Why Tongkat Ali for Hormones
Tongkat Ali plays a important role in hormones. Tongkat Ali (Eurycoma longifolia) is a Southeast Asian herb studied for testosterone support and stress. A 2022 meta-analysis (9 RCTs, 590 participants) found statistically significant increases in total testosterone compared to placebo.
What dose to look for
Clinical studies typically use 200–400 mg of tongkat ali. Most RCTs use 200–400 mg/day of standardized water extract (e.g., Physta, LJ100). Some studies go up to 600 mg/day. Products below this range may not deliver meaningful results.

Clinical research on Tongkat Ali (Eurycoma longifolia)
MODERATE for testosterone in older/hypogonadal men — small, heterogeneous, mostly manufacturer-linked · 200–400 mg/day standardized water extract (Physta/LJ100)
- •Meta-analysis of 5 RCTs found tongkat ali raised total testosterone (SMD 1.35, p=0.001), largest in men below 300 ng/dL — but heterogeneity was extreme (I²=87%) with small-study bias flagged. PubMed
- •Industry-linked RCT in men 50–70 with testosterone <300 ng/dL: 200 mg/day Physta for 12 weeks raised total testosterone from week 4 and improved aging-symptom and fatigue scores. PubMed
- •Industry-supplied RCT in moderately stressed adults: 200 mg/day for 4 weeks lowered salivary cortisol ~16%, raised salivary testosterone ~37%, and improved mood vs placebo. PubMed
- •Open pilot in active seniors: 400 mg/day for 5 weeks raised total and free testosterone; in women the free-T rise tracked a drop in SHBG — uncontrolled and hypothesis-generating. PubMed
