Single-Dose Creatine Reduces Cognitive Decline from Sleep Deprivation
TL;DR
A single dose of creatine can help maintain cognitive performance during acute sleep deprivation, but it's not a substitute for sleep.
Single-Dose Creatine Reduces Sleep Deprivation-Induced Cognitive Decline
A study in Nutrients tested whether a single dose of creatine could offset the cognitive impairment caused by sleep deprivation.
Creatine is well-known in sports nutrition for supporting ATP production — your cells' energy currency. The brain is highly energy-dependent, especially under stress like sleep loss.
The study found that participants who took creatine before a period of sleep deprivation showed better cognitive performance than those who didn't. Think of it like a power bank for your brain — it doesn't replace charging, but it gives you a buffer.
Takeaway: If you're facing an unavoidable all-nighter, a single dose of creatine might help you stay sharp. But it's not a long-term solution — nothing replaces actual sleep.
