The Claim

Creatine supplementation increases brain creatine levels in humans.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Taking creatine supplements raises the amount of creatine in the human brain.

Creatine supplementation increases brain creatine levels in humans.

Why this might work

When someone takes creatine pills, the creatine enters the bloodstream, crosses into the brain through a specific transporter, and builds up inside brain cells where it can be used to store and supply energy.

What the research says

2 studies

  1. Study: Effects of Creatine Monohydrate Augmentation on Brain Metabolic and Network Outcome Measures in Women With Major Depressive Disorder.

    Taking creatine supplements helped women’s brains work better, and one key sign of this improvement is a chemical called NAA that only goes up when there’s more creatine around to help energy production. So yes, creatine pills likely raised creatine levels in their brains.

  2. Study: 450 Eight weeks of creatine monohydrate supplementation is feasible and associated with increased brain creatine in patients with AD

    Taking creatine supplements made the brains of people with Alzheimer’s have more creatine — like adding more fuel to a battery. The study measured this directly and found a clear increase.
