A True Suntheanine L-Theanine Review

One of my friends Lisa, a busy mom just like me, was telling me about how hard it was for her to get even six straight hours of sleep a day. She would toss and turn the whole night while she was sleeping and wake up every two hours or so and then have a terrible time going back to sleep!

The lack of sleep caused her to be restless, anxious, lacking in concentration and forgetful. That is no way to live your life for sure! She was desperate to get some solid sleep and not feel so run down and stressed out all the time and that’s when I told her about Suntheanine L-Theanine.


Ever since Lisa discovered Suntheanine L-Theanine, she not only sleeps soundly for seven or more hours at a stretch, she is fresh and alert when she wakes up. She feels calm, sharp, is no longer mentally tired, and leads an active and satisfied life with her family. Doesn’t that sound wonderful?!

My friend Lisa’s story is not unique. There are a LOT of men and women who have shared their stories on the Internet, and have talked about how this wonder drug, Suntheanine L-Theanine has had such a transformative effect on their lives. So what is this Suntheanine L-Theanine? Read on to find out.

Origins of Suntheanine L-Theanine

The origins of Suntheanine L-Theanine are found in green tea. The Japanese have always felt that green tea has a calming influence on people and makes them alert, sharp and relaxed. Scientists discovered that the chemical compound causing this is an amino acid called L-Theanine that is present in green tea. So what did they do with that knowledge? They synthetically produced a 100% concentrated product of L-Theanine, which maximizes the relaxation inducing capabilities of green tea and called it Suntheanine L-Theanine.

Suntheanine L-Theanine Ingredients

Apart from L-Theanine, Suntheanine L-Theanine also has organic cane sugar, xylitol, stearic acid, silica, natural fruit flavor (pineapple, banana, pomegranate, mango, and passion fruit), citric acid, and magnesium stearate (vegetable grade). We focus primarily on L-Theanine as it is the most important ingredient in Suntheanine L-Theanine.

L-Theanine may also be called as 2-Amino-4- (ethylcarbamoyl) Butyric Acid, 5-N-ethylglutamine, Gamma-glutamylethylamide, L-Theanine, L-Théanine, N-Éthyl-L-Glutamine, Teanina, Théanine. According to WebMD, L- Theanine is an amino acid found in green tea and is found to cure anxiety, high blood pressure, preventing Alzheimer’s disease and making cancer drugs more effective.

How does L-Theanine work?

WebMD describes it very well by stating that “Theanine has a chemical structure very similar to glutamate, a naturally occurring amino acid in the body that helps transmit nerve impulses in the brain. Some of the effects of theanine appear to be similar to glutamate, and some effects seem to block glutamate.” What does that mean in plain old English?

It means that L-Theanine Suntheanine causes tranquility in people, reducing overall stress and making them less anxious. It induces relaxation in people, restores mental calmness, reduces stress, sharpens the memory, increases the state of alertness and allows for sound sleep. It has helped me and so many others I know that suffered from anxiety, stress and restlessness for years! Going without Suntheanine L-Theanine is definitely not an option for me.

This holds true with any medical condition. The dosage may vary from person to person. It is generally considered safe to have 50 mg to 200 mg of Suntheanine L-Theanine a day.
