- All studies were randomized, double-blind, placebo-controlled trials, enhancing the reliability of the findings.
- Sample sizes were relatively small, which may limit the generalizability of the results.
- Studies were conducted over short durations (4 to 12 weeks); long-term effects remain unknown.
- Further large-scale, long-term studies are needed to confirm these findings and assess the safety and efficacy of Tongkat Ali supplementation over extended periods.
