Evidence detailsStudy limits, status, and safety context
Study summary: Evidence is strongest for circadian-timing uses such as jet lag and certain delayed sleep patterns; effects on general insomnia are more modest.
What to keep in mind: Product content can vary, and sedation, timing, pediatric use, interactions, and next-day impairment matter.
Potential benefits describe research questions, not a promise that a product will produce the same result in a person.
