    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 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 cats and dogs 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.

    Amazing for my Senior Dogs!

    My 11.6 yr old boy had an anal gland infection that would Not go away. We did 4 x 20 day strong antibiotic treatments for him at the cost of $191.00 per treatment. A friend told me about this product, so I got it. I gave it to him on his food once a day (cuz that’s how we feed), it went away in about a week. I used up the first bottle, waited a couple weeks to see if the infection came back, and it did within about 3-4 days. Started him back on the Critical Immune Defense and the infection went away within 3-4 days, without putting him on any antibiotics. Went through another bottle (infection stayed gone), took a few days off again just to see if the infection would come back, and it did! Also his old man cloudy eyes, and joint stiffness went away too on this product. My old 10 yr old girl who hasn’t shown any issues is also on it and looks and acts like a puppy. No one believes they are as old as they are. Their coats are beautiful shiny and look like they just had fresh baths every day too. I would highly recommend this product to anyone. Our dogs are very athletic Belgian Shepherd Groenendaels. Now I even give it to our young dogs. Just half as much. Great product!

    Large lump

    My dog Diesel has had small lipomas last 4 years. The worst one the vet has been following is near his liver/abdomen which has become the size of a small cantaloupe. He hasn’t been to the vet for 2 years because I think they will want to run tests and biopsy it for cancer but that isn’t going to happen. He is 12 now and this is the 2nd time he has been on the critical immune defense powder with good results. His small lipomas have reduced in size and the large one by his liver has also gotten smaller. I pray it keeps shrinking and takes the pressure off his abdomen so he can live longer with us.

    Critical Immune Defense

    My 13 year old Golden had a cancerous breast removed over a year ago. I was told she may have more lumps develop and I was to keep an eye on her. I found your product right after her surgery and decided to give it a try. She has been on your product since that time, and no more lumps have developed. She is more alert, and her fur also came in thicker and longer, and I had to take her to a groomer for the first time ever for a de-shed. Thank you for your product!!

    Critical Immune Defense

    It’s been four weeks since Panda began her 2x daily. We are optimistic but have not yet seen a detectable change in terms of her bumps and lumps. Will report back over the next eight weeks.
