Got this antioxidant supplement for my aging cat because she has been going downhill for a while. I didn’t know whether it would actually help or if there would be visible results, but I have to say there is. She’s only been using it for a few weeks but I already see more energy, and just a general overall sense of well-being. She seems happier and more alive again. And she is 16 years old! Very impressed by this stuff.
