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. ## 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.
