Forskolin
Coleus forskohlii · 7β-acetoxy-8,13-epoxy-1α,6β,9α-trihydroxylabd-14-en-11-one
The study people still quote is Godard 2005: 250 mg of 10% forskolin twice daily in a small sample of overweight men. Replication is weak. If a label lists Coleus extract without milligrams, the dose-fit is unknowable — which we score as a fail, not a maybe.
- Study-dose band
- 250 mg of 10% forskolin, twice daily (500 mg extract/day)
- Typical bottle
- Often undisclosed; sometimes 100–250 mg of a 10% extract, once daily
Evidence by outcome
| Outcome | Grade | Note |
|---|---|---|
| Body composition | D | Godard 2005 suggested a lean-mass signal in men. Follow-up is sparse and mixed. |
| Testosterone | D | Same small trial. Not a replacement for indicated therapy. |
Safety
- Can lower blood pressure. Avoid stacking casually with antihypertensives.
- GI upset is the usual complaint at extract doses.
Unknowns
- Standardization to 10% forskolin is not the same as 10% of a proprietary blend you cannot see.
Questions
If the box says 10% forskolin, is that a study dose?
Only if the extract weight is in the Godard range — about 500 mg/day of that 10% extract. A percentage without milligrams is marketing.
