XYMOGEN, Liver Protect™ 60 Capsules

Liver Protect^™ contains the amino acid N-acetyl-L-cysteine, a key component of glutathione—a tripeptide that plays a significant role in detoxification and antioxidant support. Liver Protect also contains a combination of alpha-lipoic acid, milk thistle extract, and selenium for support of antioxidant activity, regeneration of other antioxidants, and promotion of healthy immune function.*

• Supports Healthy Liver Function*
• Supports Cytokine Balance*
• Supports Glutathione Production*
• May Protect Liver Tissue*

The liver is the body’s major metabolic organ. It processes, packages, stores, and ships out carbohydrates, fats, proteins, and micronutrients. It is responsible for the breakdown and elimination of alcohol, toxins, hormones, and medications, as well as for the synthesis of vital proteins, such as albumin, prealbumin, and clotting factors. It may be stated that the health of the body depends on the health of the liver. Research suggests that providing targeted nutrition supplementation may help support liver function and health.*[1]

N-Acetyl-Cysteine (NAC) An acetylated derivative of the sulfur-containing amino acid L-cysteine, NAC promotes the synthesis of glutathione—a tripeptide that is active in detoxification and antioxidant systems. Glutathione also supports a healthy defense against hepatotoxic environmental pollutants, gamma-radiation, and other potential toxins.*[1,2]

Alpha-Lipoic Acid Sometimes referred to as thioctic acid, alpha-lipoic acid is both water- and fat-soluble. It supports glutathione, helps regenerate antioxidant vitamins C and E, helps maintain the ratio of reduced to oxidized CoQ10 in the mitochondria, and helps support healthy levels of nitric oxide in the liver and kidney.[3] The redox couple of lipoic acid and dihydrolipoic stabilizes NF-kappaB transcription and may help support healthy immune functions in the body.*[4,5]

Milk Thistle Seed Extract Silymarin, the active component in milk thistle, has a history of use in promoting liver health. It supports antioxidant activity, neutralizes toxins, and also may protect hepatocytes’ genetic material. Like alpha-lipoic acid, silymarin supports the production of cellular glutathione. Its actions in the liver include maintaining normal levels of fat peroxidation and fibrous tissue formation; supporting a healthy immune response and the natural response to inflammation; and promoting protein synthesis and normal regeneration of liver tissue.[6] A randomized placebo-controlled study of 103 individuals suggested that silymarin yielded statistically positive results and was well tolerated.*[7]

Selenium (as selenomethionine) An important coenzyme for the glutathione peroxidase detoxification system, selenium also appears to support the endogenous antioxidant defenses of hepatocytes by upregulating their manganese superoxide dismutase (MnSOD) expression. At the same time, selenium appears to support healthy cytokine balance by affecting interleukin-6 (IL-6) transcription in Kupffer cells (liver-based macrophages).[8] Kupffer cells play a crucial role in maintaining normal structure and function in the liver. Supporting their function and the body’s normal inflammatory response in turn supports liver health overall.*[9]

Upon studying targeted nutrition support for liver health, researchers combined alpha-lipoic acid, silymarin, and selenium to obtain a balanced and low-cost approach to liver support.[10] These three ingredients plus NAC are all present in Liver Protect™ to support liver health, antioxidant activity, and the body’s natural immune defenses.*
