Muira Puama Glycerite Liquid Extract
Also known as: Muira puama, potency wood, marapuama, Ptychopetalum olacoides
Overview
Muira puama, scientifically known as Ptychopetalum olacoides, is a plant native to the Amazon rainforest, particularly Brazil, where it has been traditionally used by indigenous populations as an aphrodisiac and nerve tonic. The glycerite liquid extract, derived from the plant’s bark and roots, contains bioactive compounds such as alkaloids (e.g., muirapuamine), sterols, and flavonoids. It is primarily utilized to enhance sexual desire, improve erectile function, and serve as a general tonic for fatigue and certain neurological conditions. While research on muira puama is emerging, it includes animal studies, a limited number of human clinical trials, and some systematic reviews focusing on herbal combinations that include muira puama. The current evidence base suggests potential benefits but is not yet robust or definitive.
Benefits
Muira puama shows potential for improving sexual function, particularly in men with psychogenic erectile dysfunction (ED). Clinical studies have reported improvements in libido and erectile function, with some showing increases in International Index of Erectile Function (IIEF) scores by 3–4 points after 8 weeks of treatment, leading to enhanced erectile rigidity and sexual satisfaction. In a study involving 262 men with sexual desire issues, 62% reported significant libido improvement within two weeks. Animal studies suggest that muira puama, especially in combination with other herbs, can improve age-related ED comparable to PDE5 inhibitors. Additionally, clinical observations indicate it may reduce fatigue and alleviate symptoms associated with sexual asthenia, potentially linked to testosterone deficiency. In vitro studies also suggest antioxidant and anti-inflammatory properties, which could contribute to its overall therapeutic effects.
How it works
Muira puama primarily functions as a central nervous system stimulant, which is believed to enhance sexual sensitivity and response. Its mechanism of action involves modulating neurotransmitters and hormonal pathways crucial for sexual function, potentially by increasing cyclic guanosine monophosphate (cGMP), a key molecule in the physiological process of penile erection. The alkaloids and flavonoids present in the extract are thought to exert antioxidant and anti-inflammatory effects, which may help protect vascular and neural tissues vital for erectile function. While specific bioavailability data for glycerite extracts are limited, glycerin-based preparations generally facilitate good absorption of water-soluble compounds, allowing the active constituents to exert their effects within the body.
Side effects
Muira puama is generally considered well-tolerated, with a low reported incidence of side effects. Minor adverse effects, observed in less than 5% of users, include sleeplessness, headaches, and heartburn. There are no firmly established significant drug interactions or contraindications; however, caution is advised for individuals using CNS stimulants or those with pre-existing cardiovascular conditions due to its potential stimulant effects. Safety data regarding use in pregnant or breastfeeding women are insufficient, and therefore, its use is not recommended in these populations. It is always advisable to consult with a healthcare professional before incorporating muira puama into one's regimen, especially for individuals with underlying health conditions or those taking other medications.
Dosage
Clinical studies investigating muira puama's efficacy have typically utilized doses standardized to the extract, often in combination with other herbs, administered orally twice daily. For glycerite liquid extracts, exact dosing is not yet standardized in scientific literature, and commercial products vary. Studies demonstrating benefits in men with erectile dysfunction have used combinations containing muira puama at doses equivalent to several hundred milligrams of extract daily, typically over an 8-week period. There is no established maximum safe dose, and caution is recommended with higher doses due to its stimulant properties. Consistent daily dosing over several weeks is generally necessary to observe therapeutic effects. No specific cofactors are reported as necessary for its absorption.
FAQs
Is muira puama effective alone or only in combinations?
Most human studies involve muira puama combined with other herbs; its isolated effects require further dedicated research to be fully understood.
How soon can benefits be expected?
Some studies report initial effects within 2 weeks, but typical treatment durations of 6–8 weeks are often needed for measurable and sustained improvement.
Is it safe long-term?
Long-term safety data for muira puama are currently limited; however, short-term use appears to be generally safe and well-tolerated.
Can it replace prescription ED medications?
Current evidence is insufficient to recommend muira puama as a direct replacement for PDE5 inhibitors, but it may serve as an adjunct or alternative in mild cases of ED.

It provides preclinical evidence for muira puama's potential in ED, though it was part of a multi-ingredient formula.
- https://oss.jomh.org/files/article/20250627-564/pdf/JOMH2025032002.pdf – This systematic review and meta-analysis suggests muira puama shows modest improvements in psychogenic ED and libido, acting as a CNS stimulant. It highlights the need for more high-quality randomized controlled trials to solidify the evidence base.
- https://pubmed.ncbi.nlm.nih.gov/10919969/ – This clinical study, though not an RCT, involved 262 men with libido and ED issues, reporting significant improvements in libido (62%) and ED (52%) after two weeks of muira puama treatment. It also noted better tolerability compared to yohimbine, providing early human observational data.
