It has been a while since you started with Integra-Lean Irvingia, how has it worked for you? Any comments about it?

The study referenced here is the 2005 study. I agree, it is full of flaws. For what it is worth, the LEF article focuses more on the 2008 study. I don’t have a link for the new study, but here is a page that does provide a bit of information.

Although this study does not appear to be adequately randomized, I should mention that I know two women who credit Irvingia for controlling their appetite, without any of the jitteryness or side effects of stimulants.

We are following a patient who is using the newer enhanced Irvingia, for weight loss.

I definitely agree with the previous poster that the ‘Disease Prevention and Treatment Book,” is very well written and researched. It is the best book of this type, I have found.

I was on this product Irvingia for more than 10 weeks and I believe it was not the reason for my weight loss. I believe I lost my weight because I lost my mind and workout 5xs a week killing myself. There were no changes in my energy levels, I was always tired I just forced myself to workout because I wanted to lose the weight so bad. No matter what LEF is claiming I was a consumer and it did not deliver for me at all. If that were the case, Ishould have lost more weight. I did everything they said to do, ate healthy food, cut out junk and exercised and took the Irvingia product. Companies say what they do to make money. The only way to lose weight is the old fashion way. PERIOD

Jae, how is the weightloss going with Integra-Lean Irvingia? I just started it. Are you taking only 2 pills a day? It does not tell you when to take them before meals for the best affect.

Thanks for your help!

Life Extension is a good organization. But they do not demand rigor from the studies they comb through. For example, they seem to see no difference between a double-blind, placebo-controlled study versus a simple observation of just one “treatment” group. There IS a difference. This goes hand in hand with their greatest flaw: their bias is that there are lots of beneficial supplements and treatments out there, that if the faintest hint of benefit is shown in even one poorly-designed observation, they’re all over recommending it.

Their recommendations are unlikely to cause harm, but the latest-and-greatest recommendations are likely to be a waste with less benefit than LEF anticipates. Their recommendations with more research backing and longer terms of study (e.g. CoQ10) are much more likely to be worth the money.

I have been taking Irvingia for about 3 weeks and suddenly my blood pressure is way too low. To be fair, I have to say I am on a beta blocker, metoprolol, but it wasn’t this low before. It’s sometimes as low as 75/45. Then I am unable to take the metoprolol which was needed to prevent arrythmias. So I am worried. Has anyone else’s blood pressure gone down so much?

I agree with Lou and others who have observed that the active experimental and placebo control groups do not appear to be adequately randomized, and differ markedly in initial body weight, blood pressure and lipid status. The study published does not explain how subject randomization was performed.

Clearly the more overweight active experimental group would likely experience more weight loss. The placebo group was already at an optimal or suboptimal cholesterol level and ideally would not experience further cholesterol reductions.

The systolic blood pressure decrease in the active group was less than half of the systolic blood pressure decrease in the experimental group.

I also agree the standard errors of measurement from the mean are unusually high and may obscure differences produced by the herbal Irvingia treatment.

Results of the crossover phase of the study were ommitted from the published study. Age and sex demographics of the randomized groups were also ommitted from the publicized study and might help explain the large initial differences in the active and placebo groups.

This study does not appear to have received adequate peer review, prior to publication. Results reported in the study abstract appear to be only partially supported by the full study published at Lipids Health Dis. 2005; 4: 12.
