An essential amino acid, L-tryptophan is important in human nutrition for the synthesis of melatonin and serotonin, hormones regulating mood and stress response. L-Tryptophan helps support relaxation, sleep, positive mood and immune function. As an essential amino acid, it is not synthesized by the body and must be obtained from the diet. NOW L-Tryptophan Powder is pharmaceutically pure--every lot is tested to be free of Peak E and microbial contamination.

Rated 5 out of 5 by from Works well I take this in the middle of the night to help me fall back into lala land. I use about 1/2 t of this and about 1t of Swanson inositol powder.. Before bed I mix them in a small container. When I wake up in the middle of the night I dump them directly into the gullet and chase with water.
