Product Description

L-Glutathione, L-Cysteine &, C 750 mg • 100 capsules Item Catalog Number: 113 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, one of the body's most important natural detoxifiers. N-acetyl-cysteine is the acetylated form of L-cysteine, which is more efficiently absorbed and used. Glutathione (gamma-L-glutamyl-L-cysteinyl-glycine) is a peptide (short protein)-like 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, L-cysteine, and N-acetyl-cysteine in reduced form so that they can continue to provide free radical quenching effects. Even though many published studies show that garlic, selenium, alpha-lipoic acid, L-cysteine, and N-acetyl-cysteine can boost cellular glutathione levels, people wishing to maintain optimal health may benefit from taking high doses of glutathione.* Supplement Facts Serving Size 1 Capsule (750 mg) Servings Per Container 100 Amount Per Serving L-glutathione (reduced) 50 mg L-cysteine HCL 200 mg Ascorbic acid (vitamin C) 500 mg Other ingredients: rice flour, magnesium stearate, gelatin, and water.

1.0 out of 5 stars Beware of product!!, July 15, 2009

A Kid's Review

This review is from: L-Glutathione, L-Cysteine & C, 750 mg, 100 caps (Health and Beauty)

Having just received the product, I read the label, which says

Vitamin C 500 mg

L-glutathione 50 mg

L-Cysteine 200 mg

If glutathione is what you're after, you're pretty much getting an expensive vit. C pill.

Did not contain enough L-Glutathione. Only 50 mg. Perhaps, just not enough pep in their peptides.
