ThrivingPets Aluminum Hydroxide is a phosphorus binder for cats and dogs with renal failure. This product is odorless and tasteless- making it a great choice to mix into food or administer with a treat. ThrivingPets Aluminum Hydroxide powder is the most popular form of this medication and currently has an expiration of 11/31/26. The technical name of ThrivingPets Aluminum Hydroxide Powder is Dried Aluminum Hydroxide Gel Powder. Returns of ThrivingPets Aluminum Hydroxide Powder are prohibited by law.


Aluminum Hydroxide should be administered with food. This is a dose-to-effect medication. Aluminum Hydroxide powder contains a minimum of 1,200 mg of Aluminum Hydroxide per teaspoon. There are approximately 40 teaspoons of powder in the 100 gram jar. For dosing recommendations, please see Dr. Larry Nagode's dosing recommendations here- Aluminum Hydroxide Dosing

For wet food: Place the food in the serving bowl, add the ThrivingPets Aluminum Hydroxide Powder to the food, add water equal to 3 times the amount of the powder, mix thoroughly, and let the food sit for at least 15 minutes before serving. The water and letting the food sit are to help the powder hydrate and the particles to break down so your pet can't detect the powder in the food.

For dry food: Place the daily amount of food and ThrivingPets Aluminum Hydroxide Powder into a ziplock bag and shake well. Let sit for at least 4 hours to allow the powder to absorb into the oil in the food.

Why ThrivingPets Aluminum Hydroxide?

ThrivingPets Aluminum Hydroxide Powder is the highest quality, most potent, and safest product on the market. ThrivingPets Aluminum Hydroxide Powder contains minimum 1,200 mg per teaspoon- the highest concentration available. Other products in the marketplace contain only 1,000mg per teaspoon. With ThrivingPets Aluminum Hydroxide Powder you administer less powder, save money, and can be confident in the purity and safety of our binder compared to Phos-Bind.


A 2001 study by Peter Markewell (BSc, BVetMed, MRCVS) for the Waltham Centre for Pet Nutrition found that "...using a phosphate- and protein-restricted diet, in combination with oral phosphorus-binding agents in those cats in which control of hyperphosphatemia [high phosphorus] and RHPTH [renal secondary hyperparathyroidism] was not achieved by diet alone, resulted in more than doubling of average survival time from the commencement of treatment."

Drug Interactions 


Potassium Citrate 

As Prescribers' Digital Reference mentions, products containing citrate may increase the absorption of aluminium, which could increase the risk of aluminium toxicity (though apparently these findings have not been replicated in cats). The most commonly used citrate-containing products in CKD cats are potassium citrate (perhaps to treat metabolic acidosis), and many therapeutic kidney diets.

  If you are using potassium citrate, give this at least two hours apart from aluminium-based binders.

Other Interactions

Chronic kidney disease (CKD) in dogs and cats — staging and management strategies (2015) Chew D A Presentation to the Virginia Veterinary Medical Association 2015 Virginia Veterinary Conference says "Due to varying effects of intestinal phosphate binders to limit absorption of drugs, it is advisable to give other drugs 1 hour before or 3 hours after any intestinal phosphate binder is given."

 The following specific interactions are noted:

  • Plumb's also recommends separating aluminium hydroxide from corticosteroids.

  • Aluminium hydroxide should ideally be given separately from oral iron supplements because the aluminium hydroxide may reduce the absorption of the iron.

  • Plumb's Veterinary Drug Handbook also advises giving aluminium hydroxide two hours apart from famotidine (Pepcid AC), which is used to treat excess stomach acid, because it may interfere with the absorption of the treatment, which would make it less effective. However, RX Med states that "concomitant use of aluminum hydroxide/magnesium hydroxide at commonly used doses, does not influence the pharmacodynamics or bioavailability of Pepcid AC." I would try to err on the side of caution and still separate famotidine from phosphorus binders and ACE inhibitors if you can, but if this is difficult for you, e.g. because of work commitments, just do the best you can.

  • Aluminium hydroxide binders should be given two hours apart from ACE inhibitors, because the binder may reduce the bioavailability of the ACE inhibitors. Drugs has more information about this.

  • Pennstate Hershey mentions that vitamin C may interact adversely with products containing aluminium, such as phosphorus binders. Cats do not need vitamin C supplements anyway, because their bodies can manufacture all the Vitamin C they need.

Quick and responsive. Having a problem with a container for the meds, they contacted me immediately to find an alternative to getting the meds to me as soon as possible

Jody Griffith

The powder is easy to use. I learned quickly to be sure to mix it in very thoroughly to head off barfing. Need to find a 1/8 teaspoon measure for proper dosing. I VERY MUCH appreciated being able to place my order by phone as I never put my credit card info online! The fellow I spoke with was very helpful! I received my order very quickly. I’ll be using ThrivingPets again as my pets needs change. My vet recommended them.
