In addition, research has shown the administration of Denamarin coated tablets to be safe for dogs. Denamarin Liver Health Supplements are brought to you by Nutramax Laboratories Veterinary Sciences, the #1 veterinarian recommended supplement company.

Denamarin tablets support liver health and helps cell repair and regeneration by protecting the liver cells from cell death caused by liver damage. Denamarin may also be used in other areas of tissue oxidant injury caused by certain toxins or drugs.
Denamarin is intended for use in cats and dogs.
Denamarin:
  • Raises antioxidant levels to support liver function
  • Helps to support the health of the brain
  • Does not have any side effects that are known
  • Aids in the protection of hepatic cells from death and toxins
  • In cats, S-Adenosylmethionine has a positive impact on the flow of bile
Denamarin contains an SAMe knowns as S-Adenosylmethionine which can aid in the protection of cell death and liver cells; it may help work with the regeneration and repair of cells.
No known side effects
S-Adenosylmethionine, Silybin A+B
Contact your closest emergency pet hospital.
Denamarin should only be used to treat cats and dogs.
Denamarin is available in three different sizes; for Small dogs & Cats, Medium dogs & Large Dogs
Nutramax Laboratories, Inc
For animals in need of supplementation of zinc, vitamin E benefits, and additional silybin levels, you can use Denamarin alongside Thera-bites. For best response, administer both products 12 hours apart.
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.
 
Denamarin For Cats & Small Dogs
Pet Weight Dosage
Dogs/Cats: Up to 12 lbs 1 tablet
Contains 90mg of S-Adenosylmethionine & 9mg of silybin A+B.
 
Up to 55 kg
1 tablet
 
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.
Denamarin for Cats and Small Dogs up to 12 lbs:
Active Ingredients (per tablet) Amount
S-Adenosylmethionine........................90 mg

My dog's live numbers were wonky, so my vet recommended we try this. Her numbers haven't changed, but it has also been 3 years and she's 14 years old. She doesn't seem her age at all. So worth it.

My boy Lipton’s liver enzymes were to high to continue his chemo. His oncologist told me about Denamarin and how safe it is to give him. That was almost 2 years ago now and his liver enzymes are down and he is able to take his chemo.

Shirlene J Verified Purchase

After my dog's vet prescribed this liver med I was surprised as to the high cost. Since I live on a fixed income. After researching online I found that Allivet had the cheapest price along with monthly autoship and no shipping costs. From the very beginning the customer service has been great. Product arrives safe and sound. And the price is the best! I have no complaints.

Better price than buying from our vet. Arrives quickly and love the autoship. For some reason, my dog doesn’t like these and always tries to spit them out, even if I hide it in a piece of ham or something delicious. She never did that with the ones I would get from my vet. The price is worth having to find sneaky ways for her to swallow it.

Kevin R Verified Purchase

Excellent, I noticed some Pep in my dog’s step. She just started needing this medication and the chewable pills are too hard for my smaller dog to eat even with the capsules pill pockets. It is easier to have her eat just 2 pill pockets rather than 4 of the edible. She is paranoid of pills in her food. 🤢

Our dog,Darby, has liver disease. She must be on Denamarin forever. I signed up on the auto delivery plan. It's been great. Also , I found All over to be the cheapest around! Great company.
