We feel this veterinarian does a great job of explaining the immune system in a simple and effective manner:

“The immune system acts like a nonstop housekeeper”, describes Dr. Donna Raditic, an American College of Veterinary Nutrition (ACVN) diplomate who does consulting on nutrition and integrative veterinary medicine in Athens, Georgia. “It identifies potentially harmful pathogens like bacteria, viruses, fungi, and parasites, then works to eliminate them before they can do harm. 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,” Raditic explains.

The time to start any preventative action is before your pet has an issue. As dogs and cats age, their immune systems are not as strong, and they are more susceptible to diseases. A weak immune system in dogs and cats can cause a variety of diseases such as infections, diabetes, osteoarthritis and cancers. Be a proactive pet owner and start boosting your pet’s immune system while they are younger and BEFORE they have an issue.

Not likely. However, if you know (or think) that your pet has a sensitive stomach ease into the product slowly. Start with 1/3 or 1/2 the recommended dose and work your way up to full dose over a 1-2 week period. If you notice any issues, simply stop using the product or cut back to find the level that works for your pet.

No, they are not. Turkey Tail Mushroom, also known as Coriolus Versicolor, is a common type of mushroom that has the shape and color of a turkey tail. What is unique about the Turkey Tail Mushrooms that we use in Critical Immune Defense is the mushrooms are harvested at a very young age when the polysaccharide K (PSK) and peptides are the most concentrated, and these active compounds boost the immune system. As a reference, polysaccharide K (PSK) is an approved mushroom product to treat cancer in Japan.

Here’s a way to think about it. High blood pressure is known as the “silent killer.” That’s because people may have high blood pressure for many years and not notice it. However, because there are no visible signs does not mean nothing is happening in your body. The same is the case with boosting your pet’s immune system. You may notice that your pet is more lively or peppy, or you may not notice anything at all. Keep in mind that not seeing a visible result does not mean the product is not working.

Most mushrooms are very beneficial to humans and both cats and dogs, and less than 1% of mushrooms are harmful. The mushrooms that we use in Critical Immune Defense are “medicinal mushrooms” and they have been used to boost immune systems for centuries and are proven to be safe and effective for cats and dogs. For more than 30 years medicinal mushrooms have been approved as cancer treatments in Japan and China. More recently, the U.S. Food and Drug Administration (FDA) has approved clinical trials for Turkey Tail and other medicinal mushrooms.

"We didn't discover turkey tail," says lead investigator Leanna J. Standish, PhD, ND, LAc, FABNO, Medical Director of the Bastyr Integrative Oncology Research Center. "It's been used in Asia for thousands and thousands of years, and it turns out to be a really potent immune therapy. The significance, I think, is that we're bringing a new medicine to cancer patients in the U.S."

Studies are being conducted at several U.S. research universities, including the University of Pennsylvania School of Veterinary Medicine to gather data on the cancer and tumor-fighting effects of mushrooms in dogs, and the development of transformative cancer therapy for pets.

The new product may look lighter and have a slightly different texture (but the same great taste) due to using the fruiting body and mycelium of the four mushrooms, instead of extracts.

Traditional extracts lose nutrients during heat processing, but our method preserves them. The fruiting body is the cap and stem, and the mycelium is the nutrient-packed roots. Our improved mushroom powder contains up to 250% more beta-glucans and polysaccharides, known for their health benefits, including anticancer, antibacterial, and antiviral effects.

Our mushrooms are also organically grown in Canada using sustainable, patented growing processes. Experience the powerful benefits of our enhanced formula and give your pets the best in health and wellness!
