N-Acetyl Cysteine Supports the transport of the very fragile and 'rate limiting' amino acid, L-cysteine through the digestive tract for the production of glutathione and is one of the core ingredients in MaxGXL together with L-glutamine, another amino acid glutathione precursor. In addition, other network antioxidants such as vitamin C and alpha lipoic acid, as well as the dietary flavonoid, quercetin have been added to provide complementary antioxidant support.

Cordyceps preserve glutathione based on its known anti-inflammatory properties. Inflammation produces free radicals and other reactive oxygen species that damage cellular components unless they are neutralized by antioxidants such as glutathione. This anti-inflammatory action of cordyceps helps to minimize the use of available glutathione, thus freeing it to perform other important functions within the body.

N-Acetyl-D-glucosamine supports the gastrointestinal absorption of amino acids. It is included in the formula to promote the absorption of N-acetyl Cysteine and glutamine.

Glutamine is converted in the body to Glutamic acid, one of the three amino acid building blocks for the synthesis of glutathione.

Milk Thistle (silymarin) is a powerful antioxidant used to support a healthy liver by removing harmful toxins and heavy metals that are stored in the liver.
