  • Can improve mood 
  • Shown to reduce anxiety 
  • Can play a role in increasing natural GABA levels 

L-Theanine is a naturally occurring amino acid, commonly found in tea (green tea specifically). It does not contain any caffeine itself, however it is thought to be the ingredient in green tea responsible for providing the calming effects associated with its use.

L-Theanine has shown to improve mood, reduce physical and mental stress and as well as improve cognition. It reportedly does so without reducing alertness or promoting drowsiness.

Structurally, it is related to glutamine and glutamate, but it doesn't quite function in the same way.

Rather than taking GABA, which arguably doesn't cross the blood-brain barrier all too well, L-Theanine works by increasing GABA levels in the brain naturally. GABA is a neurotransmitter responsible for regulating (inhibiting, in many cases) the excitability of neurons in the body, reducing insomnia and general restlessness in the process. Furthermore, theanine also increases levels of dopamine, which along with GABA helps provide the calming and mood-boosting effects L-Theanine possesses.

We find that for improving focus and cognition, it performs well in a synergistic manner with caffeine. L-Theanine also helps in reducing anxiety and getting a good sleep.

Best L-Theanine period.
I have tried a bunch of different L-Theanine powders from different manufacturers. This is hands down the highest quality/purity and it is decently priced. No additives, just pure L-Theanine with a great effect. This the 11th time that i purchased this one and i will continue to do so whenever i run out. Mindnutrition products are as always pharmaceutical grade quality, regardless what you purchase from them.

Antihistamine & good combo with coffee
I take this together with coffee and love how it takes the edge off, helps me focus. I primarily started taking this as an antihistamine but now I appreciate all the other benefits that come with it.

Third order
This is the third time i have ordered so far and i will 100% continue to do so in the future. I have tested different products such as Bacopa Synapsa, Uridine Monophosphate, ALCAR and so on. They were all pharmaceutical grade products. The L-Theanine is the lowest pricest, yet highest quality i have found so far. It provides great effects for me and the packaging is really good (it comes in a plastic container and not a cheap bag like so many others). 100% recommended
