Popis: BackgroundThe findings from randomized clinical trials (RCTs) examining the effect of magnesium supplementation on depression are inconsistent. We decided to conduct a meta-analysis that summarizes all the evidence on the impact of magnesium supplementation on depression scores in adults with depressive disorder.MethodsWe conducted a systematic search in the online databases using all related keywords up to July 2023. We included all randomized clinical trials examining the effect of magnesium, in contrast to placebo, on depression scores.ResultsFinally, seven clinical trials were included in this systematic review, building up a total sample size of 325 individuals with ages ranging from 20 to 60 years on average. These RCTs resulted in eight effect sizes. Our findings from the meta-analysis showed a significant decline in depression scores due to intervention with magnesium supplements [standardized mean difference (SMD): −0.919, 95% CI: −1.443 to −0.396, p = 0.001].ConclusionOur review suggests that magnesium supplementation can have a beneficial effect on depression. Future high-quality RCTs with larger sample sizes must be run to interpret this effect of magnesium on depression in clinical settings.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?RecordID=447909.
