Review: Fred is just turning 14 and for the last 1-1/2 years has been acting like a 5. - Our schnauzer Fred is just turning 14. Over a year ago our vet told us his kidneys and liver were diminishing and he was getting confused using the doggie door. Nutramax Denosyl was recommended and for the last 1-1/2 years has been acting like a 5 year old. We never expected such a turnaround including mental clarity - Wow! - Wow! - Wow! Review: helped my dogs liver level - At my 12 yr old dog's annual vet visit in January his ALT liver levels were elevated about 10 points higher than the high on the acceptable scale. It was the only value that was elevated, so my vet suggested giving Scout this supplement for a month and retest. In a month's time his value was brought back down into the acceptable level, for a total drop of about 13 points. It may have resolved itself on it's own of course, but I feel like this helped. It was inexpensive enough to try. It worked so I'm pleased with it. He's off it now and feeling fine! ## Features - High-Quality Ingredients: Denosyl for dogs contains S-adenosylmethionine (SAMe) to help increase levels of the antioxidant glutathione - one of the liver's main detoxifying agents - Support Your Pet's Liver Health: The liver, one of your pet's most vital organs, is responsible for removing toxins, storing energy, aiding digestion, and supporting the immune system - Cognitive Support: While best known for supporting the liver in dogs, research has shown that the SAMe in Denosyl may help support cognitive function in dogs - Exceptional Quality: Denosyl is backed by science and undergoes thorough quality inspections to ensure your dog receives a safe, high-quality product - Veterinarian Recommended Supplement Company: Nutramax has been a leader in pet health for over 30 years, and provides supplements to support joint health, digestive health, skin and coat health, calming, and more - Convenient Dosage for Medium Dogs: Each package contains 30 stabilized tablets specifically formulated for medium-sized dogs weighing 13 to 34 pounds, with one tablet per dose - Easy Administration Instructions: The tablets should be given on an empty stomach at least one hour before feeding to ensure optimal absorption and effectiveness of the supplement ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00076KPQ6 | | Active Ingredients | S-Adenosylmethionine 225 mg | | Best Sellers Rank | #14,495 in Pet Supplies ( See Top 100 in Pet Supplies ) #225 in Dog Multivitamins | | Brand | Nutramax Laboratories | | Brand Name | Nutramax Laboratories | | Customer Reviews | 4.6 out of 5 stars 739 Reviews | | Dog Breed Size | Medium | | Global Trade Identification Number | 00755970615906, 60755970615908 | | Included Components | no | | Item Form | Tablet | | Item Type Name | Pet Medication | | Item Weight | 9.07 g | | Manufacturer | Nutramax | | Manufacturer Part Number | DENO225MG | | Model Number | DENO225MG | | Number of Items | 1 | | Product Benefits | Antioxidant | | Specific Uses For Product | Natural Flavor | | Target Species | Dog | | UPC | 755970615906 | | Unit Count | 30 Count | | Warranty Description | Keep tablets in original blister pack until used.

When I ask ask her if she was vegan she said she wanted to feel better and that it did.so are you asking for you or your pet? **Q: What is the difference between this and denamarin? my chihuahua is taking denamarin to improve liver function. would this do the same thing?** A: My dog had complete liver failure so Denamarin was prescribed since it provides stronger liver support. They both contain the same main ingredient, but Denamarin also contains a form of milk thistle. I had a bad experience with Denosyl(my dog started vomiting black liquid, but I don't know if it was just a coincidence that he got sick the same day he took the Denosyl and I didn't want to risk it) Always consult your vet before switching or starting medications, and if your are going to buy online make sure it is a reputable company. After my incident I only purchase Denamarin from my vet even though it costs a lot more. **Q: Do you need a script from vet to order?** A: This does not require a prescription from a vet **Q: How does this compare to denamarin?** A: The central difference between the two medications is a second ingredient that is found in Denamarin but not Denosyl. This ingredient, silyb in, provides additional liver support and can work in conjunction with SAM-e to promote healthy liver function. This means that Denamarin is a stronger supplement for pets that need maximum liver support. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fred is just turning 14 and for the last 1-1/2 years has been acting like a 5. *by H***G on July 26, 2026* Our schnauzer Fred is just turning 14.

Denosyl contains the key ingredient, S-Adenosylmethionide, but does not contain SPC. My dog is doing well with Denosyl, but check with your veterinarian before making a substitution. ## Frequently Bought Together - Nutramax Denosyl Liver and Brain Health Supplement for Medium Dogs - With S-Adenosylmethionine (SAMe), 30 Tablets - Purina Pro Plan Veterinary Supplements FortiFlora Dog Probiotic Supplement, Canine Nutritional Supplement - 30 Ct.
