Review of African Mango Irvingia gabonensis and Weight Loss

Posted by on Mar 1, 2013 in Blog | 0 comments

I’ve been getting a lot of questions about African Mango, also called Irvingia gabonensis and whether this fruit can help people lose weight. African mango is similar to the mango’s you’ve probably eaten at some point. So, to help you, I wanted to review it and give people a better idea of what it is, what the research says and whether it might help weight loss. On the web, you may also see African Mango called Bush Mango or Wild Mango. All names refer to its scientific name, Irvingia gabonensis. The extract of African mango that has been used in weight loss research is called IGOB131. This name is sometimes shortened to simply OB131. Keep this in mind as you read this review.
Irvingia gabonensis / African mango research

There is indeed research on Irvingia gabonensis. More precisely there is research on an extract from the seeds of the African mango tree. The extract is dubbed IGOB131. I am telling you this because if you try Irvingia gabonensis weight loss supplements, this is the ingredient that the research was conducted on. Other African mango extracts may not have the same effect.

In one 4 long week study, published in 2005 in the Journal Lipids in Health and Disease, 40 overweight people were given either 3.15 grams of Irvingia gabonensis or a comparable amount of oat bran 30 minutes before meals, in conjunction with a low fat diet. People ate about 1800 calories a day. At the end of this 4 week study, those receiving Irvingia gabonensis lost about 5.6% of body weight vs. those in the placebo group who lost about 1% of body weight. Body fat did not change significantly in either group.

Body fat was measured using bioelectric impedance analysis, a method commonly used in health clubs. This method, while quick and easy to administer, is less accurate than other means like hydrostatic weighing, Bod Pod etc.

Systolic blood pressure (the top blood pressure number) was reduced about 4 points after the 4 week study. This drop in systolic blood pressure could be simply due to the weight loss experienced as opposed to a direct effect of Irvingia gabonensis itself.

In a 10 week study, published in 2009 in the journal, Lipids in Health and Disease, 102 healthy overweight men and women were followed for 10 weeks. People were split into either a placebo group or a group that received 350 mg of Irvingia gabonensis. The Irvingia gabonensis was supplied by Gateway Health Alliances Inc (Fairfield CA).

In those receiving the Irvingia gabonensis extract, body weight, body fat and waist circumference had decreased more than in the placebo group. Those getting IGOB131 lost 28 pounds vs. about 1 pound for those getting the placebo. Body fat was determined using bioelectric impedance analysis.

LDL cholesterol (bad cholesterol), total cholesterol, blood glucose, and C reactive protein were also lower in those who received the Irvingia gabonensis extract.

The weight loss observed in the African Mango group could account for the the decreases in cholesterol, blood glucose and C reactive protein. These things do change when people lose weight. The soluble fiber in the extract may also had an effect on cholesterol levels.

Another study published in 2009 in Lipids in Health and Disease by the same researchers exposed mouse cells to IGOB131 and noted that the compound increased fat cell production of adiponectin. Research finds that adiponectin has anti inflammatory properties and that high levels of adiponectin appear to be correlated with a lower a lower risk of heart disease. This same study noted that IGOB131 inhibited fat cell development as well.
