Forskolin Fuel

Forskolin Fuel has sparked media and public interest over the past few years because of claims of its significant effects upon weight loss and metabolism function. Another unusual property of Forskolin Fuel is that it only contains one active ingredient which allegedly burns fat rapidly and effectively.

Forskolin Fuel Pros
  • The company claims that they only use 100% pure Coleus extract in their product which has been clinically researched to ensure maximum effectiveness
  • The manufacturer offers all customers a money back guarantee if they are not fully satisfied with the product
  • Forskolin Fuel has appeared on television in the US which somewhat reinforces the company’s claims about how it works to burn fat and shed pounds
  • The product website provides information about a clinical study which tested the effectiveness of Forskolin Fuel
Forskolin Fuel Cons
  • The company’s returns policy is very specific. The returned product needs to be unopened, unused and returned within 90 days of purchase so a customer cannot try the product and then return it if unsatisfied with the effects
  • The product website does not give a full list of ingredients. The ingredients can only be seen on the product label when purchased. However, Amazon does provide an image of the label on the Forskolin Fuel page but the information is small and unclear
  • The given clinical study may have been chosen specifically to support the product. Other clinical studies with inconclusive results may have been discarded in favour of positive ones
  • The product website includes no customer feedback or reviews about Forskolin Fuel

Forskolin Fuel Review

Forskolin Fuel is manufactured in the United States but can be bought online from many countries around the world, including the United Kingdom. It seems to be aimed specifically at women after looking at the images and testimonials on the product website. However, there is no information which excludes men from using the product. This website also has information about how the product works and the one active ingredient which claims to be the force behind Forskolin Fuel’s alleged effectiveness. Lots of this given information is limited and often instructs the customer to look at label information on the product after they have made an order.

Forskolin Fuel Claimed weight loss benefits

Forskolin Fuel claims to have three key outcomes to provide a customer with the tools to lose weight successfully. These outcomes are: promoting healthy weight management, increasing the rate of metabolism, and optimising hormone levels within the body. The final point in this list may not be associated with weight loss but still claims to maintain the body in good health and ensure hormone production is balanced and fully operational.

How Forskolin Fuel Works

Forskolin Fuel claims to work by increasing metabolic rate and hormones that are thought to maintain and have an effect on weight loss. The product website has a tab labelled ‘How It Works’ which has some information about how the product acts upon the body, but this information is somewhat limited and does not refer to any authoritative sources. However, other information about the Coleus Forskohlii extract (the only stated ingredient of the supplement) is available online when entered into search engines. Forskolin Fuel only has one active ingredient which means there is little risk of interaction between ingredients that may affect the way they work to aid in weight loss.

Coleus Forskohlii Extract

Forskolin Fuel contains only one active ingredient which claims to aid in weight loss. The company states that they use an optimised level of the extract (20%) to achieve maximum weight loss effects for their customers. The scientific properties of this ingredient is given on the ‘Ingredients’ tab of the product website which provides the chemical properties of the compound, Forskolin.

Coleus Forskohlii allegedly works by ‘activating the enzyme, adenylate cyclase’; this enzyme (found in thyroid membranes) activates lipoproteins which break down fats that enters the body. These fats are therefore used for fuelling the functions of the body instead of simply storing it in pockets and causing weight gain. Overall, Coleus Forskohlii claims to act as a regulatory ingredient which directly targets the metabolic system and boosts the rate of weight loss. However, it is probably best to use this ingredient alongside regular exercise and a healthy diet to achieve maximum effects.

More details about how the ingredient forskolin works are given on WebMD, a more authoritative source than the product website. This site does state that quality clinical trials are lacking so don’t fully support the ingredient as a weight loss product. However, this site does explain how forskolin helps treat heart conditions by widening the blood vessels within the body and affecting the cardiovascular system. There are no details about how forskolin works to increase weight loss but the fact that the ingredient widens blood vessels and increases heart rate could suggest that the ingredient has some effect on the metabolic system, potentially working as a weight loss aid.

Forskolin is the main element within the Coleus Forskohlii extract. The research for Forskolin is still very limited, yet many sources claim that the studies already undertaken have promising results which support forskolin as a potential weight loss assistant. More information about clinical studies and trials is explained in the below ‘clinical studies’ section of this review.

Key Ingredients

The Forskolin Fuel supplement has very few ingredients and the only one is given on the product website is Coleus Forskohlii, or forskolin. However, the product label is available online from the Amazon product page and gives the full list of ingredients. The label states that Maltodextrin, Gelatin and Magnesium Stearate are included in the supplement but are not ingredients with any weight loss effects; they are only included as anti-adherents or as lubricants. After reading the product label it is clear that the product website is correct by stating that Coleus Forskohlii is the only ingredient with possible weight loss potential and supports statements put forward by the company.

