From the Research
Tongkat Ali root (Eurycoma longifolia) is a safe and effective herbal supplement for improving male sexual health, boosting testosterone levels, and enhancing athletic performance, with a recommended dosage of 200mg daily of a standardized extract, as supported by the most recent and highest quality study 1. The supplement works by potentially increasing testosterone production, reducing sex hormone-binding globulin (SHBG), and decreasing cortisol levels. Some key points to consider when using Tongkat Ali include:
- Typical dosages range from 200-400mg daily of a standardized extract (usually standardized to 2-3% eurycomanone or 22% eurypeptides)
- The supplement should be taken consistently for at least 1-2 months to evaluate its effectiveness, preferably with meals to minimize potential stomach discomfort
- While generally considered safe for most healthy adults, side effects can include insomnia, irritability, and increased body temperature
- Those with hormone-sensitive conditions, heart issues, or those taking medications should consult a healthcare provider before use
- Cycling the supplement (4 weeks on, 2 weeks off) may help prevent tolerance development
- Quality matters significantly with this supplement, so choosing products from reputable manufacturers with third-party testing is important for effectiveness and safety, as shown in a systematic review and meta-analysis of clinical trials 1. Additionally, a 6-month, double-blind, placebo-controlled, randomized trial found that concurrent training and supplementation with Eurycoma longifolia significantly improved erectile function and increased total testosterone levels in men with androgen deficiency of aging males (ADAM) 2. It is also worth noting that Eurycoma longifolia has been shown to have potential in preventing and treating male osteoporosis due to androgen deficiency, by exerting proandrogenic effects and stimulating osteoblast proliferation and osteoclast apoptosis 3. However, the most recent and highest quality study 1 provides the strongest evidence for the effectiveness of Tongkat Ali in improving male sexual health and boosting testosterone levels.
