The Claim

A single 0.35 g/kg dose of creatine monohydrate administered during 21 hours of sleep deprivation increases cerebral total creatine relative to N-acetyl-aspartate (tCr/tNAA) by up to 6.1% in the left medial parietal region, indicating enhanced brain creatine uptake despite limited blood-brain barrier transport capacity and suggesting that acute metabolic stress may transiently facilitate creatine entry into neurons.

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

After 21 hours without sleep, taking 0.35 grams of creatine per kilogram of body weight increases the ratio of creatine to N-acetyl-aspartate in a specific region of the brain by up to 6.1%, suggesting that sleep deprivation may temporarily allow more creatine to enter brain cells than under normal conditions.

See the scientific wording

During 21 hours of sleep deprivation, a single 0.35 g/kg dose of creatine monohydrate increases cerebral total creatine relative to N-acetyl-aspartate (tCr/tNAA) by up to 6.1% in the left medial parietal region, indicating enhanced brain creatine uptake despite the blood-brain barrier’s limited transport capacity, suggesting acute metabolic stress may transiently facilitate creatine entry into neurons.

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

    When people stay awake for a long time, their brains get tired and run low on energy. This study found that taking a big dose of creatine (a natural supplement) helped the brain absorb more creatine than usual, giving it a quick energy boost even though the brain normally blocks it.
