Azodyl® is a breakthrough, non-prescription medication that helps support kidney health. Each coated Azodyl tablet contains a patented formula of beneficial bacteria that reduce toxin build up in the body.

  • Natural formula supports healthy kidney function
  • For dogs and cats
  • Fast acting, safe, and no side effects
  • Small capsules are easy to dose

The kidneys do critical work, filtering waste and toxins from the body. But if your dog or catís kidneys arenít functioning properly, then the kidneys could be damaged and other problems can occur. If your pet needs renal (kidney) support, talk to your veterinarian about Azodyl, a nutritional supplement that supports kidney function. The patented, naturally occurring beneficial bacteria in each Azdoyl capsule work to flush toxins out of the bowel and blood and slow further toxin build up in the body.

METHOD OF ACTION: Helps support normal function and health of kidneys

TREATMENT: This treatment is important for pets with Chronic Kidney Disease (CKD), which begins with azotemia. Azotemia occurs when nephrons decline and non-protein nitrogenous compounds build up, impairing the kidney's ability to filter and eliminate waste. Azodyl helps reduce azotemia and slows the progression of CKD. Azodyl is safe to use and is compatible with other therapies.

Benefits Azodyl
  • Same amount of probiotic bacteria as the larger size capsules
  • In a 50% smaller capsule for easier administration
  • Ideal for small dogs and cats, but can be used in any size animal
  • Same enteric coated capsule as the larger size capsule
  • Same administration directions as the larger size capsule
  • Larger capsule count per bottle for long-term administration

Azodyl® is a brand name for a probiotic supplement used to support kidney health in cats and dogs that have kidney disease.

Dietary supplements are substances that can be used to supplement the diet, such as vitamins, minerals, amino acids, herbs, botanicals, enzymes, and probiotics. While many supplements are sold over the counter, they still contain ingredients that have biological effects that should be managed by your veterinarian. Follow your veterinarianís directions and cautions very carefully as their directions may be significantly different from those on the label.

There are differences in how countries regulate supplements. In the United States, these substances are not as vigorously regulated by the US Food and Drug Administration (FDA) as other medications, which means they can be sold without the manufacturer proving their effectiveness and safety, and without a guarantee of consistent or accurately reported ingredients. In Canada, products that have been evaluated for quality, safety, and effectiveness by Health Canada and authorized for sale will have a license number on the label.

Azodyl® works by adding nitrogen-consuming bacteria to the intestines. These bacteria break down the increased waste products resulting from the kidneyís impaired ability to eliminate them.
Limited studies involving rats, cats, and pigs have found positive results, however other studies have contradicted these results in cats and dogs. Therefore, a treatment trial would be recommended to evaluate effectiveness on a case by case basis.
Azodyl® is given by mouth in the form of a capsule. It may be given with or without food. Do not open or crush the capsules; give each capsule whole.
If you miss a dose, give it when you remember, but if it is close to the time for the next dose, skip the dose you missed and give it at the next scheduled time, and return to the regular dosing schedule. Never give your pet two doses at once or give extra doses.
Side effects with Azodyl® are rare. Notify your veterinarian if you notice anything unusual while your pet is on this supplement. There are no known risk factors for using Azodyl®.
There are no known drug interactions with Azodyl®; however, vitamins, herbal therapies, and supplements have the potential to interact with each other, as well as with prescription and over the counter medications. It is important to tell your veterinarian about any medications (including all vitamins, supplements, or herbal therapies) that your pet is taking.
There is no specific monitoring that needs to be done while your pet is taking this medication. Your veterinarian may monitor your pet to be sure that the medication is working.
Store this supplement in the refrigerator.
If you suspect an overdose or an adverse reaction to the medication, call your veterinary office immediately. If they are not available, follow their directions in contacting an emergency facility.

Dog does not like the taste, but it is effective in keeping creatinine stable. This plus the phosbind is a great combo to keep kidney values low.

I also recommend purchasing from this company because the azodyl arrives very cold. Delivery was quick and the azodyl was kept at optimal temperature. Do not order from Amazon because the azodyl arrived WARM! This medicine needs to always be kept refrigerated

Awesome help for CKD cats. I try to avoid summer months for obvious reasons, so I ordered pre-spring. Product came cold & *super protected* with cold packs & packaging. Never ever have I experienced such awesomeness in the delivery of this product from other companies. I am so delighted! I am stocked up for now & will reorder once hot weather ends.
  • Helps kidneys improve functioning by elimination of toxins. A very serious product.

