Product Summary
  • Daily supplement for liver health
  • Available without a prescription
  • Increases glutathione levels, an important antioxidant that protects your pet’s cells from dangerous toxins


Denosyl is a daily supplement that helps support proper liver function. Support of a compromised liver, regardless of the cause, is essential if function is to be improved. Denosyl has not only been shown to markedly increase glutathione levels in the livers of dogs and cats, but to go far beyond that. Denosyl has been shown to protect liver cells from cell death and may be useful in cell repair and healing. Its main ingredient is S-Adenosylmethionine (SAMe).


Because the tablet must be kept intact to prevent destruction by stomach acid, administration range is based on the nearest whole-tablet. The chart below is provided as a guide for administration. Daily administration may also be calculated based on 20 mg/kg of body weight and rounded to the closest tablet size or combination of sizes.

For optimal absorption, tablets should be given on an empty stomach, at least one hour before feeding, as the presence of food decreases the absorption of S-Adenosylmethionine. For those owners who have difficulty administering tablets to their pets, Denosyl® tablet(s) may be disguised in a small bite of food. Studies have shown that, in many cases, tablets or capsules given as a “dry swallow” do not pass into the stomach in cats but may become lodged in the esophagus. It is recommended for pet owners to administer 3-6 cc of water immediately following any tablet administration to speed passage of the tablet into the stomach.12,13 Denosyl 90 mg tablets are ideal for cats because of their small size. If the pet is to receive more than one tablet daily, the total number of tablets may be divided between morning and evening for ease of administration. For example, a daily administration of three tablets could be divided into two tablets in the morning and one tablet in the evening.
