What the research shows.

Systematic review and meta-analysis of 60 studies (n=6,894) on valerian for sleep and associated disorders. Meta-analysis of 10 placebo-controlled RCTs found a combined effect size of 0.36 for subjective sleep quality improvement. Subgroup analysis favored whole root preparations (ES=0.83) over extracts (ES=0.10). No severe adverse events reported.Shinjyo et al., Journal of Evidence-Based Integrative Medicine, 2020
Systematic review and meta-analysis of 16 RCTs (n=1,093) evaluating valerian for sleep quality. Dichotomous sleep quality outcomes from 6 studies showed valerian users had an 80% greater relative risk of reporting improved sleep (RR=1.8, 95% CI 1.2-2.9) compared to placebo, with no significant side effects.Bent et al., American Journal of Medicine, 2006
