BEST product, ever!
My cats are on it and I swear by it. I've been giving this to my healthy cats since I adopted them three years ago. I think it's best to be proactive (I had a dog and a cat die of cancer in the same year). Now, I want to say one step ahead of the game. I believe this supplement boosts their immune systems. If you ever have any questions, you can call American BioSciences and they will talk to you to discuss. They are as great as their products!

Didn’t help
My cat took this supplement for almost a month and It didn’t help his condition. He has diarrhea due to gastro-intestinal infection. If it helps pets with cancer, it should have helped with clearing an infection! It didn’t though! I have no complaints about the taste, size of the capsule or side effects! I might still continue giving it to my cat but I’m hopeless and I just want to try my luck.

helped a lot
Improved my beloved pet's quality of life toward the end of a battle with cancer. We used this in conjunction with herbal remedies and saw a marked improvement. I would definitely recommend this product.

Gave my dog explosive diarrhea
We tried this supplement for just 3 days and within 24 hours of the first dose our dog got explosive diarrhea 😭😭 we did not make the connection to the supplement until a couple days later. This was the only new thing added to her food so there is no other explanation as to why she would have gotten such bad diarrhea. Please use caution in starting this. We followed the instructions on the bottle and started out with 6 capsules because she is a 100 pound dog. So after 3 days of this we have immediately stopped using it.

I personally definitely think this works!
I’ve been using this for several years now for my Jack Russell terrier she’s unfortunately suffered from fibrosarcoma, Cushing’s disease, abscesses, meningioma, Just a series of bad luck she’s had stuff that Jack Russells typically don’t even have but she’s remained strong and a fighter and I definitely attribute it partially to taking this.
