Because of the toxic effects of food, water, and the environment, the liver can be a very busy organ, for humans as well as companion animals. Thorne Research Hepagen-C combines the beneficial liver herbs milk thistle and curcumin with antioxidants and important nutrients for phase I and II liver detoxification.

  • Thorne Research Hepagen-C small animal hepatic support:
  • Protects hepatic cells
  • Promotes phase I and II detoxification
  • Supports healthy glutathione levels

Pyridoxal 5'-phosphate acts as a cofactor for enzymes, catalyzes reactions with amino acids, and aids in the synthesis of nonessential amino acids. In this formula, the active form of vitamin B6, pyridoxal 5'-phosphate, is provided because healthy liver function is necessary of activation of vitamin B6. Vitamin B12 is required for proper digestion and absorption of food. It is also utilized in amino acid digestion as well as carbohydrate and fat metabolism.

Dimethylglycine (DMG) is a derivative of glycine, the simplest amino acid. It is a building block for many important substances, including methionine and choline. Choline citrate is a lipotropic factor essential to the lipid layer of cell membranes. It helps regulate the gallbladder and is used extensively in the liver to move fats in and out of the cells. It is required for formation of the hepatic cell membrane component phosphatidylcholine and the neurotransmitter acetylcholine. Methionine is an essential sulfur-containing amino acid necessary for phase II detoxification. It helps metabolize fats and is a precursor to cysteine and taurine synthesis. It can be converted to cysteine, a component of glutathione, an important endogenous antioxidant.

N-acetylcysteine (NAC) is composed of the amino acid cysteine and a sulfhydryl group, enabling it to interact with disulfide bonds. NAC serves as a nutritional precursor for the synthesis of glutathione. Reduced glutathione is an important endogenous antioxidant, essential for liver detoxification. alpha-Lipoic acid is a powerful antioxidant that enhances the antioxidant effects of vitamins C and E and glutathione. alpha-Lipoic acid induces a substantial increase in cellular reduced glutathione by enabling the key enzyme of glutathione synthesis, gamma-glutamylcysteine synthetase. It is an antioxidant in both fat- and water-soluble tissues and in both its reduced and oxidized forms.

Silybum marianum (milk thistle) contains several potent flavolignans, including three structural isomers, silybin, silydianin, and silychristin, collectively referred to as silymarin. The antioxidant activity of silymarin appears to stabilize hepatocyte membranes, neutralize free radicals, and maintain liver glutathione levels. Curcuma longa has been used traditionally as a hepatoprotectant and cholegogue in both Chinese and Ayurvedic medicine. Its beneficial effects may be due to the fact that curcumin is a potent antioxidant and it helps maintain a normal inflammatory response.

    Comments about Thorne Research Hepagen-C:

    Gabe, my 15 1/2 year old Golden/Sheltie, has had his gall bladder removed, and has a heart condition and some arthritis. I've been giving him a plethora of meds for these conditions and have been frustrated feeling that he wasn't having the quality of life I'd hoped for.
    His veterinary acupuncturist suggested that some of the meds could be causing stomach upset and should be removed.
    His veterinarian was very open and researched what especially might be a good substitute for the med we were giving him for arthritis. He came up with Hepagen-C.
    I am very happy with Gabe's progress since adding Hepagen-C to his regimen. His arthritis doesn't seem to bother him as much, his walks are longer and his spirit is much better.

      I used this product when it was found my just rescued dog had elevated liver enzymes on her initial blood test. The formulation is fantastic! And thorne already has a great reputation in the human health profession so I don't have to worry about the quality of ingredients they use.
