L-Tryptophan by Doctor's Best features Ajinomoto TryptoPure® tryptophan. This essential amino acid is able to cross the blood-brain barrier. L-tryptophan is altered by enzymes to first form the intermediate amino acid 5-HTP and then serotonin. It is also the metabolic precursor to melatonin and to the B vitamin niacin. Supplementing the diet with Doctor's Best L-Tryptophan can improve sleep and enhance mood, and may also be beneficial in reducing carbohydrate cravings.

Rated 5 out of 5 by 4 reviewers.
Rated 5 out of 5 by This helps me This product helps me. When I stop taking it I feel it. February 29, 2016
Rated 5 out of 5 by 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. January 21, 2016
Rated 5 out of 5 by 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.

Rated 5 out of 5 by Sleep like a baby! I find this a great value for Tryptophan! I just can't sleep without it. Before I tried this I would wake every night after sleeping a few hours, and lay there for hours before I could go back to sleep. I take two nightly after dinner, at least an hour before bed. Under stressful situations when I might have even more trouble sleeping I will take another right before bed. I sleep like a baby! Thank goodness we can get Tryptophan again! March 16, 2012