Coleus Forskohlii Extract

Plectranthus Barbatus (also known as Coleus Forskohlii) is a perennial plant grown in the tropics in various locations around the world, particularly in South America. The plant has sparked media and public interest because it produces the chemical forskolin, which is the sole weight loss ingredient of Forskolin Fuel. However, the plant’s roots have also been used for medicinal purposes and are thought to strengthen the muscles around the heart and are useful for issues such as heart disease. This said, the anti-obesity effects of Coleus Forskohlii is what has spurred the interest of the media, the public and dietary supplement companies.

Clinical Studies

Clinical Researcher 538
Some ingredients used in dietary supplements have been researched in clinical studies to measure their potential results, possible dangers and general function as a successful supplement ingredient. The main ingredient of Forskolin Fuel, Coleus Forskohlii, has had several clinical studies undertaken to evaluate its potential effects when included in the supplement. However, the product itself has not been tested thoroughly as a whole, only individual ingredients have been researched to support their effectiveness. A lack of research can damage a supplement’s reputation, yet multiple studies can help support the positive aspects of a product.

Coleus Forskohlii Extract

A study from 2005 tested Coleus Forskohlii (CF) on 23 mildly overweight female subjects. The women took the supplement or a placebo alternative for 12 weeks, twice daily, and the results were measured in terms of weight. However, the results of this study showed that the CF extract had no significant influence on the weight of the subjects. One interesting point to consider is that this study tested a 10% CF extract whereas Forskolin Fuel uses an optimised 20% level of toxicity; therefore, the failed result may be due to the lower concentration of Coleus Forskohlii. The study did, however, report that CF had no reported side effects on any of the 23 female subjects so could be deemed safe to use in regular amounts as a dietary supplement.

The product website does in fact reference another clinical study which was undertaken and published in ‘Obesity Research’ in 2005. This trial took 30 overweight or obese men and gave them either forskolin or a placebo pill daily for 12 weeks. During this trial the forskolin was at the optimised 20% concetration unlike the previous study detailed above. After the 12 week period, the men had on average lost more weight and gained more lean body mass than those who had taken the placebo pill. However, one thing to consider with this study is that it has been handpicked by Forskolin Fuel to promote their product. Therefore, it may be that other studies with inconclusive or negative results have been purposefully excluded to maintain the company’s reputation.

A further external study was completed in 2005 which tested the antiobesity effects of forskolin on female Wister rats. This animal trial showed positive results of a significant weight decrease in the rats which were fed a controlled diet. Although the results only stated that the CF extract ‘may be useful in the treatment of antiobesity’ there were no reports of the ingredient being ineffective on weight loss. The report for this study is very limited in terms of detail but does provide readers with the basic information and results from the research trial.

A more recent study was undertaken in 2014 and its method and results were very similar to the above trial on Wister rats from 2005. This study focused on the metabolic benefits of Coleus Forskohlii and its potential as an anitobesity supplement. The report for this study is more in depth than the previous 2005 animal-based trial; each step and objective is outlined in moderate detail. Five groups of Wister rats, six animals in each group, were each given various diets and supplements (including Coleus Forskohlii) and their weight and food intake was measured before and after the study. The results showed that the Coleus Forskohlii ‘significantly halted increase in food intake and weight gain’ within the subjects and could potentially act to ‘curb appetite’.

This variation in results could raise speculation over the success of the supplement. However, the negative results may be scientific anomalies caused by certain controlled factors of the experiments. The Forskolin Fuel company may have handpicked the best results from clinical studies to promote their product. Therefore, this mix of results do not fully support Forskolin Fuel as an effective weight loss aid, yet the positive results do not discount it entirely.

Weight Loss Power: 50/100

The majority of clinical studies conclude that the primary active ingredient of Forskolin Fuel, Coleus Forskohlii, has some effect on weight loss to varying degrees. Customer feedback on retailer sites such as Amazon are extremely varied in terms of their experiences with the product, some claiming that it had little effect and others that it is a successful weight loss aid when taken according to the directions on the product label.
Speed of results: 50/100

The lack of available information about the speed of results is the reason behind this mid-point score. Some customers claim that after using the product after a week, they already saw results, yet others do not share such positive experiences. The product website has no information about when customers should start seeing results.
Appetite Suppression: 10/100

The 2014 study seems to conclude that some form of appetite suppression may occur after using the Coleus Forskohlii extract but this is not supported by any other authoritative source or research. The Forskolin Fuel company also does not refer to any appetite suppression effects caused by their product.
Long Term Results: 30/100

The product claims to act as an effective weight loss aid but the company does not offer any guidance as to how long the effects, if achieved, will last and no customer feedback contains details of this factor. However, the product label does not include any information about how long it is safe to use the product for. Therefore, with this lack of limitation it seems possible for a customer to use the supplement for as long as they require, although it is probably sensible to limit usage with breaks in between courses.
Safety: 75/100

Some clinical studies state that the primary ingredient in Forskolin Fuel is possibly safe for moderate use and no significant side effects have been reported to have occurred within users of the product or main ingredient. However, it is always key to consult a physician before taking the product if you are pregnant, nursing, or have any form of medical condition. This information is also stated on the product label.
Value for money: 55/100

The price of the product seems reasonable for the potential effects and quantity of supplements within each bottle – 30 servings which will last one month when taken as directed. Amazon offers a 2 for 1 deal to customers when they buy 3 bottles of Forskolin Fuel at once, for just over £60. However, prices are all around £30 mark from all retailers, including the official product website, which seems reasonable if the product achieves all of the claims made by the company.

