The Claim

A single 0.35 g/kg dose of creatine administered during sleep deprivation reduces cerebral ATP-β levels by 8–14% across multiple brain regions, which is associated with improved cognitive processing speed and reduced fatigue.

Source: Single dose creatine improves cognitive performance and induces changes in cerebral high energy phosphates during sleep deprivation

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.

How it works
1 study reviewed
In plain English

Taking a specific dose of creatine while sleep-deprived is linked to a measurable drop in ATP-β levels in the brain, along with faster thinking and less tiredness.

See the scientific wording

During sleep deprivation, a single 0.35 g/kg creatine dose reduces cerebral ATP-β levels by 8–14% in multiple brain regions, suggesting enhanced ATP turnover to meet energy demands, which is associated with improved cognitive processing speed and reduced fatigue.

What the research says

1 study

  1. Study: Single dose creatine improves cognitive performance and induces changes in cerebral high energy phosphates during sleep deprivation

    This study found that taking a big dose of creatine while sleep-deprived helps the brain make more energy quickly, which makes people think faster and feel less tired. So yes, creatine helps the brain cope with lack of sleep.
