Kava for Stress Relief

Research suggests that kava may support stress relief and relaxation, with available evidence drawing from a large-scale survey and a narrative review of dietary supplements rather than controlled clinical trials. The 2026 survey of 2,000 U.S. adults found that 88.1% of kava users rated it as effective for relaxation and stress relief, with users commonly reporting feelings of happiness and calm, though this type of self-report data reflects user perception rather than experimentally measured outcomes. A 2005 review of functional foods and supplements noted that kava, among other herbal ingredients, showed preliminary evidence of lowering stress reactivity, but the authors emphasized that the research methodologies available at the time were insufficient to support firm conclusions. Overall, the current body of evidence on this specific use is limited in study design quality and scope, and more rigorous controlled human trials would be needed to draw stronger conclusions about kava's role in stress management.
