⚖️ Thin evidence — read the needle loosely. The score shows which way the studies lean, but there are too few independent, high-quality ones to place it firmly. Expect this to move as better evidence arrives.

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.

🧭 Read this score with how it was built in mindConfirmation now has to come from studies that tested the claim itself

Only one trial has tested creatine added to an antidepressant. The two other supporting studies measured dietary creatine intake across the general population and depression-like behaviour in rats with colitis, and the one pooled review of adjunct trials found that same single trial. The largest meta-analysis, mostly of creatine used alone, found a benefit below the threshold considered clinically meaningful at very low certainty.

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.

observational supports low Review: creatine — particularly as an adjunct to antidepressants — shows promise for treating depression.

2025 · Food & function
animal supports moderate INDIRECT (intervention + outcome: no antidepressant adjunct, and the endpoint is depression-LIKE behaviour in a colitis model, not depression symptom scores). Rat chronic DSS colitis: oral creatine reduced colitis severity and prevented motor deficits, anxiety- and depression-like behaviours in both sexes.

observational mixed low Review: preclinical and early clinical evidence supports a beneficial role of creatine in depression management.

2025 · The British journal of nutrition
meta-analysis mixed moderate INDIRECT (intervention: 'mostly monotherapy not adjunct-specific', so it does not test this claim's adjunct design). Meta-analysis of 11 trials, 1093 participants: SMD -0.34 (95% CI -0.68 to -0.00), GRADE very low, equal to 2.2 HDRS-17 points and BELOW the 3.0-point minimal important difference. The best-powered synthesis available reads sub-threshold and uncertain.

observational supports low INDIRECT (intervention + population: dietary creatine INTAKE in general US adults, not supplementation as an adjunct to an antidepressant). Cross-sectional NHANES: higher dietary creatine intake associated with lower prevalence of depression.

RCT mixed moderate Systematic review of 5 RCTs (6 articles, CrM n=126 vs placebo n=112) testing creatine 2-10g/day for 4-8wks as adjunct to SSRI/escitalopram or CBT in MDD/bipolar depression. Adjunct-to-escitalopram (k=1, d=1.13) and adjunct-to-CBT (k=1) beat

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.
