Why it works

Melatonin tells the body clock it is night. Its best evidence is for shifting sleep timing, with modest gains for general insomnia [1][2]. L-Theanine works on a different problem, the stress that keeps people awake, and a meta-analysis found small improvements in subjective sleep [3].

How they work together

The two have no documented interaction and work through different mechanisms: one on timing, one on arousal.

Worth knowing

Timing does most of the work for melatonin. Taken at the wrong time, it can push the clock the wrong way [1]. Supplement doses also often do not match the label [4].
