Zantrex 3 Fat Burner Review


Zantrex 3 is one fat burner that pushes the advertising hype “envelope” into the stratosphere. For instance…

Zoller Labs claims Zantrex 3 will give you “546% more weight loss than the leading ephedrine-based diet pill.”

546%? That’s an oddly precise-looking number. Where does it come from?

Who knows?

I suppose it doesn’t really matter anyway, since there is no “leading ephedrine-based diet pill.” Ephedra alkaloids were banned for use in over-the-counter diet supplements several years ago.

And no, this isn’t an old web page – The Zantrex-3 site was updated in 2011 to include Snooki – the product’s new spokesmodel.  So why not 546%? When you’re comparing your product to one that doesn’t even exist, pretty much any big number will do.

And then there’s this howler…

“Zantrex-3 is a new category of bifurcated weight-loss compounds providing both rapid weight loss and incredible energy combined into a single power-packed Super Pill*. New Zantrex-3 is so powerful you won’t find it in any supermarket next to some “Flintrock” vitamin for kiddies.”

Ok, I guess they’re technically correct about not finding Zantrex-3 in “any supermarket” next to the chewable children’s vitamins. Rather, you’ll have to look for it on a shelf or two over… in such department/supermarket chains like Target and Walmart.

And “bifurcated” weight-loss products that provide energy + weight loss are new??? Since when??? Caffeine has been a mainstay of weight loss formulas since I started this site 14 years ago… it was common then, and it looks like it’s going to stay that way for the foreseeable future. And why not? It’s America’s favorite drug: stimulating, readily available and dirt cheap.

Thus, it should come as no surprise that the Zantrex-3 formula relies heavily on this oh-so-ubiquitous compound. One serving of Zantrex 3 will provide you with more caffeine than you’d obtain from 3 cups of coffee.

Zantrex-3 may be “ephedrine-free,” but with all that caffeine, it’s a distinction without a difference for many: caffeine has many of the side-effects associated with ephedra, so it’s not for everyone (see Zantrex 3 side effects for more on caffeine side effects).

With that said, I want to emphasize that caffeine is a proven, albeit mild fat burner (see Am J Clin Nutr. 1989 Jan;49(1):44-50, Am J Clin Nutr. 1980 May;33(5):989-97), although it pales in comparison to ephedra (actually it works best when combined with ephedra).

Of course, much of the caffeine in Zantrex 3 is derived from natural sources (like yerba mate, green tea, guarana, cocoa and kola nut) so it is possible you’re getting benefits up and above the caffeine content these herbals provide.

Green tea, for example, (reviewed here) is a pretty exciting compound showing great potential as a weight loss agent, and yerba mate has also been shown to increase metabolism and stimulate weight loss.

Interestingly enough, Zantrex 3 also contains maca root, ginseng, and damiana; herbals that are best known for their ability to work as aphrodisiacs.

Despite this, one study (J Hum Nutr Diet. 2001 Jun;14(3):243-50) showed that the combination of yerba mate, damiana and guarana delayed gastric emptying (leading to increased feeling of satiety) and increased weight loss. However, it is impossible to tell whether or not Zantrex 3 contains a dosage comparable to that used in the study, or whether these ingredients are present as label dressing only.

Schizonepeta (also known as “Japanese catnip”), another ingredient in this compilation, is used in herbal medicine for numerous purposes, although none are validated by any real scientific research, and none are directly related to weight loss (for more on Schizonepeta, click here).

So what’s the bottom line on Zantrex 3?

This product’s massive caffeine content means you will experience more “nervous” energy (lots of jitters, too!), a suppressed appetite (although not suppressed to the extent of ephedra), and an increased metabolic rate (to learn about Zantrex 3 side effects, including some visitor comments, click here!)

Keep in mind too, that Zoller Labs, the manufacturer of this product, has a serious credibility problem. Its parent company, Basic Research, has already been fined by the FTC for making false and unsubstantiated claims about their products.

If you alter your diet accordingly, monitor your caloric intake, and implement a practical exercise program, Zantrex 3 may provide you with an extra edge.

I would caution that this is not a miracle pill. If you don’t intend to make these modifications to your lifestyle, don’t waste your money on Zantrex 3.

I’d also suggest those of you considering using Zantrex-3 should check out what other visitors to this site have said about the product!

Although are many are fans, just as many have experienced serious and frightening side effects. In addition, the product contains enough caffeine that – taken as directed – will very likely trigger caffeine withdrawal symptoms when you (hopefully!) reach your goal and stop taking it.
