Forskolin For Weight Loss

The Dirty Little Secret Behind this “Magic Belly Buster”.

Forskolin supplements seem to be the latest buzz in weight loss. Called the “magic belly buster”, forskolin has been apparently endorsed by TV talk show hosts and celebrity doctors as the hottest new miracle cure for weight gain.

Can forskolin help you lose weight? Can it bust your belly fat? Here are some facts behind forskolin which you won’t get from those who endorse it. We’re here to set the record straight.

Forskolin is a most potent aromatase inducer. Aromatase is the enzyme that converts testosterone into estrogen which is a fat storing hormone. Excess Estrogen has been linked to female disorders and feminization of men. Meaning: the use of forskolin should raise some serious concerns. Here is a quote from my book, The Anti-Estrogenic Diet (p. 152)

“Note that forskolin (derived from coleus forskolii), a compound used by the fitness industry to promote fat loss, should be consumed with caution. Forskolin is a potent estrogen promoter due to its cAMP-stimulating and aromatase inducing effects. Researchers have been using forskolin as a standard aromatase-promoting agent for comparative purposes.”

    What are your thoughts on this study then? http://www.ncbi.nlm.nih.gov/pubmed/16129715
    "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. "

    Paul, the research you referred (done about 10 years ago) is a short term study which does not reflect the potential side effects of long-term use of forskolin. Note that similar to the case with soy isoflavores the research data behind forskolin is contradictory. Many companies have been jumping on the commercial wagon of forskolin (and soy isoflavores) claiming multiple health benefits, but in the end of the day, both soy isoflavores and forskolin have shown to act as aromatase inducers. Our purpose was to put the record straight and reveal the other side of the story.
