Review of Creatine's Impact on Depression
A review of six scientific studies led by Bassam Jerius Fares from the University of Ottawa examined how creatine affects depression. The trials were conducted across multiple countries, including South Korea, the United States, Brazil, Israel, and India. A total of 238 participants took part, with 126 receiving creatine and 112 receiving a placebo. The average age of participants was 36, and the majority were women.
Four of the studies focused on individuals with major depressive disorder, while one trial included participants with bipolar disorder experiencing a depressive episode. In two studies involving women with major depressive disorder, creatine showed a positive effect. For instance, in one trial, participants took 5 grams of creatine daily alongside escitalopram, and in another, creatine was combined with cognitive behavioral therapy. One of these studies lasted eight weeks.
Study Results
However, three other studies found no significant benefit from creatine use. One revealed that neither 5 nor 10 grams of creatine per day helped with treatment-resistant depression, and another found no advantages among adolescent girls. Among participants with bipolar disorder who took creatine, two cases developed hypomania or mania. Reported side effects were limited to mild digestive discomfort.
'The signal looks interesting, but it is not yet a definitive conclusion. Two studies showed a positive result, three did not. This is not the kind of evidence that changes clinical practice. But it suggests that this question deserves further investigation,' emphasized Bassam Jerius Fares.
Despite some positive findings, further research is needed to better understand creatine's role in depression treatment.
The results of this review point to a possible future for creatine in managing depression, but the mixed findings highlight the need for additional studies. While positive effects were observed in some participants, most trials did not confirm its effectiveness. This underscores the importance of continued work in this area to determine when creatine might be helpful and when it is not.
