Great product, a bit on the pricey side

Posted by Reviewer3017527 on Jun 09, 2013

I love theanine to balance out the edginess from coffee, and this product never disappoints. Jarrow Formulas is a top brand, so the price is right in line with the quality.

Seems to reduce anxiety..

Posted by Reviewer2080411 on Dec 31, 2009

I've been having these for a while now. Wouldn't say that relaxing effect is remarkable, but seems to reduce anxiety noticeably. For a product without side effects, I'd rate at least adequate result and I'm very happy with that.

Effective

Posted by Reviewer2597271 on Sep 20, 2009

For non-drowsiness anti-anxiety it is effective although multiple capsules may be sometimes needed. Recommended (also doctor recommended). Combined with valerian extract (not just root) which is excellent in giving quick sleep, it extends a longer and deeper sleep.
