Helps my anxiety a lot
Really great quality. I find it working better than the last bend I used. I take one at night and one again in the morning. Along with my other meditations it helps my anxiety a lot!

Subtle relaxation
A supplement for relaxation is hard to find. I have used this one in other brands and can't say if I noticed much change in my mood. I now take this brand at night time to help settle down. I can say while the effect is subtle, it does reduce anxiousness and I have been able to sleep through the nights better. I think it is a bit pricey over other brands, but this one actually works. Reordering.

Wonderful supplement
My son has been taking these for about a year and we have seen a huge difference. His focus has really improved. Really great natural solution for focus issues.

A must for any stressed out mom
This stuff helps me so much. Benefits: much higher threshold for stress, gives the feeling of being able to ENJOY the present moment without letting my stress squash my joy. Inconveniences roll off my back. As a stay at home mom of two toddlers, I highly recommend this brand of l-theanine.

Relaxes
They help take the edge off when I'm feeling stressful, and help with sleep -- but not as much as I would like.
