L-Theanine is a natural occurring amino acid found in the leaves of green tea. It is non-drowsy yet calming when taken during the day, but is also a highly effective sleep aid at night because it increases alpha brain wave activity, thus improving sleep quality by increasing time during REM sleep.

L-Theanine is rapidly gaining popularity in the west as an effective single supplement, and also for "stacking" or combining with other synergistic compounds. Studies have proven it to be very effective at increasing focus and concentration even more when combined with caffeine. Many more scientific studies are currently underway looking into L-Theanine's ability to reduce food and drug cravings by increasing dopamine. It has already been shown in a double blind study to reduce nicotine cravings and help with withdrawal. More scientific research is continuously coming out supporting L-Theanine as a highly effective and safe supplement for a wide variety of uses.
