Mental clarity boost
The Japanese have discovered a unique agent that stimulates mental performance - L-theanine from green tea. It activates brain function without causing nervous excitability, promoting calmness and clarity of mind while reducing stress-induced pressure. This has been a revelation for me! After a month of use, my mood and endurance have significantly improved. I take it twice daily, and it causes no discomfort.

Cognitive performance boost
Theanine, an amino acid found in green tea, positively impacts brain metabolism. It promotes relaxation without drowsiness while maintaining concentration, increasing alpha wave production and protecting the brain against glutamate toxicity. I typically take it on an empty stomach, either in the morning or evening for better sleep. Good dosage!

Stress relief noted
It is not surprising, but it works – it alleviates stress without diminishing brain activity. You’re never left feeling like a vegetable, just a cheerful and professional cucumber. Every problem no longer feels like the end of the world, which is precisely what I required. I will purchase more, as GABA did not have this effect.
