L-Theanine is natural amino acid which is commonly found in tea leaves, such as green and black tea. It can also be found in pill or tablet form.  Studies show that L-Theanine may affect levels of various chemicals in the brain, which include dopamine and serotonin.  These two neurotransmitters influence mood, sleep, emotion, and cortisol which helps the body deal with stress.

The majority of L-Theanine's benefits are a result from the effects of elevated levels of GABA , serotonin, and dopamine in the brain.  All three of these are neurotransmitters that work to regulate mood, emotions, and sleep.  Increasing these neurotransmitter levels can also result in relaxation and calmness.  

L-Theanine enhances alpha brain waves, which can result in a state of being alert and creative. Many users love the combination of being alert and relaxed.  L-Theanine is often very effective when taken with caffeine.  Taking the two together enhances both cognition and mood, without the ultimate crash of taking caffeine by itself.
