Irvingia gabonensis (IG) is the Latin name of the tree grown in Central and West Africa that produces a fruit similar to a mango and nicknamed African mango, wild mango, dika nut, or bush mango.

In areas where IG grows, its flesh is widely eaten. But it's the seed or nut (fresh or dried) that contains the supposedly powerful ingredients. Sold almost exclusively online, the seed extract comes in powder, liquid, and capsules.


What Are the Claims?
Some web sites claim that the high soluble fiber content of IG seed can melt away belly fat and trim waistlines. It's often combined with other ingredients such as green tea and marketed as a fat-burning supplement.
