Forslean® (Coleus Forskohlii) for Weight Loss

Forslean®is a proprietary form of Coleus forskohlii manufactured by the Sabinsa corporation. Coleus forskohlii is a perennial plant of the mint family that has been used in Ayurvedic traditional medicine for ages.

Although some evidence suggests its critical constituent (called “forskolin”) may be useful in the treatment of asthma (see Eur J Pharmacol. 1985 Apr 23;111(1):1-8) and even cancer, it is most often retailed as a weight loss aid—either on its own, or as part of a larger formula.

There is some justification for this.

For instance, there have been a couple human-based studies performed on the anti-obesity effects of Coleus forskohlii, and while positive, were hardly earth shattering. This study, performed on “mildly overweight women”`concluded…

“Results suggest that CF does not appear to promote weight loss but may help mitigate weight gain in overweight females with apparently no clinically significant side effects.”

A further study—this one performed on men—had better results. It concluded…

“Oral ingestion of forskolin (250 mg of 10% forskolin extract twice a day) for a 12-week period was shown to favorably alter body composition while concurrently increasing bone mass and serum free testosterone levels in overweight and obese men. The results indicate that forskolin is a possible therapeutic agent for the management and treatment of obesity.”

Of course, the results were not miraculous by any means; participants lost anywhere from just under 10 lbs. to 22.5 lbs in the 3-month study.

That equates to .83 lbs to 1.88 lbs. per week, well within the realms of what you can expect by simply incorporating a smart diet and exercise program into your daily regimen.

Still, if you’re looking for a stimulant free fat burner to use, this is an option to consider.

Coleus forskohlii is included in many popular weight loss supplements (usually in the patented Forslean format) but is too often underdosed.

Buying it on its own from a reputable retailer is the best option, as it ensures you can take the optimal dosage. We recommend the Life Extension Forskolin product from

Remember, to duplicate the dosage used in the studies you will need to take in 50 mg of active forskohlin per day. With the Life Extension product, that equates to 5 capsules per day—which means a single bottle will last you 12 days.

If you don’t like swallowing that many pills, Nature’s Plus Coleus Forskohlii from is another option (use the coupon code FAT259 to receive $5 off your first order). You will only need to take two of these daily to obtain the necessary dose, and a full bottle lasts 30 days.
