Life Extension Glutathione Cysteine and C 100 Capsules
Glutathione 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, 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.

Glutathione Cysteine and C 100 Capsules by Life Extension
L-cysteine is a conditionally essential amino acid, one of only three sulfur-containing amino acids, the others being taurine (which can be produced from L-cysteine) and L-methionine (from which L-cysteine can be produced in the body by a multi-step process). 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.

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.
Vitamin 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.

** A note from David and Gail to Cancer Fighters: Just hearing the word, cancer, can instill fear in most of us. However, cancer can be fought and we can win that fight! David has three kinds of cancer. Two of them are stage 4. He fights every day. It is not an easy fight, but the encouragement, prayers and love of family and friends has helped him to continue fighting. If you, or someone close to you, have cancer, remember: "You are stronger than you think, braver than you believe, and loved more than you know."
