Helps with sleep Helps me sleep better. Makes me feel calm if taken during the day in betwen meals. November 15, 2010
Helps me sleep I take this with melatonin (10mg), L-Theanine (100mg), and Lemon Balm, Passion Flower, Scullcap Complex (2 capsules). This combination helps me get to sleep and wake refreshed in the morning. November 5, 2010
I love this product !! I now get great nights sleep. I am not groggy or tired the next day. Woo Hoo !!! April 16, 2010
Best sleep ever I normally would have a very difficult time getting to sleep but when I take this in combination with 5-htp I sleep so much more comfortably. The key is to take it with 5-htp, because one of these two products by themselves do not do much for me but together they work magic. I also keep one capsule next to me at night in case I wake up a few hours too early and have trouble going back to sleep. I take one and in 30 minutes I'm back asleep. But this product doesn't make me tired, it only allows me to sleep better. I don't wake up croggy and tired, and I can take it during the day if I want to relax without feeling sleepy. March 14, 2010
Great Product I found this product to be exactly what I wanted. It is an excellent price, and seems to be of excellent quality. August 8, 2009
