"Wish there was a human version!! Our large male German shepherd was getting growths on his neck and by his eye. They were getting larger. I saw this product and ordered one canister, not expecting much. However, within 2 weeks, the growths were getting smaller. They finally disappeared! We now give this as a preventative to both of our dogs! Highly recommend it!! Worth the money!!" - Carla

"Here’s my Puggy's 2nd bottle. In my 1st bottle in only a week, I noticed he was more playful & energetic. I was surprised because every day now, he wakes me up wanting to play. Before the end of 1 bottle, his soft lump flattened. We are still working on diminishing his other soft lump under the breast bone. So far, I’m impressed. I believe. I also noticed his ear allergies are gone. He usually has an ear infection. Looks like his ears have no yeast that he used to scratch. I will continue & look forward to order again. More power." - Lina

"Where do I start?! My 10-year-old German Shepard was diagnosed with an anal gland tumor that was causing her discomfort during bowel movements and also causing bleeding. I changed her diet to a fully organic natural diet (No Kibble ) and began to use critical immune defense. After several weeks of using it, I saw significant results to the point where the tumor was significantly smaller. It's been 11 months since she has been using critical immune defense, and she is a completely different dog. She is energetic and playful, eating, and has normal bowel movements. Her blood work came out negative 6 months ago, and she has been thriving ever since!! I cannot thank this product anymore for providing my dog with such important nutrients and immune support she needed during her time of need. I will continue to give her this product for the rest of her life." - Jonathan

“My little guy here has a fatty tumor on his side, and sadly, the vet took X-rays and found a tumor on his heart. I started him on your product a couple weeks ago, and he has gotten more energy is more alert, and can get in and out the doggie doors by himself again. I will definitely keep him on your product, and I am hoping it may shrink the tumor on his heart, either way the vet was ready to send him over the rainbow bridge I said no I was going to try your product! He is a changed dog, and he used to cough often, and he doesn’t as much!thank you for giving me more time with him!” - Heidi

"This supplement has saved my dog’s life. She is a completely different animal, now. She’s an 11-year-old Maltipoo and was diagnosed with lymphoma last April. She was on chemotherapy, and this supplement along with a healthy greens supplement for 3 months, and her cancer is gone. I have kept her on these supplements, and they continue to work miracles in her little body. She also used to have the worst skin issues, constantly having things removed, and she was just generally not healthy. It’s unbelievable how healthy, happy, and energetic she is. It truly is a miracle!" - Adelle

Your pet's immune system is the key to its health! Here's why:

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

Let’s face it. Your pet 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 pet'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

THE DOCTORS AGREE

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.

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

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

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

“Certain mushrooms and turmeric may be beneficial in helping your pet to boost its immune system to fight diseases,” explains Edwards.

“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.

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!
