This is my review of L-Theanine after taking it for 7 Days:
After doing a lot of research myself on all different types of Nootropics (Cognitive Enhancers) I decided to try the most basic Nootropic that comes to mind and certainly the most efficacious and inexpensive: L-Theanine.
It is a naturally occurring amino acid found in Green Tea and contributes to feelings of calmness by increasing GABA release in the brain. It's totally safe to use everyday even in high doses reported by many case studies. The many benefits reported of L-Theanine is that it helps with: stress, anxiety, mood, focus, depression and some ADHD symptoms.
Dosage Information: 200-400mg L-Theanine daily, taken 1 or 2 times a day.
