Really helped my 14-year old lab
My vet prescribed this for my 14 year old lab who had liver issues, which we discovered after a blood test. The vet said she was otherwise healthy, and could very well live another year if we got the liver stabilized. She gets a one daily pill now, and it has drastically improved her quality of life. You could tell before she was tired, sore, she never ran, struggled to get up some basic stairs and didn't like going for walks... after a few days on this, she was wagging her tail again, and even running and jumping which I hadn't seen her do in probably a year. She'll walk a mile or more with us now and seems happy, head up and tail wagging the entire time. It's made a big difference for her quality of life in her elder years.

Liver enzymes back to normal
Helps my senior dogs’ liver enzymes. All 3 were elevated and now back in the normal range! A bit expensive but works to keep my girl healthy

Vet recommended, good quality, priced right
I'm only giving it four stars for now because I'm so happy my dog will even eat these! (I do need to wrap them in a slice of turkey but I'll do anything to get medicine in him!). His doctor said to try these for a month because his liver enzymes were high, so I can't say "they work" or anything like that because we still have two weeks to go. They seem to be well tolerated - no side effects that are obvious. The price was less than I expected when the doctor told me to order them. (It seems every time there is a new vitamin or medicine, it's almost $100+ !!). Fingers crossed!

Nutramax Denamarin
Our veterinarian recommended my elderly dog take Denamarin as a supplement. She takes it on an empty stomach daily and seems to be doing very well. For my own convenience, I place a pill inside of a pill pocket and she thinks she’s getting a treat and that way I’m not stressing and neither is she about chewing a pill. The price was outrageous at the vet’s office, so I looked on Amazon and Voila, this is where I will purchase it from now on.

Cheaper at the vet for the quantity.
I can get it at the Vet for Large Dogs, one tablet instead of 2 capsules a day. For the price, it wasn't worth it.
