Your dog's immune system is his first line of defense against illness, just like yours. But stress, poor diet and aging can all take their toll on your pet's immune system, leaving him vulnerable to illness and disease.

NK-9 Immune System Support helps provide unsurpassed support for your pet's immune system, especially their NK cells -- a type of white blood cell known as the immune system's front-line defense. NK-9 contains AHCC (Active Hexose Correlated Compound), which is backed by more than 20 published studies and clinical experience with both humans and K9s.

NK-9 is "the" AHCC product specifically formulated for pets. AHCC is a mushroom hybrid compound that's proving to be a nutritional all-star. Studies show AHCC has the ability to help dogs maintain optimum killer cell function, support cytokine production and promote optimal T-Cell and macrophage activity.

It will dramatically enhance your dog's immune defenses, keeping him healthy and active at all ages.

NK-9 is manufactured by American Biosciences, the first company to offer solid support for canine health based on published scientific research. Their goal is to help people and pets enhance their lives and health through the most effective natural dietary supplements supported by outstanding research.

Each bottle contains 30 capsules.
