Cysteine plays a role in the sulfation cycle, acting as a sulfur donor in phase II detoxification and as a methyl donor in the conversion of homocysteine to methionine. Cysteine also helps synthesize glutathione, the body's most important intracellular antioxidant and a vital detoxifier.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eGlutathione (L-gamma-glutamyl-L-cysteinyl-glycine) is a peptide molecule synthesized in the body from the three amino acids L-glutamic acid, L-cysteine and glycine. Glutathione is one of the body's most important and powerful antioxidants,8 helping to detoxify xenobiotics. A major function of vitamin C is to keep glutathione in its reduced form so that it can continue to provide free radical-quenching effects.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eVitamin C, or ascorbic acid, is a white, crystalline, water-soluble substance found in citrus fruits. As an antioxidant, vitamin C scavenges free radicals in the body and protects tissues from oxidative stress. Vitamin C also promotes the absorption of iron, while inhibiting its oxidation. Vitamin C is a vital cofactor to the formation of collagen, the connective tissue that supports arterial walls, skin, bones, and teeth.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003eSold by Superfood Market since December 2025\u003cbr\u003e\u003c\/p\u003e","brand":"Life Extension","offers":[{"title":"1 x 100 caps","offer_id":56343666360697,"sku":"DAAXI","price":19.22,"currency_code":"GBP","in_stock":false},{"title":"2 x 100 caps","offer_id":56475382284665,"sku":"DAAXI\/2.00\/","price":37.68,"currency_code":"GBP","in_stock":false},{"title":"4 x 100 caps","offer_id":56475382317433,"sku":"DAAXI\/4.00\/","price":74.62,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0863\/6984\/files\/91d2d4f8-21e4-40fe-918d-0630bbab2a68.jpg?v=1765443142","url":"https:\/\/superfood-market.com\/products\/life-extension-glutathione-cysteine-c-100-caps","provider":"Superfood Market","version":"1.0","type":"link"}
