Muira Puama, nicknamed 'Potency Wood,' comes from the bark and roots of Ptychopetalum olacoides, a small tree native to the Brazilian Amazon. Indigenous communities along the Rio Negro have relied on it for generations as a tonic for sexual vitality, fatigue, and nerve-related complaints. Today it's used globally as a natural supplement for libido, energy, and cognitive support.

Muira Puama is thought to work through several overlapping pathways — it appears to support dopamine activity and nerve signaling in areas of the brain involved in sexual arousal and motivation. It may also help regulate the stress response, which is often a hidden driver of low desire and fatigue. Some of its plant compounds, including beta-sitosterol, interact with hormone-related pathways that influence testosterone balance and pelvic blood flow.

Standardized extracts (usually 4:1 or higher concentration) are the most studied and reliable form for libido and cognitive effects. Tinctures and liquid extracts offer fast absorption and are common in traditional use. Powdered bark capsules are widely available and practical for daily use. Traditional Amazonian preparations involve boiling the bark into a strong decoction, often combined with catuaba bark.

• Low libido (men and women)

• Sexual dysfunction in menopause
• Mental fatigue and brain fog
• Stress and nervous exhaustion
• Low energy and physical fatigue
• Age-related cognitive decline
• Joint pain and stiffness
• Depression and low mood

• Age-related sexual decline — regular use may help maintain healthy libido and sexual function as a preventive tonic in aging adults

Muira Puama is a rainforest tree bark extract with no meaningful food sources. However, you can support the same goals — libido, energy, and hormone balance — through your diet. Zinc-rich foods like oysters, pumpkin seeds, and beef support testosterone production. Dark chocolate and berries provide flavonoids that support circulation and mood. Brazil nuts (native to the same Amazon region) deliver selenium, which is important for reproductive health. Healthy fats from avocados, olive oil, and fatty fish support hormone synthesis overall. Foods to avoid: excessive alcohol and refined sugar, both of which suppress testosterone and blunt sexual drive.

• Mild digestive upset or nausea (usually dose-related)
• Elevated heart rate or mild stimulant effect in sensitive individuals
• Insomnia or restlessness if taken late in the day
• Headache (uncommon)
• Allergic reactions (rare)

• Recommended daily: 1,000–2,000 mg of dried bark extract per day, or 1–2 mL of a 4:1 liquid extract. Some clinical studies have used up to 1,250 mg of standardized extract twice daily.
• Best time of day: Morning or early afternoon is preferred to take advantage of its mild energizing effect and avoid sleep disruption.
• With or without food: Best taken with food to reduce the chance of stomach upset and support absorption of its fat-soluble compounds.
• Time to effect: Noticeable changes in libido or energy may appear within 2 weeks; fuller benefit typically emerges after 4–8 weeks of consistent use.
• How long to take it: Can be used continuously for up to 3 months; consider a 2–4 week break before resuming. Cycling helps maintain sensitivity to its effects.
