L-Theanine benefits
L-theanine is an amino acid found naturally in tea, especially green tea. Potential benefits include:
Relaxation and stress support — may promote a calmer feeling without strong sedation.
Focus and concentration — may help attention, particularly when combined with caffeine.
Sleep support — may help relaxation and sleep quality in some people.
May reduce occasional anxiety symptoms — evidence suggests a possible calming effect, but it isn't a treatment for anxiety disorders.
Balances caffeine effects — some people use it with coffee or tea to support smoother focus and reduce caffeine-related jitteriness.
