# The role of brain creatine in behavioral health conditions

## TL;DR

This review explores how brain creatine may help with mental health conditions like depression and anxiety by supporting brain energy and as a potential treatment.

## Contribution

The paper provides a comprehensive review of creatine's role as a biomarker and therapeutic agent in psychiatric disorders.

## Key findings

- Creatine supports brain energy through the creatine kinase-phosphocreatine system.
- Deficits in brain bioenergetics are linked to psychiatric illnesses.
- Supplementing creatine shows potential therapeutic benefits in several mental health conditions.

## Abstract

Creatine, as a naturally occurring organic compound, has gained attention for its potential role in psychiatric health. The creatine kinase-phosphocreatine energy buffer system plays a crucial role in maintaining energy supply in the brain. Brain bioenergetic deficits, particularly those related to mitochondrial dysfunction, plays a critical role in the pathophysiology of psychiatric illnesses. A growing body of literature has focused on the potential therapeutic role of creatine supplementation in psychiatric illnesses. This review summarizes findings from preclinical, epidemiological, clinical and neuroimaging studies to examine creatine’s role as both a biomarker and therapeutic agent in psychiatric disorders, including Major Depressive Disorder, Anxiety Disorders, Posttraumatic Stress Disorder, and Substance Use Disorder.
