Muira Puama Benefits: The Amazon Bark Listed First in Maxforce
Muira puama has a long reputation as a male tonic, but clinical evidence is limited and trials give no suitable dose, according to Drugs.com. In Maxforce it is the first of nine lines in the 82 mg blend, so one gummy holds at least 5 mg of it. The label prints no exact amount, and no study has tested the gummy.

The plant01
What is muira puama?
Muira puama is a small tree from the Amazon, Ptychopetalum olacoides, whose bark and roots have long been used in traditional medicine as a male tonic.
The name is often shortened to "potency wood" in marketing. That nickname tells you about its reputation, not about proof. Drugs.com describes a long reputation as a male sexual stimulant, and says clinical evidence to support effects on sexual dysfunction is limited (Drugs.com, Muira puama).
Maxforce lists it as "Muira Puama Extract". The label gives no plant part and no extract ratio, so the word "extract" says only that it is concentrated. The photo below comes from the brand's image set.
| Name on the label | Muira Puama Extract |
|---|---|
| What it is | Ptychopetalum olacoides, a small Amazon tree |
| Place on the label | 1 of 9 in the 82 mg proprietary blend |
| Amount per gummy | Not printed; at least 5 mg (listed before the 5 mg caffeine line) |
| Amount used in research | No dose established (trials give no suitable dosage) |
| Strength of evidence | Limited; no firm human evidence |
| Marketed or traditional use | Traditional male tonic |
| Main caution | Safety data are limited; no contraindication is listed, which is not the same as none. |
First place02
How much muira puama is in a Maxforce gummy?
At least 5 mg, and probably more. The label lists it first, which means it is the largest share of the 82 mg blend by weight, but it prints no amount.
The math is short. Caffeine is printed at 5 mg in fifth place. A line listed before it cannot weigh less than 5 mg, so muira puama holds at least 5 mg. The four lines after caffeine hold at most 20 mg together, so the first four hold at least 57 mg between them, which is at least 14.25 mg each on average.
An even split of the blend would give each line about 9.1 mg. Being first, muira puama likely holds more than that. How much more is the maker's secret. U.S. rules allow a blend to hide single amounts (21 CFR 101.36 (eCFR)).
Evidence03
What does the evidence say about muira puama?
The evidence is limited. The source we read says trials do not give suitable dosages and side-effect research is limited (Drugs.com, Muira puama).
| Question | Answer |
|---|---|
| Traditional use | Male tonic and stimulant |
| Human trials for sexual dysfunction | Limited; no firm evidence |
| Established dose | None; trials give no suitable dosage |
| Safety data | Limited; no contraindication listed, which is not the same as none |
| Studied in Maxforce | No |
The source page shows no publication date, so we cannot confirm how current it is. That is one more reason to treat muira puama's reputation as a starting point for a question to a doctor, not an answer.
Cautions04
Is muira puama safe?
Safety data are limited, so nobody can say. No contraindication is listed in the source we read, but that is a gap in knowledge, not a clean bill of health (Drugs.com, Muira puama).
Take the usual cautions. The Maxforce label asks anyone who is pregnant or nursing, on medications or with a medical condition to consult a doctor first. It also says to stop and consult a doctor if any adverse reaction occurs. Keep taking prescribed medicine.
- Muira puama sits first in a blend that also holds caffeine, ashwagandha, L-arginine and horny goat weed.
- Any reaction could come from any of the nine lines, so a log helps a doctor.
- Combination products have no separate safety data for muira puama alone.

How does muira puama compare with the other first-place lines?
It leads a group of four lines that must hold at least 57 mg between them, and it has the weakest data of the four.
| Place | Line | Evidence in the sources |
|---|---|---|
| 1 | Muira puama | Limited; no dose (Drugs.com, Muira puama) |
| 2 | Maca | A few small trials (MSK, Maca) |
| 3 | Catuaba | Lab and rodent only (Antioxidant, anticholinesterase and antifatigue effects of Trichilia catigua (BMC CAM, 2018)) |
| 4 | Green tea | Not a sexual-function ingredient (NCCIH, Green Tea) |
The pattern is worth noticing. The four biggest shares of the blend are the lines with the least human evidence for the purpose the product is sold for.
Ask your doctor06
What should you ask a doctor about muira puama?
Ask whether it interacts with your medicines, whether your conditions rule it out and whether a tested treatment would serve you better.
Bring the label
Show the nine lines and the 82 mg blend. Say that only caffeine has a printed amount.
Ask about your medicines
Safety data are limited, so a doctor must rely on judgment.
Ask about the goal
If the goal is sexual function, the cause matters more than any herb (NIDDK, ED symptoms and causes).
The other lines07
What are the other ingredients in Maxforce?
Eight more lines follow muira puama: maca, catuaba, green tea, caffeine, ashwagandha, L-arginine, tribulus and horny goat weed.
Each has its own page with the place, the dose math and the sources. Start with maca, the second line, or read the ingredients overview.
FAQ08
Maxforce questions people ask
Is muira puama the main ingredient in Maxforce?
It is the first of nine lines, so it is likely the largest share of the 82 mg blend. But the label prints no amount, so we cannot say how large. Caffeine is the only line with a printed amount.
What is muira puama used for?
Traditionally it has been used as a male tonic and stimulant. Drugs.com says clinical evidence for sexual dysfunction is limited. It is not an approved treatment for any condition.
What dose of muira puama is used in studies?
No suitable dose has been established. The source we read says clinical trials do not provide suitable dosages. A Maxforce gummy holds at least 5 mg, but that figure is not compared with any study.
Does muira puama have side effects?
Research on side effects is limited, so we cannot list rates. No contraindication appears in the source we read. If you notice a reaction, stop and consult a doctor, as the label directs.
Is muira puama the same as potency wood?
Yes, potency wood is a marketing nickname for muira puama, from the Amazon. The nickname reflects a reputation, not tested potency, and the label uses the plain name.
Is muira puama safe with medicines?
Safety data are too limited to say. Because muira puama is part of a blend, the interaction risks that matter in Maxforce come from other lines, such as L-arginine. Ask a pharmacist and bring the label.
