L-Theanine is a fascinating natural compound found in tea leaves, known for promoting calm without drowsiness — making it ideal for nighttime use.
L-Theanine increases alpha brain wave activity, the neural pattern of wakeful relaxation. It helps transition your mind from active thinking into a calmer state that naturally leads to sleep.
Beyond brain waves, L-Theanine increases GABA, serotonin, and dopamine while reducing excitatory neurochemicals. This multi-neurotransmitter action creates a broadly supportive environment for relaxation.
Clinical studies show L-Theanine improves sleep quality, reduces sleep latency, and decreases nighttime awakenings. Doses of 200 to 400 mg taken 30 to 60 minutes before bedtime are most effective.
Yu Sleep includes L-Theanine alongside GABA, 5-HTP, and low-dose melatonin in a fast-absorbing sublingual format. Learn how they work together or try it risk-free.
