Forskolin Review - Does This Ingredient Work? Are conflicting reviews and lack of results deal breakers?
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. We then compressed and summarized to give you the info you need.
What is Forskolin?
To begin, forskolin is a chemical that comes from the roots of the coleus forskohlii plant. This natural extract has been used for many centuries to treat conditions such as high blood pressure, respiratory disorders  and heart problems. When used in dietary supplements, it supposedly promotes fat loss and helps you lose weight. 
Forskolin is one of the more common ingredients in dietary supplements. It’s available through various retailers and local health stores. We like that the herb is natural and is found in products promoting weight-loss, but read on…
Conflicting Reviews – “A Problem?”
Our first issue with are the conflicting reviews of forskolin. “There’s information available promoting the cardiovascular effects  of this extract,” said our Research Editor. “Unfortunately, benefits and effectiveness are mixed.”
According to one customer, “I have taken Forskolin for three months (3 bottles) and have not lost an ounce.” 
“This stuff does not work. I have used this religiously for a month with a modified food plan and got nothing. I feel it’s not worth the money,” said another user.
After looking around a bit longer, we did find a few supportive comments. One said, “I noticed a little bit more energy.”
Another claimed, “It has been working well. It has decreased my appetite.” 
No Real Results from Forskolin – “Concerning?”
The lack of real scientific data regarding forskolin supplements should not be overlooked. Just take a look at what this dieter said, “After 1 week of using product, I gained 2 lbs and then found that in a separate study also published in 2005 and available free online that investigated the effects of forskolin on 23 female subjects, the researchers found that their results suggest that forskolin does not appear to promote weight-loss― but in fact, actually promotes weight gain in overweight females.” 
Another user commented, “Couldn’t tell it did anything for me.”
Results are different from one person to the next. One user that saw little changes said, “I’ve been using this product for just under four weeks, and I think my stomach may be getting flatter.”
Another spoke about appetite, “This is not a wonder pill for weight loss but I have noticed my hunger is diminished.”
Our extensive research has revealed if there is a certain part of a weight-loss formula or diet program that is quite bothersome (fad ingredients, lack of real clinical studies, a difficult exercise) the odds of prolonged fat loss are not good. Therefore if forskolin supplements do fail to yield real results in numerous dieters, this could be a serious dilemma.
The Science – “Legit?”
There is some clinical research that has been done with forskolin. However, these studies have shown that it may help with heart conditions and asthma.  On the other hand, there is no science linking this plant ingredient to fat loss or weight reduction. Here at DietSpotlight, we prefer to see documentation that associates the product with weight-loss or we cannot get behind the supplement.
The Bottom Line – Does Forskolin Work?
Should we rev up the engines to buy this one? We are glad to see that forskolin may help with heart problems and asthma  and that it’s not associated with negative side effects.  Even though these supplements are very easy to come by online, the fact that this one doesn’t necessarily promote weight-loss is a concern we can’t overlook.
Those who need to see faster results and slim down now, we advise you to choose a diet supplement that uses clinically proven ingredients and is backed by plenty of positive user reviews.
Among the best products we’ve seen this year is one called Leptigen. This supplement offers a unique blend of four key ingredients, which are proven in published scientific research to help speed up fat loss and kick-start metabolism. Also, we have not located any complaints regarding side effects and customer comments found online indicate people are seeing excellent results.
Also, the business behind Leptigen is so confident in the formula that they’re offering a Special Trial Offer, which is a good sign.
Previous Forskolin Review (Updated May 7, 2014):
What You Should Know about ForskolinColeus Forskohlii is a plant used in alternative medicine for centuries. The plant is commonly used to support heart and respiratory health. Recently, coleus forskohlii has been associated with weight loss supplements and diet pills. This is a popular option for diet supplements from yesterday to tomorrow, like with Slimirex and Tarturus. The chemical forskolin is at the heart of coleus forskohlii, but the popularity of forskolin may be ill-advised. Formulations of forskolin that require oral intake, as is the case with most diet products, are not proven effective. Effective delivery typically involves the chemical being introduced intravenously or through inhalation.
List of IngredientsChemical found in the roots of the coleus forskohlii plant.