Forskolin Fuel Side Effects

Woman With Stomach Ache 538
Forskolin Fuel has a lessened risk of possible side effects because it only contains one active ingredient. However, because this ingredient is extracted from natural plant sources, it does not mean that it comes without any potential side effects. Some studies have been undertaken to measure the possible dangers of Coleus Forskohlii, or forskolin, in order to warn customers about possible side effects or to conclude that these are limited symptoms and the product is safe for use. The product website offers its customers no information about possible side effects but some other online sources give details about possible effects based on scientific research and previous reports of symptoms.

Coleus Forskohlii Extract

Two different online sources give contrasting details of possible side effects. The page for forskolin does not outline any specific symptoms associated with the ingredient but does state that a lack of clinical research results in this void in information. Their website simply states that in terms of potential side effects, there is ‘none well documented’ and therefore users of the ingredient should be wary that some symptoms may occur when forskolin is taken as part of a dietary supplement.

A varying view is outlined on the WebMD site for forskolin, where more specific symptoms are given. However, even this source claims that there ‘is not enough reliable information about the safety of taking coleus [forskohlii]’ and therefore it is primarily claims that are used as evidence to support the safety of Coleus Forskohlii extract. However, when looking in more detail at the WebMD site, the given side effects, including coughing and low blood pressure, are all associated with taking forskolin intravenously or via inhalation. Therefore, this source also gives no information about potential dangers when taken by mouth as part of a dietary supplement.

Other than these referenced sites, clinical studies are the only other source of information concerning the safety of Coleus Forskohlii. As outlined in the previous ‘clinical studies’ section of this review, a study from 2005 had no reports of any side effects in any of its 23 female subjects. This research group was very limited but it does go some way in supporting the ingredient as possibly safe for use. The research report itself claimed that there were ‘apparently no clinically significant side effects’; the term ‘significant’ in this statement is of course a key term which suggests that there may have been some minor effects experienced.

Overall, it seems that the best source of information about potential side effects can be gathered by looking at clinical studies rather than medicinal reference sites such as In terms of Coleus Forskohlii, there is a certain lack of information about the ingredient, yet early research may suggest that it is possibly safe for use when taken as part of a dietary supplement.

How To Use

Woman With Pills 538
The FAQ section of the product website answers the question about recommended dosage with the statement, ‘once you receive the product, you will be able to read the recommended dosage on the product’. After looking at the product label which can be viewed on the Amazon website, the product label shows that the customer should take one capsule once a day. However, there is no information about what time during the day a customer should take the supplement and whether it needs to be taken alongside food or water. This lack of information is one possible downside to the product because it leaves the customer without much guidance after they have received their order. The label also suggests that ‘pregnant or nursing mothers, children under the age of 18, and individuals with a known medical condition should consult a physician before using this or any dietary supplement’. It is always sensible to consult a doctor, if any of the above applies to you, before taking any dietary supplement.

Who Makes Forskolin Fuel

The Forskolin Fuel company only makes one dietary supplement, of the same name, which could result in some customer distrust considering they only have one product on which to make a judgement. The product label states that all supplements are made in the USA, yet UK sales are distributed from a base in Milton Keynes, UK. The product website also gives contact details for 5 major countries and the US telephone number is also for ‘International’ queries. Forskolin Fuel offers a money back guarantee to customers who are not satisfied with their product. However, the packaging needs to be unopened and the supplement unused. This could prove problematic for customers considering they are unable to test the product and return it to the company if they are not happy with the results. Customer reviews seem to be varied, but the majority of unsatisfied customers aimed their feedback at the product’s effectiveness rather than the company’s service and reputation.

Where To Buy

The supplement can be purchased from many retailers online, but the product is not available to buy on the high street in the UK. The Forskolin Fuel company sells the product for the same price as Amazon, when bought singularly, for £30.34. However, the best possible way to buy the product, if a customer wants more than one bottle, is on Amazon where it is possible to purchase three bottles for the price of one at £60.70. The cheapest place to buy Forskolin Fuel is on Ebay, where 1 bottle costs £29.95 and 3 can be bought for £59.90. Overall, the product seems good value for money, under the condition that the product is an effective weight loss aid. All of the above prices work out at around £1 per day, considering each bottle contains 30 servings.

Overall Verdict

Overall, the Forskolin Fuel supplement could prove as effective as media interest suggests, boosting metabolism and increasing weight loss. However, there is a definite lack of clinical research for the product and the primary ingredient, although this research is being developed all the time and early results seem promising and form a good foundation for further studies. The product website provides adequate information for its customers, yet some areas are more vague than others and only refer readers to the product label after they have ordered and received their supplement.

Overall: 45/100
