L-Theanine - Sex Drive Support / Dopamine / Glutamate
The effects of theanine are not imaginary. It readily crosses the blood-brain barrier of humans and exerts subtle changes. An increase in alpha waves has been documented and the effect has been compared to getting a massage or taking a hot bath. Theanine is different than kava-kava in that it doesn't cause drowsiness. And, unlike tranquilizing drugs, it doesn't interfere with the ability to think. Studies on rodents show just the opposite: Theanine enhances the ability to learn and remember. By shutting down the worry mode, theanine increases concentration and focuses thought. This is the concept behind the Japanese tea ceremony which causes a person to focus on the moment. Consider this: The risk of mortality for Japanese women who practice tea ceremony is half of other Japanese women. The Japanese are already the longest-lived people on earth.
Theanine is a caffeine antagonist (against). The effects can readily be seen in EEGs of rodents given caffeine and then theanine. One of the things that theanine changes is GABA -- a brain chemical known for its calming effect. Theanine increases GABA, while caffeine decreases it. GABA doesn't just relax, it also creates a sense of well-being. Theanine's ability to increase this brain chemical helps create better moods. Theanine also increases dopamine levels -- another brain chemical associated with mood-enhancing effects without side effects and increased feelings associated with sex drive.

Theanine is structurally similar to the amino acid, L-glutamic acid. The similarity enables theanine to physically block glutamate (which is a version of glutamic acid). Although researchers aren't positive how theanine works, however, they theorize that theanine blocks the NMDA receptor which is the doorway that glutamate uses to enter cells. Because of the similar structure, theanine can also fit in this doorway by blocking access to glutamate. Even though it can fit in the doorway, theanine does not have the same effect on the cell as glutamate does. Rather than causing damage, theanine acts like a shield against damage with no known side effects.
One of the protective factors in the Japanese diet is green tea. Green tea contains a much higher concentration of theanine than other teas. L-Theanine supports healthy blood pressure. It works through its GABA-enhancing effects. Green tea extract contains a phytochemical known as GMA. Combining them together may have significant effects.
Theanine has multiple benefits with virtually no side effects. It's like zen in a bottle and its effects have been compared to tobacco or aromatherapy. Studies show that theanine is a non-toxic, highly desirable mood modulator that can be enjoyed by every adult.
