Coleus Forskohlii: Uses, Side Effects, Interactions, Dosage and Supplements

Coleus Forskohlii

Coleus Forskohlii (Forskolin)

Coleus Forskohlii is an herb traditionally used in Ayurvedic medicine which has been marketed as a fat burner in recent years. The active ingredient in Coleus Forskohlii is known as Forskolin, which it is often called.

Uses of Coleus Forskohlii

Forskolin has been popular in fat burning supplements in recent years, and you’ll typically find it in both stim-based and stim-free fat burners. 

Forskolin may increase something called cAMP (cyclic adenosine monophosphate), which is a secondary messenger in your cells. In a study, Forskolin was shown to increase total testosterone levels, as well as increasing lean body mass in obese men. 

While the testosterone increase sounds nice, it was not too significant. The lean body mass increase however was more notable, and shows some promise. 

Forskolin was also shown to be potentially effective when combined with Yohimbine according to a study. This was done on women, and Forskolin and Yohimbine were combined in a cream. Another study done on women with Forskolin showed insignificant weight loss results, but there was a noted decrease in hunger and fatigue, and is was noted that is may have helped mitigate weight gain. The study used the same amount of Forskolin (250mg standardized to 10% Forskolin, twice per day) as the one done on males. This may mean that Forskolin may be better suited for males. Either way, there certainly needs to be more research done on Coleus Forskohlii.

Of course, we have to mention that if you ever plan on taking Forskolin for the purpose of weight loss, it must be combined with proper diet and exercise. While the studies have certainly shown promise, it is too early to call Forskolin proven.
