For Relaxation, Positive Mood & Sleep
L-tryptophan is an essential amino acid and hence cannot be synthesized by the body, but must be obtained from food or supplements. Because L-tryptophan is converted to serotonin (5-hydroxytryptamine) and melatonin in the body, it plays an important role in promoting relaxation, restful sleep, and a positive mood.* L-tryptophan may also help in reducing carbohydrate cravings.* A building block for proteins, hormones, and neurotransmitters that affect mood and sleep.
