{"product_id":"l-citrulline-powder-200-grams","title":"L-Citrulline Powder - 200 grams","description":"What is L-Citrulline? L-Citrulline is an amino acid that plays an important role in nitric oxide metabolism and regulation. In the body, L-Citrulline is converted to L-Arginine to support L-Arginine and nitric oxide levels. Increased production of nitric oxide promotes vascular dilation which improves oxygen and blood circulation throughout the body. Research has shown that L-Citrulline raises plasma L-Arginine, thereby allowing higher protein synthesis and protein content in muscle during exercise.","brand":"Doctor's Best","offers":[{"title":"Default Title","offer_id":55643850080632,"sku":"P30659","price":21.41,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0047\/2055\/8129\/files\/image_2026-03-09_69ae93b734bc5.jpg?v=1788007338","url":"https:\/\/www.libertysupplements.co.uk\/pt\/products\/l-citrulline-powder-200-grams","provider":"Liberty Supplements","version":"1.0","type":"link"}
