L-theanine is considered a non-dietary amino acid, but it can still provide a wide range of potential benefits when supplemented. Read ahead to learn more about this nootropic and how you may use it to enhance cognition.
L-Theanine Powder is derived from Camellia sinensis--the tea plant. Black, green, and white teas all come from the Camellia sinensis plant and also provide the compound. L-Theanine is an amino acid, but it isn’t an essential amino acid or one of the more common nonessential amino acids that you might be more familiar with.
Although tea has been consumed for centuries and touted for its benefits for just as long, it was only in 1949 that L-Theanine was discovered as a constituent in green tea. L-Theanine has been used in various food and drink items in Japan since the 1960s. Perhaps surprisingly, L-Theanine can provide an umami (savory) flavor.
L-theanine has been shown to potentiate GABA, or gamma-aminobutyric acid, a naturally occurring amino acid.
L-theanine may also encourage the release of several other neurotransmitters. These neurotransmitters can have a wide range of effects on cognitive processes, tapping into feelings of reward, pleasure, and motivation. Theanine may also promote more restful sleep cycles.
Furthermore, L-theanine may increase your brain’s alpha waves, resulting in increased mental alertness and improved focus and clarity. This may lead to greater productivity aimed at increasing motivation. Some studies have even found that increasing alpha brain waves may encourage creative thinking.
L-Theanine is a naturally derived supplement that has been given GRAS status by the United States FDA, meaning that the compound is generally recognized as safe.
As a dietary supplement, take 100mg of L-Theanine 1-2 times daily.
Nootropics Depot offers 125g or 500g jars of high quality L-Theanine powder. Nootropics Depot's L-Theanine has been lab-tested and verified for both product purity and identity. L-Theanine has been granted GRAS (generally recognized as safe) status in the United States.

powder worked for me, doesn’t taste or smell bad. I was happy that it was properly sealed with shrink wrap and with a seal under the lid. would recommend Unknown on 14th Sep 2018
Works as expected and tastes much cleaner than a BulkSupplements batch I tried. Will only order theanine from here now. Unknown on 27th Jun 2018

Theanine calms me, gives me more focus, reduces some stress. James W. Doty on 30th May 2018
It feels like I kinda imagined it working for a while so I took it a lot, but I haven't missed it since. I'm pretty sure though that it has helped me to bring down like caffeine jitterness or something of that sort. Ghostsforfriends on 25th May 2018
This is a high quality great product promotes sleep and relaxation recommend it to all my friends Nelson on 23rd May 2018
This is a must-have if you take caffeine! I use a lot of caffeine at work and this mitigates all the jitters and restlessness when I'm at my desk. I also take some before I workout to keep me focused and calm. I have mild stress and this is great when in public/ talking to people! Unknown on 17th Apr 2018
