Product Description

Mushroom supplement for dogs and cats

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.

NEW Enhanced Formula

Discover Our Enhanced Formula!

We've improved our formula! The new product may appear lighter in color and have a slightly different texture (but the same great taste), thanks to our innovative use of the fruiting body and mycelium of the four mushrooms instead of mushroom extracts.

We use the entire mushroom, grinding it into a nutrient-dense powder that boasts higher levels of beta-glucans and polysaccharides than extract powders. Independent testing has shown that our new mushrooms contain up to 250% more beta-glucans and polysaccharides.

I started this 10 days ago , using peanut butter pockets to put the powder in , when she wasn’t hungry for her food . Went to her check up today and has minimal fluids from her heart Tumor around abdomen and heart. No draining this time!! I’m sure this and prayers have helped her keep going. I almost put her down last Fri but I did a drain instead and 7 more days of meds and this powder, and now she’s getting better. I believe this is another reason shes doing good . 10 days so far so good! She’s 12 and my other is 14 I’m putting him on it also ASAP as well as my 6 year old Rottweiler.

I have been using this powder for about a month. My almost 10-year-old dog is going through chemo, so I purchased this powder after reading some good reviews. I want to make sure his immune system is strong enough and he stays healthy while going through chemo. I usually add to his breakfast and dinner, and he seems to like the taste he eats all his food. The change that I've notice is, he seems to have more energy, and he has been acting very playful almost puppy like. I was actually shocked the other night when he suddenly got a case of the zoomies which I haven't seen him do in months. Who's to say if it is for the powder or not but I won't take any chances, and I will continue to use this product and I will be repurchasing!

I never write reviews but Milky my Bichon Poodle almost died. After I sprinkled this product on his food, he refused to eat it. I coaxed him into eating, not realizing the danger.The next morning, he usually jumps down from my bed, but this time he was whining and needed help. When I placed him on the floor, he couldn’t walk—he couldn’t even stand on his own. I lifted him up, and he began limping across the floor. From what I could tell, only one leg was really working.Panicked, I began to pray over him olive oil mix with 2 drops of oil of oregano with black seed and gave him plenty of water to flush the product out of his system. I’m currently unemployed and was praying we wouldn’t have to go to the vet. The whole reason I bought this product was to avoid a vet visit as a preventative measure. He’s 15 yrs, but other than some possible dental issues, he’s generally fine.That entire day, he struggled to walk, limping and needing help up and down the stairs. It was a mess. I even called my pastor, who prayed for him over the phone.Then, late in the night, I heard him jump off the bed. Thank God! The next day, he was doing much better and could walk again—still a little unsteady, but by the evening, it was like nothing had happened. He was back to running around as usual.Stay clear of this stuff! I went back and read the one-star reviews, and I saw that two dogs had died after using this product. If I had seen those reviews earlier, I never would have bought it. Of course there’s no refund.If your dog refuses to eat something, trust them. Do not push it.I’m so blessed he made it through.

I think this stuff is great my 20 year-old. Shih Tzu is now running and playing with my three year-old dog instead of just laying and barking at him. He gets up and plays with him and tries to run with him and he’s in great health at 20 years old.

I got this, despite the price, just to see. My son has a seven-year-old Aussie who was no longer wanting to chase the ball, who stood back and just didn't seem to care about playing anymore with our two younger dogs. It was so sad to see! He is still so young. I remembered reading about Critical Immune Defense and seeing good reviews. So, despite the cost, I decided to order some. I gave my grand-dog, Gus, his two scoops on his food per meal for three days. (I did mention to my son that I was doing so. It is his dog, after all.) So we sailed along for three days, and all of a sudden, my grand-dog, Gus, began bursting forward to chase the ball and play. He was like a puppy again, all excited and racing around. It made my heart swell, because I was thinking, "That Stuff is actually Working!" My son said nothing. So, I thought, okay, fine. I can do without spending all that money on snake poison, even though I believed I was seeing a huge change in my grand-dog, Gus. My thought was, "I saw a placebo effect. I convinced myself, so I believed in the hype." My son didn't mention seeing a difference. So, hello, the stuff is expensive. I decided not to buy anymore. I'm not an idiot.So a few days later, my son calls. "Mom, are you still giving Gus his supplement?" I thought I had messed up, because I wasn't giving him anything. I was, like, WHAT supplement? My son was, like, that stuff that started making him play like a puppy again! My son was very upset that I had stopped giving his dog the CID. He would have been eagerly willing to continue the supplement at his own cost and trouble! The difference in the dog was huge. I became upset, only because, what? You never said a word about how it changed Gus. Why would I continue giving it to him? The stuff is expensive! I hope the company can shave away at their overhead to reduce the cost of product. Bottom line, this stuff DOES work! It isn't about buying it and only thinking it works. It truly does, and our Gus is suddenly running and playing like a much younger dog. It has given him a new lease on life. I have decided to also give it to my two younger dogs, hopefully as a preventative supplement. And, hello, I'm researching to find a human-grade supplement with mostly the same ingredients. I could stand a boost in the arm to make me feel better, too!
