great product as sleep aid esp in combination with valerian and melatonin

Posted by iHerb Customer on February 7 2018 | Verified Purchase

Honestly no different from other L-Theanine products I have used, but have long used a combination of L-Theanine, valerian, & melatonin at night for easy falling asleep (after a life-time of insomnia)!

Thanks for your feedback!

Very good quality, trustworthy brand.

Posted by iHerb Customer on January 19 2018 | Verified Purchase

Not all L-theanines are created equal, in my opinion. This one does exactly what I need it to do.

Thanks for your feedback!
