The Claim
A 4-week supplementation with 200 mg/day of a standardized Tongkat Ali extract has no significant effect on body weight, body fat percentage, or liver enzyme levels in moderately stressed 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 200 mg of standardized Tongkat Ali extract daily for four weeks does not change body weight, body fat percentage, or liver enzyme levels in adults with moderate stress.
See the scientific wording
A 4-week supplementation with 200 mg/day of a standardized Tongkat Ali extract does not significantly alter body weight, body fat percentage, or liver enzyme levels in moderately stressed adults, indicating that the observed hormonal and mood effects are not secondary to changes in body composition or hepatic function.
A compound in Tongkat Ali binds to a protein that holds testosterone, freeing up more of it in the blood. This same compound also reduces the production of the stress hormone cortisol. The higher testosterone and lower cortisol change how the brain responds to stress, improving mood, but they do not cause the body to lose weight, fat, or affect the liver.
What the research says
1 studyTaking Tongkat Ali for four weeks improved mood and stress hormones but didn’t change body fat or weight — so the good feelings probably come from the supplement itself, not from losing weight or liver changes.
