The #1 natural health secret that keeps pets healthy and happy!

NK-9’s ingredient, AHCC, supports a pet’s immune system by increasing Natural Killer (NK) cell activity.

NK-9 usage

"We strongly believe that NK-9 has given Jack (14 yr old beagle on NK-9 for 2 years) added years, and we are so grateful to have him spend that time with us. He shows no sign of declining health, and in fact he seems healthier all the time."

Jan O., Florida

"We have two old mixed breed dogs and we have been so pleased with the increased energy in them after using NK9 and DGP. There have been no side effects and we are so happy to have our pets doing so well."

Cici V., Virginia

"Hospital work is grueling for our working dogs. We provide Animal Assisted Therapy Programs, Service Dogs, and Dog Training in the Atlanta area. It takes highly trained, healthy dogs to provide patients with the best service. We rely on NK-9 and DGP to keep our dogs healthy and sound."

Kellie C. at Cosby's Therapy Animals, Georgia
