It is a building block for glutathione, a tripeptide formed from glycine, L-glutamic acid and L-cysteine that the body produces itself. Taking glutathione or plain L-cysteine directly is less practical, as cysteine is unstable, which is one reason NAC is so widely used in supplements. NAC is not found naturally in food, so a supplement is the usual way to include it, and physically active people often add it to their routine.\u003c\/p\u003e\u003cp\u003eAvailable in a 200g pack.\u003c\/p\u003e\u003cp\u003eFood supplements should not be used as a substitute for a varied, balanced diet and a healthy lifestyle.\u003c\/p\u003e","brand":"OstroVit","offers":[{"title":"200g","offer_id":48432221749436,"sku":"P50329","price":12.91,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0022\/4709\/8438\/files\/image_2026-07-27_6a672d580d7f5.jpg?v=1791715433","url":"https:\/\/www.ivitaminsshop.co.uk\/products\/ostrovit-nac-natural","provider":"IVitamins Shop","version":"1.0","type":"link"}
