Creatine protects cognitive function during stress conditions

This small study (15 young - aged 20-28 years, healthy adults) tested whether a single large dose of creatine could protect thinking ability during one night without sleep. Results showed creatine mainly improved how fast people completed mental tasks (16-29% faster), but accuracy changed minimally—most tasks still showed errors with creatine, just slightly fewer than placebo. Only language and math tasks improved in correctness (6-10%). The small sample size and limited testing make these findings inconclusive and needing confirmation in larger studies.

This small study tested whether creatine supplements could protect brain function when 15 healthy adults breathed low-oxygen air for 90 minutes (simulating extreme high altitude).

The oxygen deprivation impaired attention, memory, and thinking speed.

Creatine supplementation (20g daily for a week) appeared to protect some attention performance, though the statistical evidence was weak and wouldn't survive rigorous correction for multiple comparisons.

It only tested one extreme, artificial stress condition rarely encountered in real life. The findings don't tell us whether creatine helps with everyday stressors like work pressure, poor sleep, or normal aging.
