It has also been shown to help protect liver cells from cell death, and may help cell repair and regeneration. While best known for supporting the liver, Denosyl also has a place in supporting brain health. It can help your best friend live a longer, healthier life

About Nutramax Dog Supplements

About Nutramax Dog Supplements

Made to Support Your Dog's Well-Being

Nutramax makes unique supplements that are formulated specifically for dogs to keep them in their best health. These high-quality supplements help support your pup's general wellness with easy-to-administer tablets, soft gel caps, soft chews, sprinkle capsules and liquids that are made for joint, liver, digestive, and skin and coat health. Nutramax canine wellness products help your dog stay young at heart so he can keep playing and living life to the fullest for years to come.

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

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.

Nutramax Proviable - DC for long-term support

Nutramax Proviable - DC for long-term support: These capsules offer natural support with seven key probiotics and two prebiotics to help get the digestive system back on track.

Skin and Coat Care

Skin and Coat Care

Nutramax Welactin Canine contains high-potency fish oil with substantial amounts of EPA and DHA, two omega-3 fatty acids responsible for skin and coat health. These important omegas not only help combat dry skin, but they also support the kidneys, brain and vision health, and a strong immune system. Many pet parents see improvement in their dog's appetite, alertness and overall appearance when they try Welactin.

  • I use this and used to use Marin

    By on

    I tried Denamarin, but it doesn't agree with his stomach waiting a 1/2 to one hour. He finds it in stuff and drops it out. This works good and he is fifteen now. Been using since he was two years old.

  • Denosyl Tabs and I/D Liver care dry food came to the rescue.

    By on

    Our 14 year old cat, Max, has diabetes and is HIV positive. Now he has developed liver issues. Our Vet gave him fluids, a vitamin shot and recommended Denosyl tabs and I/D Liver care dry food. It is two weeks later and he is almost back to his occasionally peppy 14 year old self. Thanks for making these products available. Now every day is a bonus for Max and us.

  • Cheaper than Zentonil and it's available

    By on

    My vet prescribed Denosyl for my cat because the Zentonil he had been taking is not available due to some drug regulatory issue. My cat hasn't had an adverse reaction to it, and the smaller tablet is easier to administer. Denosyl is cheaper than Zentonil. I gave it an overall rating of Good only because this is just the first refill my cat's had, so there hasn't been long-term experience with it yet.

  • Helped My Cats Creatine Levels go down!

    By on

    This is a great product! My vet recommended trying it since my cat has Chronic Kidney Disease and her creatine levels were very high. She said it may be her liver function. So I tried the pill and now within one month her levels are back to normal. And most importantly my cat takes the pill very well. Its small and I give her a little medicine dropper of water right after to make sure it goes down easier.
