The Claim

Creatine monohydrate supplementation at 5 g/day for 8 weeks, when combined with cognitive behavioral therapy, reduces depressive symptoms in adults with major depressive disorder not taking antidepressants, with a mean PHQ-9 score difference of 6.1 points compared to placebo.

In plain English

In adults with major depressive disorder who are not taking antidepressants, taking 5 grams of creatine monohydrate daily for 8 weeks along with cognitive behavioral therapy results in a 6.1-point greater reduction in depressive symptoms on the PHQ-9 scale compared to placebo.

See the scientific wording

Creatine monohydrate supplementation at 5 g/day for 8 weeks, when combined with cognitive behavioral therapy (CBT), significantly reduces depressive symptoms in adults with major depressive disorder who are not taking antidepressants, with a mean PHQ-9 score difference of 6.1 points favoring creatine over placebo.

Why this might work

Creatine enters the brain and helps store extra energy in a form that neurons can use quickly when they need it. This extra energy allows brain cells in the area that controls mood to work better, repair themselves, and communicate more effectively, which reduces symptoms of depression.
