A 2026 study links high-quality kava tea to reduced anxiety and better sleep, but warns of possible liver risks with long-term use.
A new study published in February 2026 finds that regular consumption of high-quality kava tea may help reduce symptoms of anxiety and improve sleep quality in adults, according to researchers at the University of Hawaii.
The findings, based on a 12-week trial involving 150 participants, suggest kava's active compounds, known as kavalactones, have a calming effect without causing drowsiness.
Experts caution that long-term use should be monitored due to potential liver risks, and recommend choosing products tested for purity and standardized kavalactone content.
