L-Theanine, also simply known as Theanine, was discovered as an element of green tea back in 1949.  In 1964, Japan approved its unlimited use in all foods with the exception of infant foods.  Currently, it is sold in the United States as a dietary supplement, and has been given a designation of GRAS (that is, Generally Recognized as Safe) ingredient by the Food and Drug Administration.

Mechanism of Action

Scientific study of L-Theanine has determined that it contains psychoactive properties, meaning that it can cross the blood-brain barrier in order to affect brain function via the central nervous system.

These studies lead to the speculation that L-Theanine has the capability to mimic the functionality of glutamate, a naturally occurring bodily amino acid that assists in the transmission of nerve impulses in the brain.  Additionally, L-Theanine has demonstrated a capacity to increase dopamine levels in the brain, and contains a low affinity for NMDA, AMPA, and kainite receptors.

Potential Benefits of L-Theanine

The research on the mechanical operations of L-Theanine has led scientists to determine that it contains a host of potential benefits related to brain functionality.  Some of these potential benefits include:

  • The ability to reduce mental stress
  • The ability to reduce physical stress
  • Improvement of cognition and cognitive performance
  • Improvement of mood

These benefits tie into L-Theanine’s demonstrated psychoactive properties, as it has been shown through scientific study that it can act on the central nervous system to alter mental cognition, mood, and behavior.  For example, high doses of L-Theanine – that is doses that are higher than the typical dose that is found in a 20 mg cup of black tea – have demonstrated a facility to relax the mind without promoting drowsiness as a side effect.

Another study concluded that a 50 mg dose of L-Theanine caused a greater increase in alpha activity; a type of brain-related activity that plays a vital role in attention.  Other studies have also yielded enhancements relating to cognition and mood when L-Theanine was combined with caffeine.

Medical Interest in L-Theanine

Because of L-Theanine’s ability to improve brain-related function and activity, there has been a keen medical interest that has developed around its potential usage in relation to the treatment of brain-related ailments and maladies.  L-Theanine’s facility to improve brain functionality has led to the theory that it could be a vital component in the treatment of Alzheimer’s disease.

Other studies relating to its positive ability to lower anxiety has led to the notion that it could be an aid in combating schizophrenia or schizoaffective disorder.  Other studies have led to the notion that L-Theanine could be useful in the prevention of ischemic neuronal damage that may occur due to stroke.

Additionally, scientific study on animal test subjects in relation to L-Theanine has led to the determination that it could be used to aid in other aspects not necessarily related to brain functionality.  These include the lowering of lipids within the bloodstream and fighting obesity.

Safety, Dosage, Tolerance, and Potential Side Effects of L-Theanine

L-Theanine has been determined to be safe for human usage in the United States by the FDA – a ruling that is not too surprising, since it is something that occurs in both green tea and black tea.  In terms of therapeutic dosage, it has yet to be determined what the optimal dosage should be.

That said, it should be noted that the studies regarding the positive effects of L-Theanine were typically based on dosages that are far greater than what is found in the average cup of tea.  It also should be stated that there is still questions that relate to L-Theanine and the frequency of usage – specifically, whether or not it can be ingested safely on a daily basis.

In terms of tolerance, research has yet to determine whether or not a significant level in relation to L-Theanine can be built up over time.

These statements have not been evaluated by the FDA.  This product is not intended to diagnose, treat, cure, or prevent any disease.

Conclusion

Because L-Theanine is something that occurs as a natural element to green tea, the potential that relates to its usage as a therapeutic element and as a means to assist in brain functionality is quite high.  While some of its benefits have been noted through scientific study, it would seem that science has only begun to unravel the many ways that L-Theanine can aid people.

    One of my all-time favorites. Induces alpha brain waves thus promoting calm effects. Great to mix with anything GABAergic. Helps with sleep inducing but could act as a mild stimulant if taken with coffeine. Seems to be high purity and I love the price!

    L-Theanine gives my creative process wings to soar

    If you are a creative type L-Theanine is worth your attention. Bloggers, authors and especially adcopy writers should know that…

    L-Theanine is a promoter of Catchyismismism, definition:
    Ad copy that is soaking wet with creative, articulate, and concise eloquent grammatical constructs which will grab your reader\’s attention like a lover.

    As creative types we fantasize about this perfect world where we would sit down in front of our computers to create and inspiration would always strike, we would consistently hit this creative flowstate just and produce brilliant stuff.

