Often associated with physical strength and muscle mass, creatine could also impact our state of mind.
Some studies have shown that it could play a role in managing mood disorders, particularly in the context of depression. This is still an underexplored but promising area of application. Let us explain!
Understanding Creatine Beyond Muscles
Creatine is a compound synthesized in the liver from three amino acids: arginine, glycine, and methionine. It is also found in food, particularly in red meat and fish.
In the body, it is stored in muscles and the brain as phosphocreatine, where it participates in the regeneration of adenosine triphosphate (ATP), the energy molecule used by all cells. While this energetic role is well known for muscle fibers, it is much less so for neurons… yet, the brain is one of the organs most demanding of ATP.
Creatine and Mood Disorders: What Does Science Say?
Research on the link between creatine and depression is still young, but it is already supported by several clinical trials and meta-analyses.
- Double-blind placebo studies have observed that creatine supplementation (often 3 to 5 g/day of creatine monohydrate) could improve depressive symptoms in certain populations, particularly women suffering from major depression and individuals with bipolar disorders.
- The main hypothesis is that, in some individuals, creatine optimizes ATP production in neurons, thereby supporting cognitive functions and emotional balance.
These effects appear to be more pronounced when used as a complement to medical treatment, rather than as a sole solution.
Other Fields of Study: From the Brain to Neuromuscular Diseases
In addition to depression, creatine is also being studied for its potential in Parkinson's disease, certain muscular dystrophies, and amyotrophic lateral sclerosis (ALS). Although results vary, this research confirms that creatine acts beyond just the muscles.
Dosage, Form, and Duration of Use
Most trials use creatine monohydrate, the most studied and validated form. Doses range between 3 and 5 g per day, sometimes more in a medical context, under professional supervision. Potential effects on mood seem to manifest in the long term, after several weeks of regular intake.
Caution and Medical Supervision
Even if the results are encouraging, creatine is not an antidepressant. Any use in the context of mood disorders must be done in agreement with a healthcare professional, as a complement and not a replacement for validated medical approaches.
In Summary
Creatine, well-known for optimizing physical performance, could also have a positive impact on mood and certain brain functions. Studies have shown real potential, but it is still being explored.
While awaiting more solid evidence, it remains a safe and well-tolerated dietary supplement for healthy adults, offering benefits beyond the gym.
