It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response and sleep\/wake cycles. 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.\u003c\/p\u003e","brand":"Total Nutrition","offers":[{"title":"Default Title","offer_id":52065364771108,"sku":null,"price":20.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0882\/8197\/3028\/files\/40.avif?v=1772490039","url":"https:\/\/totalnutritionusa.com\/products\/source-naturals-l-tryptophan-500-mg-60-capsules","provider":"Total Nutrition ","version":"1.0","type":"link"}
