Best 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.

Best L-Tryptophan 5 5 1 1
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
