Why is it that so few diet formulas are backed by real science? Let’s take a look at forskolin to see if there’s anything behind it. Our in-depth review examined the side effects, effectiveness as an ingredients, clinical studies and customer service quality. Moreover, we took a close look at numerous user responses and comments on other Forskolin reviews. We then compressed and summarized to give you the info you need.
What is Forskolin?
Forskolin is an extract of a plant in the mint family that grows in Southeast Asia. Forskolin is the main bioactive ingredient of the plant Coleus forskohlii, which has been used for years as a fat-burner, and weight-loss supplement. According to various forskolin reviews, the addition of this extract to the daily diet of a human being is supposed to increase testosterone levels while reducing inflammation and protecting against cancer. Additionally, forskolin consumption allegedly increases the level of a molecule called cyclic adenosine monophosphate (cAMP) at the cellular level. This molecule has been widely studied because high concentrations of it increase lipolysis in the body. While more research is needed, initial results seem promising.

As a bioactive ingredient of a plant, forskolin extract is a natural medicinal compound that can be found commercially in a variety of brands. Although more research is needed, forskolin extract as a lipolysis facilitator has preliminary proven to be a good fat-reducer. 
How Did Forskolin Start?
The plant has been used for centuries in Ayurvedic medicine to cure numerous central nervous system, gastrointestinal, and cardiovascular ailments and diseases. Traditional usage claims also include lung and urinary health. Although indigenous health care practitioners claim all these properties are true, the most widely known use of this plant in its native region is the treatment of asthma. This was tested by traditional western medicine research, which found increased levels of a compound known as cyclic AMP.  The natural forskolin found in the plant would relax the muscles that surround the bronchial tubes and allow users to breathe easier. The use of the forskolin for weight loss came later, as a result of some testing that discovered that cyclic AMP would also help with lipolysis on humans. Lipolysis aids users in the dissolution of fat in the body.
The natural forskolin found in India, Nepal and Thailand comes from a plant, but not all parts of the herb are used. The highest concentration of forskolin can be found in the roots. There are no studies at this time that indicate that the rest of the herb has any medical use or benefit. 
This has been the most traditional use of the plant; to treat asthma. NYU Langone Medical Center hosted two controlled trials and found that forskolin could potentially be a good supplement to treat asthma. The key benefit was that the cells releasing histamine received stabilization from correct forskolin dosage,relaxing the muscle tissues in the throat, making it easier to breathe.
Glaucoma is an eye issue that can blind those who suffer from it. Again, ancient Ayurvedic medicine used the plant to treat those with vision problems and it was NYU Langone Medical Center that picked up that information to test the possible effects on humans. Using concentrated forskolin eye drops, researchers found that it successfully reduced the pressure in the eyes. Although more studies need to be done, there is a lot of optimism from both doctors and patients. The grade given to Coleus forskohlii by practitioners, in terms of efficacy to treat glaucoma, is a very optimistic B.
While ancient cultures weren’t as obsessed with weight-loss as modern Westerners are, the weight loss benefits might be the most influential one in the commercialization of this root extract. Forskolin weight loss is associated with lipolysis, which is the fat-burning process of the body. A small, blind study was recently undertaken by the Memorial Sloan Kettering Cancer Society and published in the “Journal of the International Society of Sports Nutrition” on their December 2005 issue. The research found that 23 females who were given the concentrated extract did not lose weight, but the forskolin did help in the prevention of weight gain. The women who took the test were mildly overweight. So, according to recent evidence, the effectiveness of forskolin for weight loss is not proven, but it may help to prevent the weight gain.
Other Potential Benefits
According to ancient Ayurvedic sources as well as recent studies, there are many other applications for Coleus Forskohlii.
- Congestive Heart Failure
- According to Tufts Medical Center, it can also be useful in the treatment of the following less dangerous ailments:
- Menstrual Cramps
- Bladder pain
- Irritable Bowel Syndrome
- Urinary tract infections
- Erectile dysfunction
According to several studies, supplementation of forskolin can help human body in:
- Lipolysis, which reduces fat
- Reduction of eye-tension, which helps those who have glaucoma
- Stabilization of cells releasing histamine and relaxing throat muscles, allowing asthmatic people to breath better
Unsubstantiated benefits include cancer prevention, hypertension and congestive heart failure among many others.
According to forskolin reviews, the extract itself is the main bioactive component of a plant called Coleus forskohlii found in Southeast Asia, India and Nepal. Other than the root, where this compound is concentrated, the herb has no additional use. Most products found on the market today provide a highly concentrated dose of this extract and not much more, because it is thought to be herbal medicine. Marketing about this product focuses on the purity levels and concentration of each pill, stating deliberately that each pill contains no other ingredient. 
Does Forskolin Work?
There have been several studies that prove the effectiveness of forskolin with regard to its many uses in traditional and western medicine. As reported by these studies, the fat-loss factor was successfully tested on males (“Obesity” journal, 2005), but not on females (“Journal of the International Society of Sports Medicine”, 2005), in whom it was only proved that it prevented fat gain. All other uses were studied using blind tests over very reduced populations, and although there were very promising results, results are not definitive.
Some controversy surrounding the weight-loss properties of forskolin involved Dr Oz. and it got as far as a Senate Hearing after the TV personality called the forskolin vitamin a “miracle flower” in front of millions of viewers with no substantial medical data to back it up. 
