Nutramax Denamarin Chewable Tablets Dog Supplement

When liver function is compromised, the exact cause can often be difficult to determine. Supporting the liver, regardless of the cause, is essential to keep it working properly. Administering SAMe (S-Adenosylmethionine), which is found in Denamarin, has been shown to markedly increase liver levels of glutathione, an important compound for liver health formed when SAMe is metabolized. The SAMe in Denamarin has also been shown to help protect liver cells from cell death and may help cell repair and regeneration. Denamarin also helps support your dog's liver through the administration of silybin. Silybin is an active part of an extract from milk thistle, known as silymarin, and has been shown to support liver function by helping maintain a healthy oxidative balance. Denamarin Chewable Tablets allow dogs to receive SAMe and silybin in a tasty treat, eliminating the need to "pill" your dog daily. Additionally, the chewable tablets allow for quicker uptake of the SAMe and less variability between dogs when compared to enteric-coated tablets.
While best known for supporting the liver in dogs, Denamarin also has a place in supporting brain health. Denamarin provides SAMe in a stabilized form to help with brain health and act as a neuroprotector. Denamarin also provides a bioavailable form of silybin which supports oxidative balance.

Maintaining Liver Health
Nutramax offers three options for liver support—Denosyl, Denamarin and Marin Plus. SAMe, the active ingredient in both Denosyl and Denamarin, has been shown to help protect liver cells, and may help repair and regenerate them. Aside from keeping the liver healthy, SAMe offers support for cognitive function. Denamarin also contains Silybin to maintain a healthy oxidative balance in this important organ. In Marin Plus, five key ingredients go to work to maintain liver function, including Silybin, vitamin E, zinc, medium chain triglyceride and curcumin extract. Marin Plus provides antioxidants and an energy source for the liver and helps it to absorb nutrients from your dog’s food.
Restoring Balance With Proviable
Whether your pup has a temporary case of upset stomach from travel or boarding stress, antibiotics, trying a new food or just having a sensitive system, Proviable helps put things back in balance.

Nutramax Proviable Kits for short-term support: Each comes with Proviable-KP paste with probiotics, prebiotics and stool-firming ingredients, plus Proviable-DC capsules that provide continued intestinal support.

Baby food helps w/fussy dog
By ScottieParent on Feb 26, 2021
We need to give this to our Scottie with liver issues. She would not eat them even though they are chewable. Our vet recommended crushing the tablet, very easy to do with spoon and ramekin, and mixing in about 2 teaspoons of Gerber baby food. Use just enough to combine crushed tablet. And the baby food should be Gerber Sitter 2nd Foods without garlic in one of the meat varieties, chicken, ham, beef, etc. Our Scottie loves it and licks it right up. Giving such a small amount of baby food does not upset her stomach even though product says to give on empty stomach.

Easy Peasy
By EasyPeasy on Feb 22, 2021
Easy Peasy and No More Smurf blue fingers! My dog loves this chewable tablets and thinks they are a treat in morning. I initially started with the Denamarin tablets for large dogs that are blue. Even though my Vet taught me how to pill her, it was always a challenge and she dog would spit those large blue pills out every time I tried to give them to her. If I tried a pill pocket, she would eat the pill pocket and spit out the pill. These Chewable tablets are the best. No more Smurf Blue Fingers! Thank you!

Dog prefers pills
By WestieMom on Feb 5, 2021
When the vet put Molly on these, she would take the huge blue pills with peanut butter really well. The instructions are to give on an empty stomach so I thought the chewable would be a better choice. Well, she HATES the chewable. She’s never been a difficult dog to medicate but she will NOT tolerate these. I can break them into halves, fourths, no matter, she spits them out and will not eat them. I am now having to break them in two and coat them in peanut butter, thus defeating the whole purpose. Back to the pills after these are gone.

Super easy to keep meds in stock
By Rosiegirl on Feb 12, 2021
We are very happy that Chewy offers so many pet medicines and always much lower in price then the vet can do. Our dog is on three separate medications and we save a significant amount through Chewy. We have her medications on automatic order and that is great no worries about not getting refills on time. Plus, whenever I have called with a question or concern the staff are so pleasant and helpful always. Thank you Chewy.

Wish it would have worked out...
By Pupperone on Jan 20, 2021
I bought these for my dog, after my vet started him on the non-chewable version. He hated the non-chewable, but loved other chewable tablets from the brand- so I thought I would give these a try. What a complete waste, they are huge and even broken into 8 pieces and stuck in chicken, my dog will not touch them. He spits them out no matter what we have tried. Pill pockets, pb, chicken...nothing helps. My vet told me there is a different chewable for Denamarin advanced, but it's hard to find and the price is insane. I guess it is what it is, but would not recommend. Only positive is that the pill was easy to break up.

My pug eats everything except this
By PoiPug on Feb 2, 2021
My pug eats everything, supplements, oral care, etc but he doesn't like the taste of this. Thought this would be good for him since I have to give the pill version with peanut butter (wanted to not add to it). Bummer that he doesn't like the taste. Going back to using the pills as it's small enough for him to just swallow.

Denamarin Supplement
By meinglish on Jan 6, 2021
Was purchasing from our vet, but they didn't have any, hadn't ordered any for stock, when they did it was backordered. I checked with Chewy, they had in stock, & was cheaper. It arrived 3 days later. We get our Sugar's food, prescriptions & supplements all from Chewy now. Always faster, & cheaper than my "discount" program at my vets office. Check them out!!

Liver Help
By Denamarin on Feb 20, 2021
While Maui does not like it it does seem to help him feel better, just need to break it in two pieces and we put it in back of his mouth and he gladly swallows it.

Too early to know
By Awesome on Jan 15, 2021
Too soon to know if it will have the desired effect on lab work. The dog will not even take it in his mouth so next time I will get the one that does not get chewed. In the meantime , the chews are hidden in peanut butter.

Better than the non-chewable but still not great
By NikP on Dec 11, 2020
I had to switch from the non-chewable blue pill to this because the blue pill upset my 4 lb chihuahua's stomach. My Chi still hates the smell/taste of this pill but it doesn't seem to give him a stomach ache. I give him 1/4 of pill crushed and mixed with cheese and he reluctantly eats it. Side effect I've seen with the 'chewable' pills is dry mouth in my dog.
