What You'll Learn

Lack of evidence for weight loss
Forskolin is a weight loss supplement derived from the root of a plant called Coleus forskohlii, a member of the mint family. It has long been used in folk medicine for asthma treatment and various other ailments, but is now marketed as a weight loss supplement.
While forskolin may raise fat-burning capabilities, this is irrelevant without a nutritious diet and exercise to support a calorie deficit. In other words, a person must burn more calories than they consume through food and drink. If this does not happen, a person will not lose weight.
There is a lack of substantial evidence to support the use of forskolin for weight loss or any other health condition. Some studies suggest that forskolin may aid in weight loss and muscle building, but more research is needed to confirm these results and establish its safety. Optimal doses for forskolin have not been established, and it is not known whether taking forskolin is safe. Some negative reactions have been reported, including flushing, fast heartbeats, low blood pressure, upper respiratory tract irritation, cough, tremor, and restlessness.
People taking blood thinners or antiplatelet drugs should not take forskolin, and it should be avoided by those with polycystic kidney disease. The safety of forskolin in pregnant and breastfeeding women is also unknown, so it should be avoided by this group.
It is important to be cautious with any supplement or herb, as they are not monitored by the FDA and could have issues with purity, quality, or dosage. Weight loss supplement manufacturers can sometimes hide other potentially dangerous ingredients in their products.

Potential health risks
While forskolin is generally recognised as safe and well tolerated, there are some potential health risks to be aware of. Firstly, optimal doses for forskolin have not been established, and the quality of active ingredients and levels of concentration can vary between different makers of the supplement. As such, it is recommended that forskolin only be taken under the supervision of a healthcare professional.
Secondly, although forskolin is not known to interact with any existing conditions, those taking blood thinners, antiplatelet drugs, or medication for low blood pressure should avoid forskolin. Additionally, certain high blood pressure drugs may interact negatively with forskolin, so it is important to consult a doctor before taking forskolin or any dietary supplement. Furthermore, forskolin should be avoided by those with polycystic kidney disease, and its safety in pregnant and breastfeeding women is unknown, so it is recommended that they also avoid it.
Some negative reactions to forskolin have been reported, including flushing, fast heartbeats, low blood pressure when taken through an IV, upper respiratory tract irritation, cough, tremor, restlessness when inhaled, and stinging of the eyes. It is important to note that forskolin may also cause gastrointestinal side effects such as diarrhoea, as it increases the production of acid in the stomach.
Moreover, weight loss supplement manufacturers may include other potentially dangerous ingredients in their products, and the U.S. Food and Drug Administration (FDA) has cautioned consumers against many weight loss supplements on the market. In Europe, there have been reports of acute poisoning following consumption of products containing forskolin, possibly due to contamination. Therefore, it is crucial to exercise caution when taking any supplement or herb, as they are not monitored by the FDA and may have issues with purity, quality, or dosage.

Drug interactions
While forskolin is a popular weight loss supplement, it is important to note that it is not a miracle drug, and there is no substitute for a nutritious diet and exercise for weight loss. Quality clinical trials are lacking to support the weight loss properties of forskolin, and it is not known whether taking forskolin is safe as it has not been thoroughly studied.
Regarding drug interactions, people taking blood thinners or antiplatelet drugs should not take forskolin. Additionally, certain high blood pressure drugs may interact with forskolin. For example, forskolin should be avoided with phenylpropanolamine as it may increase the risk of cardiovascular side effects such as an increased heart rate. It may also increase the effects of moxonidine, nadolol, and nebivolol through pharmacodynamic synergism.
Furthermore, forskolin should be used with caution alongside anticoagulants. It increases anticoagulation when taken with alteplase, American ginseng, aspirin/citric acid/sodium bicarbonate, and nabumetone. On the other hand, it decreases anticoagulation when taken with mistletoe, nettle, and vitamin K1 (phytonadione). The effects of these interactions are not entirely clear, so caution and monitoring are advised.
Pregnant and breastfeeding women should avoid forskolin due to a lack of safety information. Additionally, forskolin should be avoided by individuals with polycystic kidney disease. Before taking forskolin or any dietary supplement, it is important to talk to your doctor about potential risks and interactions with other medications.

Contamination issues
Forskolin is a plant-based product derived from the root of a plant in the mint family, Coleus forskohlii, which grows in Nepal, India, and Thailand. It has been used in traditional Ayurvedic medicine and as a folk remedy for asthma. Today, it is most commonly used as a weight loss supplement.
Weight loss supplement manufacturers have been known to hide other potentially dangerous ingredients in their supplements. This has led the U.S. Food and Drug Administration (FDA) to caution consumers against many weight loss supplements on the market. In Europe, there have been reports of acute poisoning following the consumption of products containing forskolin, possibly due to contamination.
Because supplements and herbs are not monitored by the FDA, issues with purity, quality, or dosage may arise. The quality of active ingredients and the level of concentration in products containing forskolin can vary from maker to maker. Some experts recommend that forskolin only be taken under the supervision of a healthcare professional.
It is important to be cautious with any supplement or herb, as they may pose risks for certain groups. For example, people taking blood thinners or antiplatelet drugs should not take forskolin. Additionally, certain high blood pressure drugs may negatively interact with forskolin. The safety of forskolin in pregnant and breastfeeding women is also unknown, so it should be avoided by this group.

Benefits for asthma
While forskolin is primarily marketed as a weight loss supplement, it has been used as a folk remedy for asthma for centuries.
Forskolin is derived from the root of a plant called Coleus forskohlii, which is a member of the mint family. It is native to Thailand, Nepal, and India, where it has been used in traditional Ayurvedic medicine.
Similar Mechanism to Conventional Asthma Drugs
Forskolin appears to work in a similar way to certain types of conventional asthma medications. It boosts the levels of a compound called cyclic AMP, which helps to relax the muscles around the bronchial tubes, making breathing easier.
Safe Alternative to Beta Blockers
In the context of asthma, forskolin has been found to be a safe alternative to beta-blockers for glaucoma patients. Beta-blockers are known to worsen asthma symptoms, so forskolin may be a preferable option for these patients.
Reduction in Upper Respiratory Tract Irritation
While not directly related to asthma, forskolin has been shown to cause upper respiratory tract irritation when inhaled. This suggests that it may have a direct effect on the respiratory system, which could be beneficial for asthma symptoms when taken orally.
Historical Use in Folk Medicine
As mentioned, forskolin has a long history of use in folk medicine for the treatment of asthma. This traditional knowledge and historical use provide some support for the potential benefits of forskolin in asthma management.
It is important to note that while forskolin shows potential for asthma treatment, the existing research is limited. More human studies are needed to establish the effectiveness and safety of forskolin for asthma specifically. As with any supplement, it is recommended to consult a healthcare professional before taking forskolin, especially if you have existing medical conditions or are taking medication.