    The reality is that it’s a lot more messy than that, sometimes after an hour of laboring away with the empty page, what we have produced is worthy of nothing more than the delete button or the waste bin.

    The secret to being a productive writer is just to do it a lot, get a creative process that works for you, it could be:
    Meditation
    Listening to music
    Doing exercise
    Outlining your writing work with a mindmap
    Drink coffee and listen to reaggaton music (like me)

    Here’s my process…
    I think it’s a pretty good process, I’ve used it to write +170,000 words and hundreds of articles, feel free to steal it!
    Most of my writing is taking quiet uninspiring, dry, scientific papers and cross referencing their data with anecdotal experiences and quantified self type data coming out of the biohacker community and turning them into +2000 word articles that give the data some personality.
    On the first day of working on an article, what I will try to do is skim 3-4 studies and I will find a couple of quotable lines in them, I will copy and paste them into my blank document (with attribution links, obviously).
    Then I will go over to Longecity.org, Bulletproof Exec forum, Amazon reviews and even Reddit and speed read 25-50 different people’s experiences with them. Out of these I will grab a couple of other lines of insightful user experiences with the smart drug or biohacking tool in question.
    Once I’ve immersed myself in the subject matter for 15-30 minutes doing this I will begin to reach conclusions and grasp some of the nuances of the subject matter.
    The creative gears in my head will start to work, I will kind of free associate my thoughts on paper.
    I will frequently run into moments where I need some more data to reference or an anecdote to support a conclusion I’m making, if I don’t have that data immediately on hand I will just add an under strike __, because I don’t want to disrupt my creative flow finding hard information.
    On my second or third day, as I near the end of writing an article I will search Crtl-F for the under strikes __ and I will finish developing these areas of content. A lot of times I just need to track down a few more quotes from studies
    Obviously, I try to stay open minded during this process, if I run into a study that has data contrary to a conclusion I reached earlier or a feature-benefit I try to present pros and the cons, thus allowing the reader to make the conclusions.
    L-Theanine gives this process wings to soar.

    I wrote my science fiction story, a Post Opp’s Devolution, which you can find the first 6 chapters of below, while on L-Theanine.
    I wrote an ebook on text message marketing entitled, 93% Open Rates: Rich Content Mobile Marketing Demystified, while on L-Theanine.

    I used it before the talk I had to do for the Medellin Lifehacker Meetup, I had a couple of small disasters occured. I was expecting to have an assistant, they flaked on me. Then I had reserved the whole space at the venue but there where these two guys sitting right in a table that some students needed to use. Despite these minor disasters, I had next to no stress, I was able to do a presentation of over 2 hours, and it was a pretty good little event. I tried it a couple of times in social settings or before dates and I don’t really feel like it did much for my verbal skills.

    It also absorbs nicely, just dump it in your beverage and it will dissolve into it. Taste is really pleasant actually, it kind of tastes like green tea, which is what you would expect. Umami, proprietary taste family of green tea, which actually comes from L-Theanine.
    It is supposed to improve the bitter tastes, like those of coffee, dark chocolate and grapefruit.
    I insist on drinking such high quality coffee that I really haven’t been able to test this, all the coffee I drink is just really delicious stuff

    L-Theanine is the active ingredient in green tea, which contains caffeine, which is energizing, so you really shouldn’t drink it within several hours of going to bed. L-Theanine itself doesn’t contain any caffeine, so if you like to drink a glass or two of red wine in the evenings and write for several hours and you want to supplement your creativity without screwing up your sleep L-Theanine supplementation is worth considering.

    I like to stack it with other Nootropics that put me into super geek mode, like Modafinil and the Racetams. L-Theanine delivers relaxation without sedation, so it takes the edge off some of these really intense smart drugs. L-Theanine classically gets stacked with caffiene, the two are a great combination, especially for creatives because the caffiene gets you motivated and the L-Theanine gets you inspired.

    Cost Comparison
    Powdered
    $15 50 Grams / $25 100 Grams
    Capsules
    $25 12 Grams 200 mg X 60
    Green Tea
    8 Cups of Green Tea = 200 milligrams

    Each little spoonful of is powdered 350-500 milligrams. All around it’s an excellent value, when I finish with my little 50 Gram bag, I will order the 100 Gram bag – heck I would order a scarface mountain of L-Theanine if I could.
