Rev XP Fat Burner Review: Does RV XP Work?

Rev XP boasts "targeted 6-pack" technology, and the strongest fat-loss support formula on the market. I don't know about that, but there is a ton of caffeine in this product, enough to make the average person jitter his or her way happily (or not so happily depending on how sensitive you are to caffeine) through the day.

NxCare's Rev XP formula does contain some fat loss winners, and a couple of good combinations. So what's in Rev XP?...

1) Green tea: a good, no-brainer addition to any fat burner, there's some evidence that green tea offers some real, tangible benefits as a potent weight loss ingredient. A full review is available here! Take note that's there's a good dose of green tea in this product, providing the caffeine content of approximately 2.5 cups of coffee.

2) Caffeine: A decent thermogenic on its own, one study suggests the combination of green tea and caffeine has additional benefits (Obes Res. 2005 Jul; 13(7): 1195-204), which provides an additional punch to this product. Caffeine is actually part of the patented 6-ingredient blend, but I've included it here with the main ingredients because the label indicates over 350 mg per serving -- that's equivalent to over 3 cups of coffee's worth!

3) Cocoa bean extract: standardized for theobromide, an xanthine-derivative of caffeine, this ingredient has mild stimulating effects. It's effect on weight loss has not been effectively demonstrated at this time.

4) Yerba mate: commonly used as a diuretic and an energy enhancer, mate contains both caffeine and other xanthines also common to coffee. As such, this ingredient ramps up the caffeine content of this formula even more.

5) Dandelion root extract: included as a diuretic in this formula, helping to reduce excess water weight. A full review of dandelion root is available here!

6) Patented 6-ingredient blend: includes an undisclosed amount of the following ingredients...

• Clary Sage Extract: standardized for forskolin, a compound which may have a positive effect on the speed of the intercellular processes in the body.
• 4-Hydroxyisoleucine: derived from fenugreek, this ingredient may a positive effect on insulin function.
• Ginseng: a common adaptogen
• Amentoflavone: derived from ginko biloba, which contains several flavanoids, which tend to offer general health-benefits.
• Piper Nigrum: black pepper, usually included to improve the overall efficiency of the product formula.
• Caffeine: see above

Special note: the preceding represents the U.S. formula... the Canadian version is slightly different.

Bottom line?

This is a very potent, caffeine rich formula. Anyone who has a caffeine sensitivity might be well advised to avoid Rev XP. Everyone else would be best suited to start with the smallest dose possible to access your tolerance. Please note that although the combination of green tea and caffeine has been clinically shown to promote weight loss, unless you make significant changes to your diet and lifestyle, it is unlikely Rev XP will do anything for you.
