FAQ
VetSmart Formulas were originally designed for veterinarians. This means they deliver the clinical-strength quality and efficacy veterinarians demand in the products they provide and recommend. This product is wheat-free and contain no artificial colors or flavors. Moreover, it can be used along with most products and prescription medications available for pet consumption.
Thousands of dogs in all sizes and weights continue to benefit every month from VetSmart Formulas to boost their immune system and overall health. If your dog has a situation similar to the other dogs you may have read about in our reviews, then this product may likely help your dog too. Critical Immune defense helps protect your pet against: Abnormal cell growth Harmful pathogens such as bacteria, viruses, fungi, and parasites Inflammation Infection Cardiovascular disease Hormone imbalance High blood pressure Arthritis Liver damage … and more.
When your pet’s immune system is functioning at an optimal level, it will naturally balance the “normal activity” that should take place. The immune system fights infections, and removes harmful viruses and bacteria, and it slows the aging process. A strong immune system will also boost Natural Killer (NK) and T-Helper cell production that helps prevent and slow cancer cell reproduction. So, a strong and healthy immune system will keep your pet safe and healthy!
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.
No pet is too old to start using an all-natural product that will help them live a better and longer life! It’s similar to someone who starts exercising at 80 years old. Every bit helps! Start now and you will help to prolong your pet’s lifespan!
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.
Yes, absolutely! There is no problem using all the products together. And… good for you for being on top of your pet’s health!
Yes. Our product is all-natural and designed to be taken with chemotherapy medications. It will help boost their immune system that might be compromised by the chemotherapy medications. If your pet is being treated for any serious medical condition, we always suggest that you discuss the use of any supplements with your veterinarian. You can simply bring the bottle to them during a visit or take a photo of the label and share it with your vet.
Yes. Our product is all-natural and designed to be taken with prescription medications. It will help boost their immune system that might be compromised by the medications. Again, we always suggest that you discuss the use of any supplements with your veterinarian. You can simply bring the bottle to them during a visit or take a photo of the label and share it with your vet.
We can’t guarantee that, but what we do know is our product is very effective at boosting your pet’s immune system which helps fight all types of diseases such as cancers. The research on the ingredients in Critical Immune Defense is very extensive and Asian cultures have used these ingredients effectively for many centuries.
Critical Immune Defense is very easy to give to your pet. It’s a powder that you simply sprinkle on their food. It has a natural hypo-allergenic chicken flavor that appeals to both dogs and cats, and most pets love the flavor. We offer a 30-day money back guarantee if they don’t like the taste.
We agree. The numbers are frighteningly high! These statistics were published by the Veterinary Cancer Society. There is so much research and so many clinical studies on the percentages of dogs and cats that get cancer. You can Google it and see the various studies online.
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.
We love this question! Our product is one of the most powerful immune boosters for pets on the market. We have combined a blend of four mushrooms along with turmeric and vitamins to create what we feel is the absolute best immune booster for pets. Our ingredients are standardized to the highest potency and the product is veterinarian strength. We invite you to compare the labels and the ingredients in our product to any others on the market to see for yourself!
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.
Please do your own online research to learn more about the benefits of the mushrooms in our product and the research being conducted. It is quite amazing!

My cats won't eat it :(

I have two cats with thyroid issues (one is hypo and one hyper) and my senior (age 16) either has IBD or cancer and takes steroids. I was really hoping for nutritional support to help with these issues, after reading all of the positive reviews. Unfortunately, my cats will not eat their wet food if I put this powder in it (even a little amount). So I just wasted my money, which is very disappointing. I thought this company had a money back guarantee that I saw on social media, so my next step is to email them I guess. I just want my kitties to be better!

We have two 10yrs old cats and two 2-3yrs old dogs. One dog has sensitive and cats are middle age. Thought an immune boost would be all around helpful. Eased cats and dogs into this product over 3-4 days then full recommended dose. At day 6 we have one cat and one dog feeling unwell. Cat acts unwell, cry when picked up. 2 yrs old dog acting odd and unwell. I have discontinued immediately. Something is wrong.

I believe this is improving my dogs quality of life
My dog is 11 years old and has recently been sick. We thought we were going to have to put him down but he rallied and is still alive. The vet believes he has cushings
My dog is 11 years old and has recently been sick. We thought we were going to have to put him down but he rallied and is still alive. The vet believes he has cushings disease and after some research he fits all the criteria and I believe his is very advanced. Unfortunately, he needs steroids to help keep his inflammation from his arthritis down therefore he can't get the testing done to confirm Cushings and get the medication. Regardless, I did some research on natural remedies for Cushings. I started giving him this and the Melatonin and Lignans. Together I noticed a bit of a difference. He began parking up a bit and getting some tail wags. His panting isn't as bad and he seems less restless. We are almost through a whole bottle and I reordered another. He is very picky so I mix it with peanut butter and make him a peanut butter sandwich with it. He is basically palliative and with the cushings he's been losing a lot of weight despite rabidly eating. Regardless, I believe that this has gained us more time with our buddy and has given him some quality of life. He perks up and gives us tail wags. So I believe it has helped him and has been worth the money.
Great product
I like that it uses natural ingredients like turkey tail mushrooms appealed to me as I use them for my own immune support.

My dog was diagnosed with stage 2 sarcoma. Surgery removed the mass but couldn't get it all. Within the year it grew back. Nothing else could be done. Called in a hospice veterinarian to help with final plans when the time came. My regular veterinarian told me about turkey tail for cancer in dogs. I started using it twice daily in his food. In six weeks the mass was gone. It has been almost a year since I started using it. He still has cancer but turkey tail has slowed it. I'm grateful to still have my baby. He just turned 14. I'm grateful every day I have him. I use one bottle every month. Easy to mix in food.

My Golden Retriever Jack was diagnosed by our vet with mouth cancer due to a malignant growth in his mouth. The vet removed as much of the growth as possible and gave him six months to live. We began giving Jack this mushroom and turmeric formula shortly thereafter. The vet re-examined him and was puzzled since the growth has shrunk and it wasn't spreading to his bones like he thought it would. It has now been over nine months, and our dog is now 12yrs. old and appears to have more energy. We will definitely continue using this product and recommend it. As another reviewer stated cancer hates mushrooms.

I've been giving my cat Critical Immune Defense for about two weeks now, mixing it with her wet food and Delectables Squeeze Up treats. Unfortunately, her fibrosarcoma on her ribcage doesn't seem to be shrinking. She's already had two surgeries, and a third might be necessary. I'm really hoping the CID will start working soon.
More energy
After just one week of use Milo seems to have more energy and is a younger version of himself, wanting to play more. It's too soon to tell if it helps with his bumps
After just one week of use Milo seems to have more energy and is a younger version of himself, wanting to play more. It's too soon to tell if it helps with his bumps (which is the reason I'm trying it). He also loves the flavor and has no hesitation about eating his food with it mixed in.