My dog is in renal failure and we’re spending a lot of vet bills, meds, and supplements, so it was a blessing to find it here, with a good coupon. It shipped immediately, and was packed in ice bags. It arrived in perfect condition, and I will continue ordering.

Product has prevented CRF in my 15.5 year old cat
December 20, 2023
I have been using this product for several years after testing showed that my cat had the earliest signs of kidney problems leading to chronic renal failure. I found the best price for this relatively expensive supplement at Entirely Pets. My cat has shown no signs of advancing kidney disease. Chronic Renal failure is very expensive and difficult to treat.
  • Easy to give and works.
  • None except expense.

I treat one of my cats who was born with kidney malformation and hence kidney disease. This product has been keeping his kidney values in an acceptable range (high end of the normal range) for the last 5 years. Of course, we check his kidney values every six months, and so far so good. We will continue using Azodyl. As for EntirelyPets, I am very happy with the prompt service and above all, with the care with which Azodyl was shipped in a special pouch to keep it refrigerated It got here in less than 2 days, still refrigerated. Will certainly reorder from this company.

Really Works
September 25, 2023
My 10 year old cat was diagnosed with moderate kidney disease. Even with special food and subcutaneous fluids, her creatinine and BUN levels were increasing. I brought my cat to the vet for bloodwork August 7th 2023 and again September 18th 2023. I bought these probiotics right after her first August appt and in a month her Creatinine level went from 3.6 to 3.1 and her BUN level went from 56 to 52. I will keep her on these probiotics for the remainder of her life. The toxins that build up from the kidneys not functioning correctly can really make your kitty not feel good and affect their appetite :( These probiotics are important for cats with CKD.
  • They work
  • Cat can't taste them
  • Easy to break apart and mix in food
  • Expensive (but worth it)
  • Must be kept refrigerated

This supplement helps my cats!
October 16, 2022
I have two 18-year old cats. Both have what their Vet calls "renal insufficiency", which to my understanding means that their kidneys no longer work as efficiently as they did when they were young. My cats' Vet recommended Azodyl, as it helps clean the toxins out of their bloodstream that their kidneys are allowing through. I give them both one capsule a day. I have bloodwork done on them every 6 months to check how they're doing. Their numbers improved and then stabilized. Their Vet is very pleased and both my cats seem alert and engaged. They've had no problems with it. I highly recommend giving Azodyl a try if your cat or dog has kidney issues. I also recommend checking with your pet's Vet for their okay, I recommend that with everything involving pets not just this product. Just remember that this supplement needs to be kept refrigerated so that the probiotics stay alive and efficient. Entirely Pets ships it beautifully and it's always arrived on ice. I've attached pictures of Willow (she's a mostly white cat) and Emma (she's a dark tortoiseshell). Both photos were taken recently.

Merchant Response:Hello Cheryl, We're so glad to hear you're seeing improvements! we greatly appreciate your feedback and the photos of your pets.
  • Easy to administer to my two cats. And it definitely helps them! I am so glad their Vet recommended this supplement for them.
  • None at all.

Great Product and Excellent Shipping.

This is a great product for your kids with CKD. And the shipping was fast and correctly packaged. You should take a closer look at the studies performed by KIBOW and really get a glimpse into how these kinds of supplements work - it's fascinating. To think of how these billions of microorganisms are helping to clean our babies insides is so cool. I can only say good things about the research and work put into Azodyl and its more concentrated companion dosage Renadyl.
  • QRIO, we also find it fascinating that live microorganisms can help when other organs need a hand. As I say, Are we hosting billions of bacteria or are billions of bacteria hosting us?

This product saved my cat life. I started to purchase from my country, Romania but i found it cheaper on this site. even the distance SUA-Romania is about 10 000km, EntirelyPets sent the purchase wonderful, very well packed and cold. I was nervous to be honest but it was a great experience. Even with a lot of money i give in tax to the border, it is still cheaper.

I really like this product. It has really helped my dog's kidneys since they were damaged from Lyme Disease.
  • Great kidney support
  • I think this product is very expensive for the amount you get and it must be kept cold. This isn't a problem in the winter, but during the summer you have to know when it's being delivered so it doesn't sit outside. Also a lot of times they won't let you use coupons on the product and customer support is less than friendly. I
