Source Naturals Source Naturals, L-Tryptophan, 120 Tablets

Product information Overview Dietary SupplementMood, Relaxation, SleepNon-GMO ValidatedSuitable For VegetariansThe 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. Suggested use 1 tablet three times daily, between meals and preferably with fruit juice. To support restful sleep, take 3 tablets before bed.
