I didn't notice how well this stuff worked until I forgot to take it one day and turned into kind of a space ace. Suntheanine is supposed to be more effective than regular plain L-Theanine. I've tried both and I suppose it is a little better.
Perfect kind of calmness

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

Worth every Penny. I have been suffering from ADHD for a long time now and am using this instead of medication. I just wish there are high dosage capsules for the more serious conditions like mine
Can't live without this product.

This L-theanine is the best I have tried! I have tried several brands and I am convinced this is the purest,highest quality product. I've seen what a 99% pure L-theanine looks like and tastes from another well know company. It is pure white with neutral taste. Many other companies cut there L-theanine with some junk but not Doctor's Best. The calming effects and pleasant energy are much more pronounced with this quality product!
L-Theanine for Anxiety
Posted by ReaCovery on Jan 03, 2016
I'm still experimenting with these, trying to find my optimal dose and when best to take it, but it works great to lower anxiety and calm my nervous system down. I'm trying several brands and this one works fine. I'm recovering from protracted antidepressant withdrawal, and high levels of anxiety and fear have been some of my worst symptoms and this has been one of the few supplements which has really helped. I have to be careful not to take too much or I tend to get a bit apathetic and unmotivated to do much.

After half way finishing the first jar it seems been given some tension release to my teenage daughter and she's going to bed freewillingly with better sleep. Promising product so far!
