Product Overview

Denamarin (S-Adenosylmethionine and silybin) is an easily administered chewable supplement designed to boost your dog’s liver function. This occurs by increasing the liver’s gluthione levels, a powerful antioxidant that improves the liver’s ability to detoxify, metabolize, and regulate cellular activity such as cell death, cell repair, and cell regeneration.
Denamarin chewable tablets supports 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 designed as a liver supplement for dogs.
Denamarin raises the production of antioxidants in the liver, supporting hepatic functions such as metabolization, detoxification, and cell regulation. It has also been found to promote brain health.
The key ingredient in Denamarin is SAMe (S-Adenosylmethionine), which has demonstrated strengthening effects in the liver’s overall function, as well as its ability to conduct cell regulation, repair, and regeneration.
No known side effects
Active Ingredients (pet tablet) Amount 225 mg S-Adenosylmethionine* and 82 mg Silybin-phosphatidylcholine complex (SPC)† * Denamarin Chewable Tablets contain NMXSS75® S-Adenosylmethionine, proprietary veterinary researched specifications. † Providing 24mg of Silybin A + B
Contact your closest emergency pet hospital.
Exclusively for use in dogs and cats.
Sold in 30 ct or 75 ct bottles.
Nutramax Laboratories, Inc
To help support silybin, vitamin E, and zinc levels, Denamarin may be administered alongside Marin Plus for Dogs. If you choose to treat your dog with additional supplements, they should be given twelve hours apart for highest results.

Great product.

My little Pomeranian Princess,has been on this for 7 years.Her doctor said she is good,the medicine is keeping her liver good.

Dawn D Verified Purchase

My dog loves these!

I have been giving my dog the traditional Denamarin pills for 2 years due to her high ALTs. Every morning, an hour before feedings, I had to put one of those big pills down her throat. It was worth it because they are part of her medical plan that is literally saving her life. What a godsend to find the supplement in chewable tablets! Now, every morning, she comes to me for her Denamarin!!! Such a more gentle way for us to begin our day!

3.5. These really should rate 5 stars because my dog's liver enzymes have been stable after taking this in conjunction with fluconazole for over a year. I am very grateful! I deducted one star, though, because they are insanely expensive (there really needs to be a generic) and another half star because, although they are chewable I have to disguise them with peanut butter to get my dog to eat them, which is contrary to the instructions (though my vet says is a common complaint and okay).

Without Allivet supplying the Denamarin for my PixieWinkle baby girl Chihuahua, she wouldn't be nearing her 16th birthday! She has been in liver failure for almost 3 years and by having her Denamarin and every day, she wouldn't still be with me enjoying her life! Totally awesome!

My Chihuahua, PixieWinkle, has been in liver failure for 3 years. Denamarin has kept her alive and I love her and am so thankful for Denamarin!!!

It works! But... it's getting harder and harder to get the pill into her. She detests the taste of the chewable and i have to chop it up and hide it in wet food or peanut butter. It's better than the giant blue tablets that turn my fingers and my dog blue around the mouth during our struggle to put it into the white dog. I wish the makers would get the message that the blue tablet coating is ridiculous and some dogs don't like whatever flavor they are using.

We've been using this product to help our 12 year old Labrador, Sadie. She has kidney disease, and idiopathic (so far) elevated liver enzymes. Her tests have improved since being on Denamarin and these chewable tablets are much easier than administering the non-chewable version. Thanks for making them available.

Our scotty was put on liver medication and almost immediately came down with deadly skin disease - vet gave him 3 months to live - started him on Denamarin and a miracle medicated shampoo and his skin disease virtually was gone within 2 months and a lot of attention! He's like new again, well, almost. Not sure what cured him, but not stopping a good thing!

Mary S Verified Purchase

Sadie was recently diagnosed with liver disease, the Vet has recommended this as the first course of action. She has been taking this now 3 days, there appear to be some positive changes in Sadie's behavior, less water consumption, reduction of 'accidents' and overall a little more chipper. Allivet was fast in their shipping, the items were shipped securely and arrived in excellent condition. Allivet has always been reliable and safe as a choice for my Pet Meds over the last 2.5 years, a go to choice for all of my Pet Med requirements.
