The Claim

Females exhibit greater cognitive protection than males following a single 0.2 g/kg creatine dose during sleep deprivation, with significant improvements in logic task performance, psychomotor vigilance, and language processing speed, indicating sex-specific differences in brain energy metabolism or creatine utilization.

Cause and effect
1 study reviewed
In plain English

After taking a single dose of creatine while sleep-deprived, females show better performance on tasks involving logic, attention, and language speed compared to males, suggesting biological differences in how the brain uses creatine for energy.

1 study
  1. Study: Single-Dose Creatine Reduces Sleep Deprivation-Induced Deterioration in Cognitive Performance

    This study found that when people stay up all night, women who took a small amount of creatine did better on thinking and reaction tests than men who took the same amount — suggesting their brains might use creatine more efficiently.
