Yohimbine is a substance found in the bark of Pausinystalia yohimbe, a tree found in Central and Western Africa.
It’s commonly used as an aphrodisiac, but it also has properties that may help you burn fat.
Yohimbine works by blocking receptors called alpha-2 adrenergic receptors.
These receptors normally bind adrenaline to suppress its effects, one of which is encouraging the body to burn fat for fuel. Since yohimbine blocks these receptors, it can prolong adrenaline’s effects and promote the breakdown of fat for fuel (
A study in 20 elite soccer players found that taking 10 mg of yohimbine twice daily helped them shed 2.2% of their body fat, on average, in only three weeks.
Keep in mind these athletes were already quite lean, so a 2.2% reduction in body fat is significant (
Also, animal studies have shown that yohimbine may help curb appetite (
Nonetheless, more information is needed on yohimbine before it can be recommended as a go-to fat-burning supplement.
Furthermore, because yohimbine keeps your adrenaline levels elevated, it may cause side effects like nausea, anxiety, panic attacks and high blood pressure (
It also can interact with common medications for blood pressure and depression. If you take medications for these conditions or have anxiety, you might want to avoid yohimbine (
Summary: Yohimbine may help you burn fat by keeping adrenaline levels high and blocking receptors that normally suppress fat-burning. However, it can cause unpleasant side effects in some people.
