What You Should Know
Life Extension Integra-Lean Irvingia focuses on leptin levels in obese and overweight individuals to increase weight loss and reduce fat. A study is referenced supporting the use of the main ingredient for weight loss. After taking a look at the study, we agree it looks like the results are positive, but hidden in the words are complaints of several side effects.
List of Ingredients
Integra-Lean Irvingia Gabonesis Proprietary Extract, Maltodextrin, Vegetable Cellulose, Rice Flour, Stearic Acid, Vegetable Stearate, Silica.
The only ingredient in Life Extension Integra-Lean Irvingia is Irvingia Extract. The official name for the extract is Irvingia Gabonesis Seed and has been clinically studies for weight loss. During the study, participants were given 3000 mg of the extract every day and weight loss was noted. However, in addition to the slight weight loss, dieters also complained of increased hunger, stomach problems and dizziness. The dieters were subject to a reduced calorie diet of 1800 calories per day, which could account for the weight loss. No other positive studies could be found for the ingredient.
It is more likely that the weight loss associated with this ingredient is actually due to calorie reduction. The body needs a specific number of calories per day to perform basic organ functions. If the dieter consumes less than that number, weight loss will occur. In the case of the Irvingia study, the 1800 calories consumed per day could have been low enough to cause weight loss.

Life Extension Integra-Lean Irvingia is not a supplement we would suggest a dieter try. The long list of complaints by participants in the noted study – supposedly there to support the supplement – is enough to leave us wondering if the supplement is safe.
Proven ingredients are available to dieters who want to lose weight the right way, naturally. These ingredients include green tea and caffeine, both of which have clinical studies to support weight loss without severe side effects like dizziness.
