Ingredient explainerWhat Is A Normal Forskolin Dosage, And How Much Is In RetraBurn?
Quick answer. This website gives no recommended dose. The best-known trial gave overweight men 250 mg of a 10% forskolin extract twice a day, so 500 mg of extract daily, for twelve weeks. RetraBurn does not publish an amount for forskolin. The whole 21-ingredient blend weighs 15.47 mg.

The 15.47 mg figure is printed on the panel, and the gaps are named in plain words.

- The Godard 2005 trial used 250 mg of a 10% forskolin extract twice daily, so 500 mg of extract a day, for 12 weeks.
- A 2026 twelve-week Coleus forskohlii trial repeated the design with a branded extract.
- RetraBurn lists Forskohlii (Coleus forskohlii) root extract ninth of 21, marked 20:1 concentrate.
- The amount of forskolin in RetraBurn is not published. The whole blend weighs 15.47 mg.
- A 20:1 mark and a 10% forskolin figure are different measures and cannot be converted into each other.
- No trial of the finished RetraBurn formula exists. This page is not dosing advice.
What dose did the forskolin trials use?
The most-quoted trial in the category is Godard 2005. It gave overweight men 250 mg of a 10% forskolin extract twice a day for twelve weeks. That is 500 mg of extract a day. A 10% extract means the forskolin itself is about a tenth of the extract, which works out to about 50 mg of forskolin a day. That figure is plain arithmetic on the trial wording, not a number the abstract states.
A 2026 trial ran for twelve weeks too and repeated the design with a branded extract. Both are real trials, at real amounts.
Notice what the numbers describe. They describe the extract, the strength of the extract, the frequency and the length of time. A dose is all of those together, and it belongs to that trial.
What does the RetraBurn label say about forskolin?
It lists the ingredient and nothing else. The entry reads Forskohlii (Coleus forskohlii) Root Extract, in ninth place on the blend list, carrying a 20:1 concentrate mark.
The amount is not published. Forskolin shares the one declared weight of 15.47 mg with 20 other entries. No percentage of forskolin is printed either. So the label cannot tell you how much forskolin is in a dropperful, and this page will not guess.
What the blend total does establish is a ceiling: no single member can weigh more than 15.47 mg. That is true of forskolin root extract and of every other entry.
How big is the gap between the trial and the label?
| Measure | Amount |
|---|---|
| Trial extract a day | 500 mg (250 mg twice) |
| Trial forskolin a day, at 10% | about 50 mg |
| Whole RetraBurn blend a serving | 15.47 mg, shared by 21 entries |
Arithmetic on the figures above. The label does not say how much of the 15.47 mg is forskolin root extract.
Set 500 mg of extract beside 15.47 mg for the whole blend. The trial amount is more than 32 times the entire blend, before any share is taken by the other 20 ingredients. Even if forskolin root extract were all of the blend, which cannot be true, it would be far under the trial amount.
That does not make the ingredient bad. It means the trial is a study of a different amount. Cochrane's chromium review has the same shape: its smallest pooled dose was well above the 7 mcg on this bottle.
Does the 20:1 mark tell you the dose?
No. A 20:1 mark means the extract was concentrated from twenty times its weight in raw plant. It describes the starting material, not what went into the bottle.
A "10% forskolin" figure describes something else: how much of the extract is the compound forskolin. These are two different measures. One cannot be turned into the other. This is why you cannot multiply the 20:1 mark by the blend total and recover a dose. Anyone who offers you a neat forskolin number for RetraBurn has invented it.
What do the forskolin trials not tell you?
Quite a lot, and it is worth saying plainly.
They do not tell you what a 15.47 mg blend does. They did not use this formula, this amount or this mix of 21 ingredients.
They do not tell you what happens beyond twelve weeks. The longest period named for forskolin on this website is twelve weeks.
They do not tell you how forskolin behaves next to your medicines. No interaction data is published in the sources.
They do not turn into dosing advice because a number is printed. A trial dose is a record of what happened in that study. It is not a recommendation for you.
Read the trial as a way to see how far a label sits from the research. That is its use here.
Is there a safe or normal forskolin dose for you?
This website cannot say, and it does not publish a recommended dose. The trials are not dosing advice. They show what researchers gave to the people in their study.
If you are tempted to add a separate forskolin product on top of RetraBurn, stop and ask a doctor first. RetraBurn's caution is "Do not exceed recommended dose", and stacking products that share ingredients is one way people do that without noticing. The sources do not publish any interaction data for forskolin, so the question belongs to a clinician who knows your medicines.
For the general version see can I use RetraBurn with other supplements.
What should you do with this information?
- Do not compare a trial amount to a label as if they were the same. Check what each measures.
- Do not buy RetraBurn expecting a forskolin dose. None is published.
- If forskolin is the reason you are reading, ask yourself whether a blend of 21 is the right shape of product for that goal. A single-ingredient product with a printed amount lets you do the check.
- If you buy RetraBurn, buy it for what it is: a daily liquid with a printed ceiling and a 60-day window from purchase.
The ingredient list, with each entry's research, is on what are the RetraBurn ingredients.

Our view
Our view is that the honest answer to the question is two numbers and a shrug. The trial used 500 mg of extract a day. The label does not say what its forskolin weighs. Between them sits a blend total of 15.47 mg.
That does not condemn the bottle. It tells you that the trial and the product are different things. If a seller offers you a clean forskolin dose for a 21-ingredient blend, ask where it came from.
