is derived from roots of the plant
. The herb has been used to treat a variety of health problems including e
nhancement of weight loss
. In a study published in Obesity Research this month, researchers put it to the test in a randomized, placebo-controlled clinical trial in overweight men. Half the subjects received forskolin
(250 mg of 10% extract twice per day) and half a placebo pill. After 12 weeks of supplementation forskolin resulted in improved body composition. This was due to a
greater fat loss
increased lean body mass and bone mass
. Forskolin also led to a significant increase in free testosterone levels compared to placebo. The findings provide evidence for a role of Coleus forskohili
in the improvement of testosterone levels and weight loss. This will surely be followed up with additional work to validate the study findings and determine how forskolin works.
