{"product_id":"proline-lysine","title":"Proline \u0026 Lysine","description":"L-lysine is one of 9 essential amino acids that cannot be made in the body. It is the basic raw material for carnitine synthesis. L-proline can be made in the body, but low-protein\/vegetarian diets may not always promote optimal L-proline production. L-lysine and L-proline amino acids are the precursors of hydroxylysine (HL), and hydroxyproline (HP), two constituents of collagen. Collagen is an essential component of arterial linings. Vitamin C, a strong antioxidant, is also essential for the production of collagen. Hawthorn berry and grape seed extract are potent natural antioxidants due to their high levels of proanthocyanidin. These proanthocyanidin-esters are excellent free radical scavengers.*","brand":"Source Naturals","offers":[{"title":"Tablet \/ 550 mg \/ 60 Tablet","offer_id":54589174612136,"sku":"SN0757","price":12.75,"currency_code":"USD","in_stock":false},{"title":"Tablet \/ 550 mg \/ 120 Tablet","offer_id":41842553520296,"sku":"SN0758","price":23.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0536\/5429\/0600\/files\/021078007579-01_a9aec758-5e31-4373-a481-00f0757b2f7b.png?v=1779635562","url":"https:\/\/www.sourcenaturals.com\/products\/proline-lysine","provider":"SourceNaturals","version":"1.0","type":"link"}
