Rated 5 out of 5 by from Really Helps You Relax & Sleep Doctor's Best L-Tryptophan is the best product of this kind that I've tried so far. It really helps me to relax my brain so that I can drift off to sleep. And I like that the dosage is only one capsule.

Rated 5 out of 5 by from LOVE L-Tryptophan! Can't rave enough about this product. Not only did it help my mood on a day to day basis, it helps me sleep soundly at night. I've never slept as soundly as I do now. I take 2 tablets before bed and highly recommend it to anybody that wakes up often or doesn't feel rested in the morning. It works and has given me a more positive daily outlook.

Rated 5 out of 5 by from Best L-tryptophan Excellent product. I was looking for L-Tryptophan without dairy, this one fit the bill. It works great for getting to sleep. Wish they made it in a pill form, as the capsule has a tendency to float up to the top of the stomach, pop open, and get into my esophagus, but I try to stay sitting up for a while, or take 30 min before bed time.
