The Claim
Four weeks of daily 400 mg Tongkat Ali supplementation has no effect on handgrip strength, mood, sleep quality, or psychomotor vigilance in exercise-trained adults.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking 400 mg of Tongkat Ali daily for four weeks does not change handgrip strength, mood, sleep quality, or reaction time in adults who regularly exercise.
See the scientific wording
Four weeks of 400 mg daily Tongkat Ali supplementation does not improve handgrip strength, mood, sleep quality, or psychomotor vigilance in exercise-trained adults, indicating no ergogenic or psychological benefit in this population.
Taking 400 mg of Tongkat Ali daily for four weeks does not change muscle signaling, hormone levels, brain activity, or sleep regulation in trained adults, so strength, mood, sleep, and alertness stay the same.
What the research says
1 studyStudy: The Effect of Tongkat Ali Supplementation on Body Composition in Exercise-Trained Males and Females
Scientists gave 400 mg of Tongkat Ali daily to trained athletes for four weeks and found no improvement in strength, mood, sleep, or alertness compared to those who took a sugar pill. So, it doesn’t seem to help.
