There are a number of factors that can contribute to the accumulation of excess fat in the body. As humans age, cells in the brain becomes more resistant to Leptin, a hormone which notifies the brain that the stomach is full, thus enabling you to eat more than your body requires. Another cause is the overactive activity of the enzyme glycerol-3-phosphate dehydrogenase, which catalyzes the conversion of glucose into triglycerides which in turn, cause the size of fat cells to increase. Now you can combat the onset of middle-age weight gain with Integra-Lean Irvingia; an all new product from Life Extension.

Integra-Lean from Life Extension utilizes the African herb Irvingia, which has been shown to help aid weight loss, and help prevent weight gain. Irvingia is believed to help suppress fat-converting enzymes and reduce carbohydrate absorption by inhibiting the amylase digestive enzyme therefore helping to reduce the amount of carbohydrates absorbed as sugars. Several clinical studies have shown Irvingia to be shockingly effective. In the last placebo-controlled human study, people taking Irvingia lost up to 28 pounds in 10 weeks without changing their diets.


  • Helps Regulate Appetite
  • Inhibits Fat-Conversion In The Body

  • Successful Weight Loss

I have been taking it for 10 days. I notice a big difference in my appetite. I have lost 4" around my mid section. I have lost 10 lbs. since January 9th. I do not exercise a lot. Maybe twice a week. I have already received my second bottle to be ready for it. I am on Weight Watchers also. Love both!!!!! Keep taking it. It isn't meant to take and then eat 3,000 calories a day. It is meant for someone who is trying to eat healthy and keep calories to a minimum. I love it so far!!!!

I have used this product with at least 25 patients and have had consistently good to excellent results. Weigth loss has been 20-42 pounds over a 10 week period. Women on average lost more fat versus men. The weight lost was 80% fat. I would recommend this formula.

I actually gained weight using this and eating less. I have been using it for 45 days eating less but gained 4 lbs. My friend did lose some fat around his waist but no weight loss.

i have been taking the integra-lean now for 8 weeks and i have not lost any weight at all, in fact i have gained 6 pounds. i called life extention about not losing any weight on this product and they replied to me that they have been getting numerous concerns from customers also not losing any weight. they couldn't tell me why but they referred me to their magazine article about all the positive things and how it works for everyone. what they don't mention is why it doesn't work for everyone. this is a waste of money at least for me. lorraine
