Creatine Supplementation in Depression: Mechanisms and Clinical Outcomes
Can creatine supplements help treat depression?
Yes. Creatine supplements effectively help treat depression by improving brain energy metabolism and mitochondrial function, with clinical studies showing significant improvements in depression scores. Comprehensive review in Cureus examines mechanisms, efficacy, and clinical outcomes of this emerging therapeutic approach.
What the data show:
- Clinical evidence: Multiple trials demonstrate significant improvements in depression scores compared to placebo
- Best use: Particularly effective as adjunctive treatment, enhancing effects of conventional antidepressants
- Brain imaging: Creatine supplementation increases brain creatine and phosphocreatine levels, indicating improved energy metabolism
- Target population: Most effective in individuals with mitochondrial dysfunction or energy metabolism impairments, with women showing particularly strong responses
- Dosing: Typically 3-5 grams daily for maintenance after optional loading phase
- Mechanism: Creatine supports ATP regeneration (cellular energy currency) in brain cells, improving neural energy metabolism by enhancing phosphocreatine energy pools and mitochondrial function, which addresses underlying energy dysfunction that contributes to depression symptoms
A comprehensive review published in Cureus examines creatine supplementation in depression, analyzing mechanisms, efficacy, and clinical outcomes. Creatine is best known as a sports supplement, but emerging research suggests it may have significant benefits for mental health by playing a crucial role in cellular energy metabolism, especially in high-energy-demand tissues like the brain.
