The Claim
L-Theanine is often promoted as a supplement that can improve sleep quality and help individuals achieve deeper sleep.
Origin
This belief likely arises from its calming properties and its use in combination with other sleep aids, leading to assumptions about its direct role in sleep improvement.
What Science Says
Research, including pilot studies and randomized trials, suggests that L-Theanine may have a mild effect on sleep quality, particularly in reducing sleep disturbances. However, its impact is generally modest compared to more direct sleep aids.
Verdict
Mostly False
