Nervous System support
The essential amino acid L-tryptophan helps support relaxation, restful sleep and positive moods. It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress responses and sleep and wake cycles. L-tryptophan also supports immune functions because it is the body’s precursor to the kynurenines that regulate immunity. If needed, it converts to niacin in the body, which supports circulation, a healthy nervous system, the metabolism of food and the production of hydrochloric acid for the digestive system.