Since it is a bioactive compound with many uses, we will take a look at its effectiveness in its different applications:
This is the most frequent Forskolin review available, not because weight loss is the most critical issue it can help with, but because of the commercial value of weight loss supplements. With regard to weight loss, there are two different studies available:
- A study published in December 2005 by the “Journal of the International Society of Sports Medicine” found no positive benefits in weight-loss by the intake of forskolin, but it did help in the prevention of fat gain.
- A different study published in 2005 by the journal “Obesity”, studied in males, found that those who were given forskolin with a twice-a-day frequency showed some beneficial changes in their body composition, including increased bone mass and reduced body fat.
This is one of the most researched uses of forskolin since it is the primary use in its countries of origin (India, Nepal, Thailand, Southeast Asia). It relaxes throat muscles and helps stabilize the cells that release histamine. According to two studies, forskolin was successful in reducing asthma symptoms and preventing asthma attacks.
This is an ocular disease that eventually blinds those who suffer from it. According to two clinical tests, forskolin eye drops concentrated at 1% could reduce ocular pressure in healthy males.
High blood pressure can lead to many ailments and sometimes death. According to two trials, after 12 weeks in one study and 2 months in the other, results were favorable as both groups experienced drops in blood pressure.
Preliminary testing of the bioactive compound to treat several affections both in vitro and on living specimens have some really encouraging results. Despite this good start, further studies are needed to prove the benefits of this extract. 
Details On Forskolin And Weight Loss
Forskolin and its weight loss benefits were tested on different occasions with different results. The lipolysis capabilities of forskolin are an intriguing benefit, but as far as medical studies go, there is not enough evidence to definitively call forskolin a fat burner. Dietary supplements such as Forskolin Fuel and Forskolin Slim claim that it boosts metabolism, forcing the human body to burn more fat than usual, but there’s no real evidence to back these claims.
How To Take Forskolin For Weight Loss
Forskolin is marketed commercially as pills, containing anywhere from 125 mg to 500 mg and is usually taken twice a day. According to supplement companies, taking forskolin supplement pills such as Forskolin Fuel and Forskolin Slim has to be done daily, and should continue after weight-loss as maintenance.
How To Use Forskolin
Forskolin is available for use in 4 ways:
- Intravenous – Intravenous presentation of forskolin is usually for non-commercial use and is obviously liquid. This is mainly used by doctors and health professionals in a clinic environment for a rapid absorption when a heart condition known as idiopathic congestive cardiomyopathy is presented by a patient.
- Powder – Patients who suffer asthma can use forskolin in powder form, under prescription, with a Spinhaler inhalator.
- Drops – When treating glaucoma, a 1% forskolin solution as a drop for the eyes is used.
- Pills – The most widely available form. Supplements can be found in most major online retailers like Amazon. Pill form is employed as a fat-loss supplement.
The dosage varies depending on the ailment being treated. Most commonly, the dose for weight-loss is 500 mg a day.
Where to Buy Forskolin
When buying pill supplements, Amazon and other online retailers offer a very wide array of brands and manufacturers. In most cases, the product contains only pure forskolin, which is a natural compound.
Potential Forskolin Side Effects
Since forskolin is an extract taken from a plant root, with little or no chemical processing involved, it is supposed to be quite harmless to humans. However, it is advised to visit a doctor before starting forskolin supplementation. According to The Memorial Sloan Kettering Cancer Center, the reported forskolin side effects after testing were:
- low blood pressure
- irregular heartbeat
Forskolin in its powdered version (for inhalation) can cause throat irritation, tremor, cough and agitation/restlessness. Also, in its eye drop form, it could cause stinging in the eyes.
Is Forskolin Safe?
Forskolin Product Warnings
Is forskolin safe? The answer is yes for healthy individuals, but the product has some contraindications, precautions, and warnings, particularly with persons having other medical conditions and interactions with other medications.
It is contraindicated in pregnant women. Forskolin might slow down the growth of the fetus or even stop it at higher doses. Breastfeeding could also create risk for infants.
Heart Disease and Bleeding Disorders
Recent evidence states that there is a risk of bleeding in some individuals after the intake of forskolin. Since it lowers blood pressure, forskolin might interfere with those being treated for blood vessel or heart conditions, making them worse. People taking these drugs should not take forskolin:
- Blood Thinners
- Calcium channel blockers
Low blood pressure
Forskolin is contraindicated for those with a low blood pressure because it is known to reduce blood pressure.
It is believed that forskolin intake increases stomach acid, making forskolin supplementation a very painful experience for those with ulcers
According to Sloan Kettering, the supplement can provoke cyst growth in those with polycystic kidney disease.
Since forskolin interacts with lipids and blood sugar levels it is contraindicated for those suffering from any type of diabetes.
Taking forskolin in pill form for weight-loss purposes is perhaps the most dangerous since it can be purchased anywhere without medical supervision. According to the forskolin GNC review available on the site, it is an awesome product for weight loss, but you should always check with a doctor before taking forskolin.  
Any Forskolin Lawsuits?
The only known incident between the legal system and forskolin weight-loss supplements was the interaction with Dr. OZ and the US Senate. Dr. Oz was scolded for the lack of medical evidence when he called forskolin a “miracle plant”. Other than that interaction, which was explosively popular with huge media coverage, there are no incidences of forskolin being a part of lawsuits by consumers. It is not rare to find reviews stating that it is a fraud or a non-effective supplement, but there are no records of any lawsuit involving forskolin.
There are a plethora of products from natural sources that claim to be the perfect supplement for weight loss. Let´s take a look at them:
