Eurycoma Longifolia Extract: The Ultimate Guide to Malaysia’s “Natural Testosterone Booster”

1. What is Eurycoma Longifolia Extract?

Eurycoma Longifolia Extract, derived from the roots of the Eurycoma longifolia plant, is a premier adaptogen revered as “Malaysian Ginseng” または “Tongkat Ali” (Malay for “Ali’s Walking Stick”). This evergreen tree thrives in Southeast Asia’s acidic, sandy rainforest soils and features a distinctive unbranched trunk (4–18m tall) with umbrella-like leaf crowns 16. For centuries, indigenous communities have used its bitter roots to combat fatigue, enhance virility, and treat malaria 5. Modern science validates its bioactivity, primarily attributed to quassinoids (eurycomanone) and canthin-6-one alkaloids 18.

2. 原料、化学特性、技術仕様

Botanical Sources & Extraction

• Primary Source: Roots (highest bioactive concentration); leaves/stems secondary 14.

• Extraction Methods:

  • Water/ethanol solvent extraction → macroporous resin purification

  • Supercritical CO₂ for high-purity eurycomanone isolation (>10%) 710.

Key Phytochemical: Eurycomanone

3. Health Benefits, Optimal Dosage & Safety

Therapeutic Advantages

• Testosterone Enhancement: Increases free testosterone by 440% via inhibition of SHBG (sex hormone-binding globulin) and aromatase 510.

• Fertility Improvement: Boosts sperm motility by 44% and concentration by 62% in idiopathic infertile men 58.

• Stress Reduction: Lowers cortisol levels by 16–32% in moderately stressed subjects 58.

• Anticancer Activity: Induces apoptosis in HepG2 liver cancer cells via p53 activation 1.

• Ergogenic Effects: Increases muscle strength by 5–15% in athletes 5.

Dosage Recommendations

• Standardized Extracts: 200–400 mg/day of 100:1 extract (delivering 1–4 mg eurycomanone) 58.

• Therapeutic Use: Up to 600 mg/day for ≤12 weeks (clinical supervision advised) 8.

• Cycling Protocol: 5 days on, 2 days off to prevent receptor desensitization.

Highest-Potency Products

• 100:1–200:1 Root Extracts: Concentrated to 5–10% eurycomanone 710.

Safety & Precautions

• 禁忌: Prostate/breast cancer, pregnancy, hypertension (may interact with propranolol) 8.

• 副作用: Mild insomnia, gastric discomfort (dose-dependent) 5.

• Heavy Metal Risk: Source from GMP-certified suppliers to avoid lead/mercury contamination 8.

• Clinical Gaps: Long-term safety data (>1 year); dosing optimization for women.

• 持続可能性: Tissue culture propagation to protect wild populations 15.

10. FAQ: Expert Answers

Q: Does Eurycoma increase estrogen?
A: No. Eurycomanone inhibits aromatase, reducing testosterone-to-estrogen conversion 8.

Q: Safe for hypertensive patients?
A: Contraindicated with blood pressure medications (e.g., propranolol) due to interaction risks 8.

Q: Optimal consumption time?
A: Morning with fatty meals (enhances quassinoid absorption).

Q: When to expect results?
A: Libido enhancement in 5–7 days; testosterone optimization requires 4–12 weeks 5.
