Coleus Extract
An Ayurvedic herb standardized for Forskolin, primarily used for weight management.
Also known as: Coleus forskohlii • Forskolin
Overview
Coleus forskohlii is an herb from the mint family, traditionally used in Ayurvedic medicine. Its primary active compound, Forskolin, is believed to aid in weight loss by increasing levels of a molecule called cyclic AMP (cAMP), which may stimulate fat burning.
Key Benefits
May Aid in Weight Management
Forskolin increases cAMP levels, which can lead to an increase in fat breakdown (lipolysis) and may help reduce body fat.
Improves Body Composition
Some studies suggest that Coleus extract can help increase lean body mass while decreasing fat mass, leading to a more favorable body composition.
Supports Cardiovascular Health
Forskolin has been studied for its potential to lower blood pressure and improve heart function, though more research is needed.
Dosage & How to Take
The effective dose of Coleus extract depends on the standardization of Forskolin. Most studies use 250 mg of an extract standardized to 10% Forskolin, taken twice daily.
| Purpose | Dose | Notes |
|---|---|---|
| Weight Management | 500 mg/day (10% extract) | Split into two 250 mg doses. |
| Asthma (Investigational) | 10 mg/day (pure forskolin) | Used in clinical research, not a standard supplement dose. |
| Glaucoma (Investigational) | Topical application | Eye drops containing forskolin have been studied. |
Best Time to Take
Best taken 20-30 minutes before meals to potentially aid in fat metabolism.
With or Without Food
Can be taken with or without food, but taking it before meals is common for weight management purposes.
Forms & Bioavailability
| Form | Absorption | Best For | Notes |
|---|---|---|---|
| Standardized Extract Capsules | High | Accurate dosing of Forskolin | Look for extracts standardized to 10% or 20% Forskolin. |
| Root Powder | Low | Traditional use | Forskolin content is variable and not guaranteed. |

Scientific Research
Body composition and hormonal adaptations associated with forskolin consumption in overweight and obese men
A 12-week study found that 250 mg of a 10% forskolin extract twice a day favorably altered body composition, decreasing body fat percentage and increasing lean mass.

This study showed a trend towards mitigating weight gain in overweight women, but did not significantly affect body fat.
