Effective Supplement.

Posted by iHerb Customer on Oct 03, 2017 | Verified Purchase

I must say it really worked for me. During my first bottle, I could easily get into sleep and had really quality sound sleep. After I finished i didn't order and stopped taking. I could feel the difference. Went back to previous times when I had bad quality sleeps where I'll wake up few times in the middle of the night. And had difficulty falling asleep also. Really regretted. Now I start reordering again.

Thanks for your feedback!
