perfect to get more out of your nights
 April 14, 2014
"This is a great product. You can feel it within an hour after take. It relaxes the body in a very natural way. I used to wake up from time to time feeling very grumpy and low energy. Not anymore. Even if there might be some interruptions within the night, I get more rest during the moments of deep sleep."

Great Product

"I have trouble sleeping. Used this product years ago until it was taken off the market by our government. It's back and better than ever. I use it every night, twenty minutes before I go to bed. I sleep the whole night through. I wouldn't be without it."

About time
 August 2, 2010
"After nearly 20 years of not being able to get L-tryptophan in this country I am delighted and surprised that it is available again. So far I am happy with this product and am sleeping better. I also take a B complex vitamin along with the L-tryptophan because many years my Dr. said it helps aid in the production of serotonin."
