creatine improves depression symptoms

In plain terms: Can creatine help with depression?

Part of: 🧪 creatine

RefutedContestedStrong support
consensus score 0.45

Maybe, as an add-on to antidepressants — one promising trial found it boosted recovery in women taking an SSRI. But that trial and its main support come from a single research group, so it isn't confirmed yet. Interesting, not established.

What the evidence shows

The strongest signal is as an add-on to antidepressants, not a standalone: a double-blind RCT found creatine augmentation of an SSRI improved response and remission in women with major depression, backed by mechanistic reviews and a population association.

Disagree, or know a study we missed?

We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
