It plays 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.\u003c\/p\u003e","brand":"Source Naturals","offers":[{"title":"Default Title","offer_id":54536991605049,"sku":"31002","price":9.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1015\/3908\/6649\/files\/4de8fd99a65f4493eb22246b7576ffd9.webp?v=1790239563","url":"https:\/\/www.lifeextensionus.it.com\/products\/l-tryptophan-500-mg-120-tablets-source-naturals-31002","provider":"lifeextensionus.it.com","version":"1.0","type":"link"}
