Naturally Potent Supplement Powder

The innate immune system is your pet’s first line of defense against all infectious organisms. Unfortunately, there are many factors that can compromise your pet’s immune system, leaving your dog or cat vulnerable to illness and disease.

Dr. Bill’s Immune Support can provide added protection by enhancing the ability of your pet’s innate immune system to detect, track down, and kill invading organisms. Giving your pet a pill can be a challenge, that’s why most of our supplements are formulated as a powder that can be sprinkled dry onto any diet or moistened to make a tasty, nutritious broth. It’s easy and pets love the flavor.


This potent blend of immune enhancers bolsters your pet’s natural immune response, increasing its ability to defend against disease and aid in cellular protection.

Immune Support contains a patented and proprietary long chain Beta 1,3 1,6 D-Glucan that scientific research has shown can have a positive impact on the innate immune system, raising it to a level of peak effectiveness.
Immune Support has been shown to be safe for dogs and cats of all ages.
