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 regularly tested to ensure the highest standards of quality.\u003c\/p\u003e","brand":"Source Naturals","offers":[{"title":"Default Title","offer_id":54536991637817,"sku":"31247","price":5.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1015\/3908\/6649\/files\/d8be5e81c6257ace3b6aa85a2cd60f05.webp?v=1790239564","url":"https:\/\/www.lifeextensionus.it.com\/products\/l-tryptophan-500-mg-60-capsules-source-naturals-31247","provider":"lifeextensionus.it.com","version":"1.0","type":"link"}
