The Claim
Citrulline supplementation has no significant effect on anaerobic endurance in male sub-elite badminton players beyond the first 24 hours of intervention.
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 citrulline supplements does not improve short bursts of high-intensity performance in male sub-elite badminton players after the first day of use.
See the scientific wording
Citrulline supplementation does not appear to significantly improve anaerobic endurance beyond the first 24 hours in male sub-elite badminton players, despite theoretical mechanisms involving nitric oxide and creatine synthesis, suggesting sport-specific or dose-dependent limitations.
Citrulline turns into arginine, which makes nitric oxide, which opens up blood vessels to deliver more oxygen and nutrients to muscles. This helps muscles work harder for a short time, but the effect fades after one day because the body adjusts and the extra blood flow doesn't last.
What the research says
1 studyCitrulline gave badminton players a short power boost after one day, but that boost disappeared after three days — so it doesn’t help with explosive moves over the long term, just like the claim says.
