What Is L-theanine and How Can It Help Me?
Medically Reviewed by Dr. Paris Kidd


Would you be interested in a natural plant substance that can reduce stress and worry while improving mood, focus, memory, and mental alertness? Meet l-theanine!

What Is L-theanine?

L-theanine is a unique amino acid that is not used to make proteins and naturally occurs in green tea. When consumed by humans, it can reduce tension and fosters a restful state without diminishing daytime alertness. It also can promote blood pressure stability against the over-excitability associated with stress.

Working by way of nerve cell receptors for GABA, glutamate, and other neurotransmitters, l-theanine has calming effects while preserving mental focus. It is rapidly absorbed and quickly shifts the brain toward a predominance of EEG alpha waves, which are associated with relaxation.

In clinical research, l-theanine has been found to help improve attention, mood, cognition, and the quality of sleep. As a natural relaxant, l-theanine reduces tension and promotes rest without diminishing alertness.

L-theanine is very well tolerated when taken by mouth and has been found safe in numerous clinical studies with both adults and children.

Benefits of L-theanine

Among its many benefits, l-theanine:

  • Improves focus and clarity
  • Doesn’t give you the jitters since it’s caffeine-free
  • Has a gentle, relaxing effect without making you sleepy
  • Can improve time to fall asleep, sleep duration, and sleep quality in children and adults

With such a variety of positive actions for overall brain and body health, BrainMD is proud to offer effective doses of L-theanine in several of our ultra-pure, brain directed supplements…
