Product Information

Help your pet keep a healthy and well functioning liver with Nutramax Denamarin Supplemental Tablets for Dogs and Cats. This nutritional supplement for cats and dogs contains S-Adenosylmethionine (SAMe) and silybin and is made to help protect liver cells, and support the organ with silybin. Chewable and easy to administer, Nutramax Denamarin Supplemental Tablets for Dogs and Cats is recommended by veterianrians and has no know serious side effects.

Nutramax Denamarin Supplemental Tablets for Dogs and Cats Features and Beneftis:

  • Veterianarian recommended
  • Supports healthy liver function
  • Does not raise antioxidant levels
  • Silybin helps digestion and nutrient absorption
  • No known side effects
  • Contains S-Adenosylmethionine (SAMe)

Instructions for Use:

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, Denamarin 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.

Denamarin for Cats and Small Dogs 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.

Administration Guidelines:
For cats and small dogs up to 12 lbs - 1 talbet daily
For medium dogs 13-34 lbs - 1 tablet daily
