Lipo 6 (Ephedra Free) Fat Burner Review: Does Lipo 6 Work?
 In the face of the ephedra-ban, Lipo 6 has received a bit of a facelift. This new Lipo 6 is not significantly different than the old version, other than the fact that the ephedra has been removed.
Interestingly enough, I see two variations of the ephedra-free Lipo 6 for sale online, each one with a slightly different formulation . Since I don't know which version you're getting, I'll cover all the ingredients here. Keep this in mind as you proceed.
OK, Let's take a closer look at the ephedra free Lipo 6 compilation and evaluate the ingredients...
i) Synephrine (citrus aurantium extract): Although common to many fat burners, there isn't a heck of a lot of evidence that synephrine -- a chemical "cousin" to ephedra -- is particularly effective for weight loss. There is some evidence showing positive effects, but that was when it was combined with caffeine and St. John's Wort. To emphasize this point, check this extract about Citrus Aurantium (synephrine) from this PubMed abstract...
"An extensive search of MEDLINE, EMBASE, BIOSIS, and the Cochrane Collaboration Database identified only 1 eligible randomized placebo controlled trial, which followed 20 patients for 6 weeks, demonstrated no statistically significant benefit for weight loss, and provided limited information about the safety of the herb."
This study (Obes Rev. 2006 Feb;7(1):79-88) concludes...
"While some evidence is promising, we conclude that larger and more rigorous clinical trials are necessary to draw adequate conclusions regarding the safety and efficacy of C. aurantium and synephrine alkaloids for promoting weight loss."
ii) Caffeine: a mild thermogenic (fat burner) that also promotes mental alertness, caffeine works best when combined with ephedra or, as more recently shown, green tea. Of course, there's no ephedra in this version of Lipo 6. However, preliminary studies indicate it may work synergistically with synephrine to increase its fat burning effect.
iii) Guggulsterones: the standardized extract of a resin of a tree native to India. This resin has been used in Ayurvedic medicine for centuries. A
study published in The Journal of Associations of Physicians
in India in 1989 showed this substance to have a powerful effect
in decreasing blood fats (called triglycerides) AND LDL cholesterol
(that's the "bad" cholesterol), while elevating levels
of the good cholesterol "HDL."
Guggulsterones may also stimulate the thyroid gland. This may result in a positive
effect upon the body's main thyroid hormones, T3 and T4.
Your version of Lipo-6 may also contain...
iv) Coleus Forskohlii: traditionally to
treat asthma, overweight, hypothyroidism, and high blood pressure.
It has also been shown to help prevent the formation of blood
clots by preventing platelet aggregation.May also have a positive effect on increasing cyclic AMP (a cell regulating compound) in the body. Increased levels of cAMP can raise thyroid hormone levels and spur further weight loss.
While there is some evidence (Journal of Obesity Research August 2005, "Body Composition and Hormonal Adaptations Associated With Forskolin Consumption In Overweight and Obese Men") indicating this ingredient may be beneficial for weight loss, the results were not overwhelming.
v) Bioperine: the patented extract of the black pepper and long pepper berries harvested in India. Bioperine's value is that it has been established to enhance the bioavailibility of certain supplements through increased absorption. In other words, when combined with Bioperine, numerous vitamins, minerals, amino acids and anti oxidants are more efficiently absorbed and utilized in the body.
vi) Yohimbe: The standardized extract of the bark of the African Yohimbe tree, this compound is often used as a natural aphrodisiac. It is also sold as a drug (in the U.S., a popular brand is Yohimex containing 5.4 milligram of yohimbine hydrochloride per tablet) and is used to treat impotency, dilate the pupil of the eye, and stimulate fat loss. Because it can cause unpredictable effects on blood pressure, Yohimbe should be approached with caution.
According to the US Food and Drug administration...
Yohimbe is a tree bark containing a variety of pharmacologically active chemicals. It is marketed in a number of products for body building and "enchanced male performance." Serious adverse effects, including renal failure, seizures and death, have been reported to FDA with products containing yohimbe and are currently under investigation.
The major identified alkaloid in yohimbe is yohimbine, a chemical that causes vasodilation, thereby lowering blood pressure. Yohimbine is also a prescription drug in the United States. Side effects are well recognized and may include central nervous system stimulation that causes anxiety attacks.
At high doses, yohimbine is a monoamine oxidase (MAO) inhibitor. MAO inhibitors can cause serious adverse effects when taken concomitantly with tyramine-containing foods (e.g., liver, cheeses, red wine) or with over-the-counter (OTC) products containing phenylpropanolamine, such as nasal decongestants and diet aids. Individuals taking yohimbe should be warned to rigorously avoid these foods and OTC products because of the increased likelihood of adverse effects.
Yohimbe should also be avoided by individuals with hypotension (low blood pressure), diabetes, and heart, liver or kidney disease. Symptoms of overdosage include weakness and nervous stimulation followed by paralysis, fatigue, stomach disorders, and ultimately death. |
There's also the issue that the vast majority of commercial yohimbe products are largely devoid of effective levels of the compound. While a few studies bear out Yohimbe's positive effect on impotence, data proving its worth as a fat burner is not as impressive, althought there is some (Isr J Med Sci. 1991 Oct;27(10):550-6).
And your version may contain...
vii) Carnitrex: Lipo 6's name for carnitine. Carnitine plays a vital role in escorting fatty acids to the cell's mitochondria (the energy furnace of the cell), and for that reason is included in many fat burners. Unfortunately, most studies do not validate l-carnitine's effectiveness as a fat burner. Furthermore, studies performed with carnitine involved multi-gram doses. The 100 mg in this compilation is little more than window dressing. Nonetheless, carnitine is a pretty good supplement for other reasons. A full review of l-carnitine is available here!
Bottom line on Lipo 6?
Even though I'm not a fan of yohimbe, the new ephedra-free Lipo 6 is probably on par with competitive fat burner products. That certainly does not mean you'll find the weight melting off you, should you decide to try this product. And it doesn't mean it's a winner. The end conclusion is almost always the same...
If you make the appropriate changes to your diet and lifestyle, you may find Lipo 6 helpful. If you're not willing to make those changes, this product will do little for you.
On another note, Lipo-6 is a product that seems to be very popular with our visitors. Feedback on the product is largely positive, with most people being satisfied with their pruchase, and some even highly recommending it. of course, not all feedback is genuine, but most of this appears to be so. Anyhow, if you're interested in purchasing Lipo 6 I highy recommend you...
