L-Theanine is an amino acid found in the leaves of the green tea plant that reduces stress levels in the human body when taken as a dietary supplement.Tea has been used for thousands of years as both an herbal health aid and as a beverage central to cultural traditions in many societies. It creates changes in body chemistry credited with relaxation and rejuvenation, enhancing the ability to think and improving mood.The only other natural source of theanine in the diet comes from the mushroom. Theanine is made synthetically for use as a dietary supplement. It is a common ingredient in over-the-counter sleep medications because of its calming effect.Although tea contains as much caffeine as coffee, it has less of a stimulant effect because of theanine. Research shows that the amino acid neutralizes what can be the jagged bad effects of caffeine without reducing the heightened mental alertness and fat-burning advantages of the chemical.Sleep studies have shown that theanine relaxes the body and calms the mind prior to sleep, which is very effective against cases of insomnia. Once asleep, research found that subjects did not sleep longer but did sleep better, reporting improvements in sleep quality, recovery from exhaustion and feeling refreshed upon awakening.Theanine has also been found to have a positive effect on mood, believed to be a benefit tied to the amino acid's function in regulating levels of serotonin and other neurotransmitters in the brain.

How Come I've Never Heard of This Before???
You gotta try this. If you get a little wiry using those pre-workout formulas that are mostly caffeine, then this is definitely the solution for you. Take it with a minimum dosage of caffeine, and it gives you steady, focused energy. It's also good for those nights when you're having a hard time getting to sleep. But I wouldn't use it for both reasons continuously, because it loses it's effect, or rather you build a tolerance for it, if you take too much of it within a short period. Even then, I would cycle it (on 3 weeks, off 3 weeks) to ensure it's max effectiveness for as long as possible.
