The Claim
Four weeks of daily 400 mg Tongkat Ali supplementation has no meaningful effect on lean body mass, fat mass, or percent body fat in exercise-trained adults aged 33 years on average with over 13 years of training experience.
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 lean body mass, fat mass, or body fat percentage in adults who have been regularly training for over 13 years.
See the scientific wording
Four weeks of daily 400 mg Tongkat Ali supplementation has no meaningful effect on lean body mass, fat mass, or percent body fat in exercise-trained adults aged 33 years on average with over 13 years of training experience, indicating it does not alter body composition in this population.
The body's muscle and fat tissue stay the same because the signals that build muscle or break down fat don't change when this supplement is taken, and the person is already trained and eating enough to maintain their current body shape.
What the research says
1 studyStudy: The Effect of Tongkat Ali Supplementation on Body Composition in Exercise-Trained Males and Females
People who took Tongkat Ali pills for four weeks didn't gain or lose more muscle or fat than those who took sugar pills — so the supplement didn't change their body shape.
