Safety profile

5 studies reporting safety data

Across 5 clinical studies, no specific adverse events were quantitatively increased compared to placebo for valerian extract. Valerian was described as generally well tolerated in multiple studies, with side effects such as somnolence reported as mild and transient, and no serious adverse events documented.
