Denosyl SD4 is a brand new nutritional supplement designed to protect and detoxify the liver. It works by increasing levels of glutathione in the body. Glutathione is an antioxidant and detoxifying agent that is needed to maintain and protect the liver and other organs. Glutathione is dramatically decreased in dogs and cats suffering from liver disease. Denosyl SD4 helps rebuild this necessary compound. It also protects the cells of the body and may help reduce pain and inflammation. SD4 is recommended for dogs and cats suffering from hepatitis, pancreatitis, inflammatory bowel disease, and fatty liver disease, as well as those animals taking medications that could harm the liver. Tablets are enteric coated and available in 90 mg, 225 mg and 425 mg. The tablets are packaged in boxes of 30 tablets. Dosage: Cats and dogs up to 12 lbs., one 90-mg tablet per day. Dogs 13-24 lbs., two 90-mg tablets per day. Dogs 25-35 lbs., one 225-mg tablet per day; 35-65 lbs., two 225-mg tablets per day; over 65 lbs., 3 tablets per day. Dosage may be given every other day after the pet is stabilized.
