What this protocol does

A structured evening routine to transition from high-alert daytime mode to restful sleep preparation.

What to expect

Synthesized from research on this protocol's components. Individual response varies.

Week 1

Look for: Better subjective sleep quality and more refreshed mornings — L-theanine significantly improves overall subjective sleep quality scores and reduces subjective daytime dysfunction. Mood improvements are also reported.

Not yet expected: Major changes in sleep architecture beyond sleep efficiency — L-theanine does not significantly improve other sleep parameters beyond efficiency in studied populations.
