Critical Immune Defense™️

FIGHT VIRUSES, DISEASES, AND CANCERS.

Your pet's immune system is the key to its health

In today’s world, viruses and diseases are rampant, and it can be challenging to protect your pet.

Let’s face it. Your dog and cat lives in a world filled with contamination.

They spend 90% of their waking hours on the floor, mopping up toxins, chemicals, and pollutants.

The household cleaning products, fertilizer on the lawn, and preservatives in their foods can be harmful. Bacteria, airborne contaminants, and viruses transmitted by humans can challenge their health.

Most pets do not eat an optimal diet, and likely do not get as much exercise as they require.

What do you do?

You need to put your pet’s immune system in overdrive!

Research shows that a well-balanced and functional immune system is essential to your pet’s overall health and well-being.

"The immune system acts like a nonstop housekeeper", describes Dr. Donna Raditic, an American College of Veterinary Nutrition (ACVN) diplomate in Athens, Georgia.

It identifies potentially harmful pathogens like bacteria, viruses, fungi, and parasites, then works to eliminate them before they can do harm.

And a dog’s immune system monitors cells to ensure they’re working properly.

“When other cells are aging or functioning abnormally—such as a cancer cell reproducing too rapidly—the immune system attempts to step in and maintain proper physiological function and balance,” Dr. Raditic explains.

Cancer Rates Are Skyrocketing

More dogs and cats are being diagnosed with cancer than ever before. 

According to the Veterinary Cancer Society, almost 50% of all dogs and 32% of all cats over the age of 10 will develop cancer. Younger pets are also increasingly at risk.

“Cancer is affecting our pets at alarming rates, and it is devastating for both the families of these pets as well as the pets themselves. I am seeing this in my practice on a regular basis.”

Dr. Jennifer Edwards, Veterinarian at Ponemah Veterinary Hospital in Amherst, New Hampshire.

“One of the things that can be helpful is supporting your pet’s immune system with antioxidants to help its body to use its own natural defenses against disease. Certain mushrooms and turmeric may be beneficial in helping your pet to boost its immune system to fight diseases,” explains Edwards.

According to Dr. Edwards, another way to protect your pets is with all-natural health supplements

Pet owners CAN make a difference.

“It is the responsibility of the pet owner to do everything possible to minimize the risk of cancer in their pets. This includes a sensible lifestyle with sufficient exercise, weight management, drinking clean water, healthy food intake, and avoiding toxins.”

– Dr. Shawn Messonnier, Veterinarian and Founder of Paws & Claws Animal Hospital in Plano, Texas.

“Giving your pets a high-quality antioxidant supplement is highly recommended to further reduce the risk of cancer.”

Mushrooms = Anticancer Activity

“As a pet lover, I think it makes sense that the compounds in mushrooms be included in your pet’s diet or included by nutritional supplements. Certain mushrooms contain agents with anticancer activity and immunomodulatory properties that may help fight cancer and certain other diseases.”

Dr. Frank Markland, Professor of biochemistry and molecular medicine at the University of Southern California Keck School of Medicine.

White Turmeric Root Extract

Turmeric has been used for centuries to reduce pain and inflammation. Its active ingredient, curcumin, has proven to be effective at blocking the growth of certain cancers and protecting against neurodegenerative diseases, arthritis, cardiovascular risks and liver damage.

Our proprietary extract is six times more bioavailable than standard turmeric root, which means it’s more effectively absorbed into your pet’s body and they need less of it to get the same effect. It’s also colorless and milder tasting, making it easier to handle -- and tastier for your pet! No more turmeric stains!

Your pet’s immune system is one of the most critical parts of its health.

It’s your job to feed and nourish it, and make sure it operates at optimal levels to fight disease and cancers.

Customer Testimonials

“The Difference In His Health And Energy Is Amazing!”

Kelly B.

My beautiful dog Hooch was diagnosed with cancer a few months ago. I’ve been using Critical Immune Defense combined with your probiotic for about a month and the difference is amazing! Hooch seems to be in better spirits and he is eating again. He saw me taking one of my other dogs for a walk and came to the fence and put his nose on the leash like “I want to go too.” I know he is feeling better, and I feel that the Critical Immune Defense and the Probiotic are working!

Judy W.

My dog had been on steroids for a back injury and developed a bacterial skin infection as a result. I was concerned he might have immune system problems. This product is made in the USA and is all natural, and I can use it with his allergy meds & antibiotics. He loves the taste, even licks the bowl to get it all. I think this product has helped him very much to combat this bacterial infection. He is 11 yrs old and I want him to live a long, healthy life.

Jesse & Todd L.

We highly recommend Critical Immune Defense! Our 8 year old Golden Retriever gobbles it up and we feel so good knowing it's an all-natural product (and made in the USA). Thank you for making it so easy to boost our dog's immune system!

Tamara W.

My dog loves Critical Immune Defense. No problem with taste and the ingredients are great. He’s an old timer -- 15 ½ years old -- and 70 pounds and he’s doing well despite diabetes and a neurological impairment. He still goes for his walks, albeit, very slowly.

Not only is it easy to use (just sprinkle it over your pet’s food) -- your pet will love the taste!
