L-Tryptophan 5 5 5 6
How to get a good night's sleep Works great with no lingering effects the next morning. I use nightly. September 1, 2014
helpful at bedtime This helps me fall asleep quicker. That is what I wanted it for and it is helpful for that. For me I need to take it maybe an hour or a little longer before bed for the effect to be noticeable. Also I found I had to adjust the amount of capsules until I found an effective amount. These aren't cheap but I can honestly say for me they are helpful. July 11, 2013
It Works My husband and I have a lot of trouble sleeping and this product has made a big difference for us. When he awakes in the middle of the night and can't return to sleep, he takes 500 mg. and fall back to sleep within 30 minutes. It makes me fall asleep at bedtime and helps to keep me asleep.
