African Mango Extract – another crock!

African Mango, more hype, less losses

This one has a little more info and potentially basis than the previous post on Raspberry Ketones, as there is an extract from the African Mango (irvingia gabonensis) Seed (Also called Dika Nuts) that does have an effect on weight loss. However it is a very specific extract called IGOB131. Here are a couple of articles from the US National Library of Medicine (a US Government body):

However WebMD has stated that this research is of a poor quality, and one was also sponsored by a supp company I cant find a lot about – may be owned by Dr Oz :lol:, and was carried out on non-Western subjects, local to Cameroon, and on a pretty high cal diet 2700 cals+, which may be skewing the results.

Also as this is pushed by Dr Oz, you can almost bet that it is snake oil again.

What I am also struggling in finding out whether the products the are being pedalled actually contain any IGOB131, and if so whether this is enough to trigger the effects described in this article.

The Claims

The sites I have found for the supplement version make the following claims, as they all seem to:



– SHED INCHES FROM WAISTLINE (well you’re losing weight so this is a given surely – bloody marketing hype)



These claims seem to have some basis (to the extent of the research trials), however until this is ratified with a wider level of independent research it is really difficult to draw a full conclusion.

For obesity and lowering cholesterol levels, a dose of 1.05 grams of crude seed extract three times daily has been used. A dose of 150 mg of a standardized seed extract (IGOB131) twice or three times daily has also been used.  However most of the supps I have seen are not this, they are just African Mango extract, which is probably not the stuff you actually need.  I also have it on first hand authority that having been tried by a colleague I trust, it proved to do Zero when taken as directed, with no other changes to diet.

What is happening

Most of these products work as subconsciously people modify their diet when taking it.  they think they wont have they extra biscuit or slice of cake as they are taking a diet pill.  Any losses are then from the dietary changes, not the pill.

If considering using this stuff, consider the following:

A/. All research has used IGOB131 ONLY. You should look for the quantity of IGOB131 on the label, if its not mentioned…. well you decide. If it contains whole African mango or different extracts it wont have then same effects.

B/. Based on the research best results happen when people take 450 mg of IGOB131 as day (3 x 150mg). Good results will be better when combined with a lower calorie diet (no shit Sherlock)

C/. Weight loss alone could account for the observed changes in total cholesterol and LDL and CRP. Some have attributed the effects of African Mango to its soluble fibre content but I think this may be premature, as personally mine dropped when I lost my fat.

D/. One study showed that Irvingia Gabonensis lowered leptin levels, and this is being used incorrectly as a justification for weight loss. When Leptin is lowered, your appetite increases, so is counter to what is being suggested by the hype. Low leptin is a bugger, and can lead to cravings. I am trying a leptin modifying diet at the moment, that promoted higher leptin in the mornings, and the effect on my cravings has been great. I wouldn’t want low leptin levels.


So as I said I am really not sure on this one. It has been around a while, but gaining popularity through Dr Mehmet ‘Snake Oil’ Oz. This will mean that as supplies are harder to come by, different extracts are bound to be used rather than the one that is key. This has been seen before with Synephrine and Bitter Orange Extract.

Best bet is to just sort out your diet and train more…
