A+

One of the main reasons I started taking L-Theanine was to help manage stress and anxiety, and I've been really impressed with its calming effects. It helps me feel relaxed and centered, without making me feel sleepy or groggy. It's the perfect supplement to take during busy, high-stress days when I need to stay calm and focused.

Excellent!

One of the best supplements for sleep.I take with magnesium glycinate before sleep and I can say that i have a really restful night sleep.And the main ingredient is Suntheanine® that can improves focus, attention, mental clarity and learning performance and improves sleep quality.

De-Stress

I take theanine to deal with general stress. It has a great calming effect but one remains with full alertness and focus. Sun Theanine is a recommended preference. It is very good.
