Potential Benefits

L-Theanine, also simply known as Theanine, was discovered as an element of green tea in 1949. Currently, it is sold as a dietary supplement.
The research on the mechanical operations of L-Theanine has led scientists to determine that it contains a host of potential benefits related to brain functionality.  Some of these potential benefits include:

These benefits tie into L-Theanine’s demonstrated psychoactive properties, as it has been shown through scientific study that it can act on the central nervous system to alter mental cognition, mood, and behavior.  For example, high doses of L-Theanine – that is doses that are higher than the typical dose that is found in a 20 mg cup of black tea – have demonstrated a facility to relax the mind without promoting drowsiness as a side effect.

Another study concluded that a 50 mg dose of L-Theanine caused a greater increase in alpha activity; a type of brain-related activity that plays a vital role in attention.  Other studies have also yielded enhancements relating to cognition and mood when L-Theanine was combined with caffeine.
