creatine improves depression symptoms
In plain terms: Can creatine help with depression?
Part of: 🧪 creatine
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.
Evidence ladder
How far up the ladder this claim has climbed. A high consensus on a low rung means "consistent so far," not "proven in people."
Top evidence so far: Human trials (RCT / n-of-1)
How the studies fall
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. Promising, but the positive RCT and the supporting association come from a single research network (Renshaw/Utah), with no independent repl

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.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
