Syntrax Fyre Review And Information: Does Syntrax Fyre Work?

The Syntrax Fyre fat burner sports 8 ingredients, all packed into a 505 mg proprietary blend. I'm not a huge fan of "proprietary blends," since they disguise the true amount of each ingredient in the formula. This, of course, makes it difficult to accurately assess the product for efficacy.

Nonetheless, let's have a closer look at the Syntrax Fyre formula. What's in it?...

1) Velvet bean extract (standardized for L-Dopa): Thought to be useful for the treatment of Parkinson's disease because it contains a precursor (l-dopa) to the neurotransmitter dopamine.

Dopamine is associated with the "pleasure system" in the brain. Theoretically, supplementing with a dopamine precursor like l-dopa may increase feelings of well-being. Unfortunately, the large majority of l-dopa is metabolised by the body, and only a tiny percentage crosses the blood-brain barrier and gets converted to dopamine. When l-dopa is given as treatment for Parkinsons, it is given with a drug like benserazide or carbidopa to prevent its being metabolised by the body.

When supplied like it is here, it is unlikely to have much effect on dopamine levels, and mood improvement.

Animal studies indicate velvet bean extract may have the ability to lower glucose levels as well, but then again... this effect has not yet been demonstrated in humans.

2) Coffee bean extract (standardized for caffeine): Caffeine is a thermogenic aid common to most fat burners, and found in foods like coffee, chocolate and sodas. One study shows that the combination of caffeine and green tea (as found in Fyre) is especially helpful for weight loss (Obes Res. 2005 Jul; 13(7): 1195-204).

3) Green Leaf Tea Extract (standardized for catechins and EGCG): There's plenty of evidence that green tea exhibits characteristics beneficial for weight loss (see Mol Nutr Food Res. 2006 Feb;50(2):176-87, Am J Clin Nutr; 81:122-129, Journal of the International Association for the Study of Obesity. 2000 Feb;24(2):252-8, The American Journal of Clinical Nutrition. 1999 Dec;70(6):1040-5). It's a good addition to any fat burner -- a "no brainer" actually.

4) Coleus Forskohlii (standardized for forskolin): While the effects of coleus forskohlii and a corresponding positive effect on weight loss have been established in one study (Journal of Obesity Research August 2005, "Body Composition and Hormonal Adaptations Associated With Forskolin Consumption In Overweight and Obese Men"), the results were not overwhelming.

5) Barberry Bark Extract (standardized for berberine): An interesting ingredient to be sure, and one not often found in your typical fat burner. Berberine has anticonvulsant, hypotensive, antifibrillatory, antiarrhythmic and spasmolytic characteristics.

6) Ginger root (standardized for gingerols): Ginger is often used in supplements for its anti-nausea properties, as well as its ability to aid in digestion. More interestingly, gingerol is a chemical relative of capsaicin. You may have heard of capsaicin -- its what gives chili peppers its spiciness. Some speculate ginger root extracts may increase the body's heat production and increase thermogenisis, or fat burning. So far, there is limited clinical evidence to support this theory.

7) Bergenia Root Extract (standardized for bergenin): Bergenin is known for its ability to lower LDL (i.e., the "bad") cholesterol (see J Lipid Res. 2006 Oct;47(10):2134-47. Epub 2006 Aug 2).

8) Yohimbine: A few studies bear out Yohimbe's positive effect on weight loss (Isr J Med Sci. 1991 Oct;27(10):550-6) but its effects are hardly earth-shattering.

So what's the bottom line on Fyre?

Well, the combination of green tea extract and caffeine is a good one, and adding yohimbe and coleus forskohlii into the mix doesn't hurt Fyre either. The remainder of the ingredients are certainly interesting, but its doubtful they add a ton of real value to this compilation -- there just isn't that much clinical evidence validating their effectiveness.

In other words, Fyre is an interesting product, but its certainly not revolutionary. If you're tempted to try it, remember...

Syntrax Fyre is not a miracle pill. Without the implementation of a proper diet and exercise program, you won't see much in the way of results.
