l-Tryptophan


Mood, Relaxation, Sleep


The essential 
amino acid l-tryptophan helps support relaxation, restful sleep, 
and feeling better. It plays a part in the synthesis of both 
melatonin and serotonin, hormones involved with mood and stress 
response. l-Tryptophan also supports immune functions because it 
is the body's precursor to the kynurenines that regulate 
immunity. If needed, l-tryptophan 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. Source Naturals l-TRYPTOPHAN is extremely 
pure and is regularly tested to ensure the highest standards of 
quality