Product Features off ForskolinThe plant itself vaguely resembles the leaf pattern of Caralluma Fimbriata. When properly given, forskolin will widen vessels of the heart and increase the strength at which the heart beats. This causes a drop in blood pressure, which is ideal for dieters and bodybuilders taking fat burners with stimulants. Stimulants tend to increase blood pressure thus forskolin could decrease that effect, if it worked orally. Clinical studies have not found any reason to believe that forskolin is effective when taken in oral form. Diet pill manufacturers will often list the proven effects of an ingredient in the product description. For instance, a fat burner with a strong stimulant may list forskolin as an ingredient to lower blood pressure and reduce the risk of negative side effects. However, this is not completely true. Yes, forskolin has this effect, but when the dieter takes it via a diet pill, it does not work that way in the body. Similarly Glucomannan, being a stool increasing ingredient, may have other listed functions. Call it stretching the truth. We took a virtual stroll through a major online vitamin portal looking for forskolin and we found several brands available from major supplement manufacturers. The description of forskolin as a whole listed body transformation as one of the main benefits, but this is another stretch of the truth. We found no evidence that forskolin in oral form has any effect on the body. We were unsettled by the possible Forskolin Side Effects.
Advantages of Forskolin
- Forskolin is available from major, trusted vitamin companies.
- The supplement is available as a standalone product or as part of a diet pill.
- May lower blood pressure when delivered by a proven method.
Disadvantages of Forskolin
- Not proven to work when taken by mouth.
- Not likely to increase weight loss or decrease blood pressure in pill form.
ConclusionForskolin is just another casualty of the weight loss market like that Forskolin found in Naturewise. The facts listed for forskolin on so many websites are mostly true, but the delivery system is what determines whether or not the supplement will work as claimed. Dieters cannot take oral forskolin and expect it to work, because digestion renders the supplement useless. Intravenous forskolin is only available in a hospital setting. Dieters should not look for forskolin to make a huge difference in weight loss.

Forskolin Scientific Abstracts:
Forskolin (Coleus Forskohlii)
The coleus forskohlii extract displayed significant activities on weight-loss and was found to be safe and extremely effective in decreasing body fat in overweight subjects. There need to be higher quality trials to determine the exact uses and efficacy of coleus forskohlii extract in personal supplements and pharmacological intervention. 
There were no substantial distinctions observed in macronutrient or caloric consumption. Coleus forskohlii showed a proclivity to mitigate gains within body mass (-0.7 ± 1.8, 1.0 ± 2.5 kg, p = 0.10) as well as scanned mass (-0.2 ± 1.3, 1.7 ± 2.9 kg, p = 0.08). There were no differences observed in fat mass (-0.2 ± 0.7, 1.1 ± 2.3 kg, p = 0.16), body fat (-0.2 ± 1.0, 0.4 ± 1.4%, p = 0.40), or fat free mass (-0.1 ± 1.3, 0.6 ± 1.2 kg, p = 0.21). Participants in the coleus forskohlii group showed a tendency to display less fatigue (p = 0.07), fullness (p = 0.04) and hunger (p = 0.02). There were no clinically important interactions noticed in metabolic markers, muscle and liver enzymes, blood lipids, red cells, hormones, white cells, heart rate, reports of side effects, electrolytes, or blood pressure. In conclusion, it was indicated that coleus forskohlii does not seem to trigger weight-loss. However, it could assist in mitigating weight gain in overweight individuals with no substantial side effects. 
Forskolin is a diterpene taken from coleus forskoli, which is a powerful cAMP stimulator. This study observed the effects of forskolin metabolism, blood flow, and platelet aggregation. It was discovered that forskolin contained a vaso-relaxing property (dose-dependent) on sheep models in vivo. Also, forskolin decreased whole blood platelet aggregation (dose-dependently) as well as the release of ATP. Pretreatment of PTFE grafts along with forskolin substantially reduced platelet intake 3 hours before and on the first postoperative day. Microcalorimetric techniques measured overall metabolism following treatment with forskolin ex vivo and in-vitro and were significantly elevated postoperatively. Forskolin had direct effects on blood flow and platelet parameters favoring the setting of occlusive arterial disease and reconstructive arterial surgery. 
