Coleus Forskolin Root Extract

Also known as: Coleus forskohlii, Forskolin, Coleus

Overview

Coleus forskohlii is a plant native to India and Southeast Asia, primarily recognized for its forskolin content. Forskolin, a labdane diterpenoid, is extracted from the plant's roots and has been traditionally used in medicine. As a supplement, it is marketed for weight loss, metabolic health, and cardiovascular benefits. Forskolin is believed to work by activating adenylate cyclase, increasing cyclic AMP levels, which influences various physiological processes. While research shows some promise, particularly in weight management and improving certain metabolic markers, the evidence is considered moderate, and more rigorous trials are needed to confirm its efficacy and safety. It is available in various forms, including capsules and tablets, and is often standardized to contain a specific percentage of forskolin.

Benefits

Forskolin has been studied for its potential benefits in weight loss and metabolic health. Some studies suggest it may aid in weight loss and reduce body fat percentage, with a systematic review indicating an average weight loss of 1.1 kg more than placebo. It may also improve insulin sensitivity and increase HDL cholesterol levels. These benefits are primarily observed in overweight or obese individuals. However, the effect sizes are generally modest, and more research is needed to confirm these findings. Benefits are typically observed after several weeks of consistent supplementation. The quality of evidence varies, with some studies showing promising results but limited by small sample sizes and methodological limitations.

How it works

Forskolin primarily works by activating the enzyme adenylate cyclase, which increases intracellular levels of cyclic AMP (cAMP). Elevated cAMP levels can influence various physiological processes, including the activation of protein kinase A (PKA). PKA is involved in regulating glycogen, sugar, and lipid metabolism. This activation can lead to increased fat breakdown (lipolysis) and thermogenesis. Forskolin's effects extend to the cardiovascular system, potentially causing vasodilation. It also interacts with the metabolic system by influencing insulin sensitivity. The absorption and bioavailability of forskolin are not well-documented, but it is known to be absorbed orally.

Side effects

Coleus forskohlii is generally considered safe when used appropriately, but it can cause side effects in some individuals. Common side effects include gastrointestinal issues such as nausea and diarrhea. Less common side effects may include headaches and dizziness. Rare side effects such as allergic reactions have been reported. Forskolin may interact with blood thinners and diabetes medications, potentially increasing the risk of bleeding or affecting blood sugar control. It is contraindicated in pregnancy, breastfeeding, and individuals with certain cardiovascular conditions. Caution is advised for individuals with bleeding disorders or those taking anticoagulants. It's crucial to consult with a healthcare provider before starting forskolin supplementation, especially if you have underlying health conditions or are taking other medications.

Dosage

The typical recommended dosage of Coleus forskohlii extract is between 250-500 mg per day, standardized to contain 10% forskolin. A minimum effective dose is often considered to be 250 mg of a 10% forskolin extract per day. It is best taken with meals to minimize gastrointestinal side effects. While a maximum safe dose is not well-established, higher doses may increase the risk of side effects. Capsules or tablets are the most common forms of supplementation. Food may enhance absorption. It is essential to adhere to recommended dosages and consult with a healthcare provider before starting supplementation.
