Enhances mood and cognitive function

With its positive effects on mood, L-Theanine can help users feel more relaxed and focused, which is essential in creating a calm bedtime routine conducive to sleep.

3. How L-Theanine Works

L-Theanine works by influencing the levels of certain neurotransmitters. When consumed, it crosses the blood-brain barrier and stimulates the production of alpha waves, which are known to promote relaxation and focus.
