Green Tea Amino Acid Aids Sleep, Study Shows
5 Nov
Summary
- L-theanine, found in green tea, modestly improved sleep onset.
- Study participants reported less reliance on sleep medication.
- The supplement also improved daytime function and reduced disturbances.
A small, four-week study has explored the potential sleep benefits of L-theanine, an amino acid naturally found in green tea. This compound is known for its calming effects without causing sedation.
The trial involved 30 participants who took either 200 mg of L-theanine or a placebo before bed. Results indicated that L-theanine modestly reduced the time it took to fall asleep. Participants also reported fewer sleep disturbances.
Compared to the placebo, L-theanine use was associated with less reliance on sleep medication. Additionally, participants noted improvements in daytime dysfunction, such as better alertness and enthusiasm.
While the study was small and had certain limitations, including its funding source, the findings are considered promising. L-theanine is noted for its safety profile and affordability, making it a potentially low-risk option for individuals seeking to improve their sleep.
