L-Tryptophan

Benefits
The essential amino acid L-tryptophan helps support relaxation, restful sleep, and positive mood. It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response and the sleep-wake cycle. It also supports immune functions and can be converted to vitamin B-3, necessary for many bodily processes. Source Naturals® L-Tryptophan is extremely pure and is regularly tested to ensure the highest standards of quality.*

Product Benefits

L-tryptophan supports the immune response because it is the body’s precursor to the kynurenines that regulate immunity. If needed, L-tryptophan converts to vitamin B-3 in the body, which supports circulation, a healthy nervous system, the metabolism of food, and the production of hydrochloric acid for the digestive system.*
