Today, Coleus forskohlii is used as a fat burning supplement. The main bioactive element in Coleus forskohlii is called forskolin. Through forskolin, Coleus forskohlii supplementation may increase testosterone, and protect versus cancer as well as swelling. Further research study is needed to confirm these impacts, given that forskolin is most often used as a research tool artificial insemination, or outside the body, like in a test tube or petri dish. Forskolin may act differently inside the body. Forskolin increases cellular levels of an enzyme called cyclic adenosine monophosphate (cAMP). Elevated cAMP levels are connected with increased rates of fat loss, and could improve the impacts of other fat burning substances. Forskolin is still being researched for its effects on testosterone and fat loss, but preliminary evidence is promising.