Forskolin triggered an expected stimulation of cAMP production in testicular Leydig cells. Forskolin, when given in concentrations of 1-10 microM, also potentiated gonadotropin-induced responses. Additionally, Forskolin triggered an elevation in sensitivity to hormonal stimulation in every cAMP pool when given at lower doses which had no effect on cAMP generation and testosterone response (100 nM). It also showed a 70% decrease in the ED50 for stimulation of human chorionic gonadotropin testosterone production.

Forskolin Side Effects:
In the universe of weight-loss products, the words “natural” and “herbal” are often thought to also mean safe. However, every formula has equal potential for issues. Although Forskolin side effects do not apply to all its consumers, that doesn’t mean some don’t experience them.
Low Blood Pressure
Low blood pressure occurs when the forces of blood pushing within the vessels are lower than usual. This usually isn’t considered an issue as this can be indicative of good health. However, some issues that can be accompanied with this symptom include dizziness, nausea, fainting, a lack of concentration, blurred vision, and fatigue.
What causes low blood pressure?
Some of the common causes of low blood pressure may include bed rest, decreased blood volume, medications, allergic reactions, nutritional deficiencies, or some issues with other organs, like the heart or thyroid.  If the levels get too low, then it is important to seek medical attention immediately.
Throat irritation is a blanket term for a number of different symptoms, which may include dry coughing, an itchy throat, or having a strange sensation of bumpiness or stickiness in the area. It can also be indicative of various other health concerns.
What causes throat irritation?
Throat irritation are a very common symptom for various issues, like allergies, infections from viruses and bacteria, environmental factors, acid reflux, and some eating disorders like bulimia. Usually, it does not need medical attention because it can be resolved on its own.
According to the Mayo Clinic, “A cough is your body’s way of responding when something irritates your throat or airways.”  Occasional coughing is completely normal and should not be thought of as an issue, but if it is severe and continuous, medical attention may be necessary.
What causes coughing?
Common causes of coughing can include the cold, influenza, environmental irritations, and others. There can be many more severe health problems that can warrant this symptom, like asthma, lung cancer, or even heart failure.
Restlessness if more commonly known as agitation. Although it is normal to experience this, as a symptom, it can be quite a nuisance on daily life.
What causes restlessness?
Restlessness is not often caused by medication, but instead stress, mental illness, hormonal imbalances, and environmental factors involving peer pressure and feeling ill. Forskolin side effects are not guaranteed, but there have been some issues with low blood pressure, coughing, throat irritation, and restlessness. To protect yourself from potential problems, it is always the best idea to consult with your physician before taking any supplement, especially if you’re taking prescription medications, are under 18, have a medical condition of any kind or are pregnant or nursing.
Forskolin, also known as coleus forskohlii, is a plant extract. It's been used for thousands of years to treat a long list of medical conditions. There is some science linking it to asthma relief and cardiomypopathy, but not weight-loss or increased performance.

Forskolin is a chemical found in the flower Plectranthus barbatus. This plant has been used for centuries in alternative medicine to treat heart disorders, but recently it has gained popularity due to the mention of its weight-loss potential on Dr. Oz’s show. In 2014, Dr. Oz described the compound as “lightening in a bottle” and “a miracle flower”.
What is it Supposed to Do?
Forskolin has a lot of uses in alternative and modern medicine. When taken orally, it is used to treat a variety of things, including allergies, skin conditions, urinary tract infections, and more. Doctors sometimes use this chemical in IVs to help treat heart failure. When used as drops, forskolin may treat the eyes for glaucoma. Forskolin is clinically tested and shown to help lower blood pressure. It does this by producing a powerful heartbeat and widening the blood vessels.
In a study published in Obesity Research, forskolin was found to provide results in decreasing body fat percentage and fat mass. In the conclusion, the study reports, “The results indicate that forskolin is a possible therapeutic agent for the management and treatment of obesity.”
Another clinical trial did not have the same results. In a study published in the Journal of the International Society of Sports Nutrition, they reported, “Results suggest that CF [forskolin] does not appear to promote weight-loss but may help mitigate weight gain in overweight females with apparently no clinically significant side effects.”
