Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Rated 5 out of 5 by 3 reviewers.
Rated 5 out of 5 by The combination of ingredients are wonderful! I also use(d) the ingredients separately but there is a difference then. I take 2 before sleep with a little bit of sleep juice (Here is a bit of doxylamine and herbs). I will buy this product again and also with the combination of Relora! July 24, 2014
Rated 5 out of 5 by Good product I take this together with Melatonin, and within a short time I get sleepy. It still doesn't help me sleep through the night, but perhaps I need some more time to see how it works. December 16, 2013
Rated 5 out of 5 by easy I started taking Gaba and needed to add Theanine this product was the right dosage of both that I was looking for in one pill. August 26, 2013
