Strong

Several good studies agree

Why this rating

Strong for performance (hundreds of RCTs; ISSN position stand). Emerging for the sleep-loss angle (one crossover RCT, replicated 2026).

In short

The best-studied performance supplement there is. One study also found that a single large dose helped people think more clearly after a night without sleep. It softens the hit of poor recovery.

The bottom line

Creatine monohydrate is the best-studied performance supplement there is. Beyond strength, a 2024 trial showed a single large dose partially reversed the cognitive and brain-energy deficits of a night without sleep. It won't raise your HRV, but it helps you perform on the days recovery falls short.

How it works

Buffers phosphocreatine so cells regenerate ATP faster — muscle and brain alike.

Who it helps, and who it doesn't

Anyone training; people with high cognitive load on short sleep. Lab creatinine rises harmlessly — tell your doctor.

What the studies measured

Every result, next to the line that means no effect

Each diamond is a study's best estimate. The thin line shows how sure the study was: the shorter the line, the more certain the result.

Each unit gets its own scale, so numbers are never mixed on one line. When a study gave no range, we leave it blank instead of inventing one.
