The interesting thing about Theanine is that the substance is found in (and derived from) tea. It is responsible for the slightly exotic taste, especially in green tea. Ever since, this was first separated from the gyokuro leaf in 1950 in Kyoto, Japan the health effects have been examined and researched.

Essentially, L-Theanine is an amino acid which crosses the blood brain barrier and produces a calming effect within the brain. The production and release of GABA and dopamine are increased, which intensify this calming effect. An additional effect is the increase in the production of alpha brain waves. Together, these chemicals and brain waves are responsible for creating a feeling of relaxation and alertness, but without any kind of drowsiness or stimulant effects.

The health effects of Theanine are numerous. There has even been research supporting the ability of this amino acid to help boost immune system function, making gamma t-cells more effective at attacking germs and other nasty body invaders. Healthy cardiovascular function is supported and L-Theanine is a natural anti-oxidant. Symptoms of PMS are reduced, and more restful sleep has been reported.

I am a student trying to finish my classes in a shorter time frame. I was having trouble finding time to relax and study. I was so stressed out that anything I studied got lost. Now that I am using this I am able to sit down and read or study a concept and then ponder and understand it. It works!

This really helps for stress and overwhelmed feelings. It allows me to think more rationally. I found myself feeling happy for no reason - just felt better than usual. Definitely noticed the difference when I ran out. Also, it helps at bedtime to allow me to sleep better. I mix it in with my tea and its been nothing but good for me. The price was a very good value too.

I was having trouble getting to sleep at night. My mind wouldn’t shut off. It was like I was racing through all the problems and concerns I had and not getting anywhere. Then because I was tired I couldn’t complete the tasks I had the next day. Now I can relax and get to sleep. I stay asleep so that they next day I awake feeling so good.

I am part of the Muscle Builder Team. Now I have used this product in the past and absolutely loved it. Took the pounds off for the summer. Great energy and focus. Makes you sweat a ton. No jitters and decreased hunger. What else could you ask for in a fat burner?

I received a sample from one of my good friend of L Theanine Bulk Powder to try out and in about a week and a half I was already feeling positive effects.

I had more energy throughout the day and I actually shed a couple pounds.

Works well.

My wife and I both find l-theanine to be an excellent way of calming ourselves when we are feeling a bit 'frazzled'. It is particularly useful if you have drunk too much coffee, and have the caffeine jitters. It is not a sedative, but just calms and adds certain serenity.

We love it. Value for money is second to none.
