Best type of theanine

Always make sure to get 'Suntheanine' and not just 'theanine'... the suntheanine is a higher quality and more absorbable form of theanine. The dosage is perfect as well.

Works nicely as a semi-mild sleeping aid for the evenings...

... when you feel stressed or anxious. There are also other good candidate products, and you should try out a few to see which one works best for you (as I did). PS. Be sure to check my profile page for +180 reviews on iHerb products.

Just as it says on the package. Relaxation without drowsiness. Perfect if you feel too stressed and need to get things done.

Great for social anxiety and irritability

Theanine helps me to cope with the anxiety I experience whenever I am faced with a social situation. It makes me calm, happy and more sociable. It's also good at calming my irritability during those times of month, or whenever I take too much caffeine. I used to take the Source Naturals brand but prefer this as it contains less Theanine (too much can make me a bit spacey).

L-Theanine

Works quite well for mild anxiety and stress. I take L-Theanine occasionally, usually after lunch at work and it seems to help me focus better.
