested that three of the ingredients in Zantrex-3 (yerba mate,
guarana, and
damiana) may slow the emptying of food from the stomach and may help people lose weight. If you look closely at this study, you will notice that these herbs did not help with weight loss after 45 days (up to one year later, people had not lost any more weight, on average, even though they were still taking the herbs).
When reading about the second study, you might conclude that Zantrex-3 contains a breakthrough energy drug. The Web site gives the impression that trimethylxanthine is an exotic and shockingly effective drug. Nowhere on the Web site is it mentioned that trimethylxanthine is just a fancy name for caffeine. The second study that "proves" that Zantrex-3 works is just a study that shows that caffeine helped Navy SEAL trainees stay alert during training exercises.
Zantrex-3 itself has never been studied in any (published) studies.
