I recently read an article stating that dicalcium phosphate is an ingredient to avoid when buying dog food because it can not absorb water and may cause kidney stones. I was really worried because it’s in a few of the foods in my dogs rotation (Nutrience grain free and Valens pasture). I’ve noticed it’s not listed as a red controversial ingredient on the review of foods on this site. Does anyone have any thoughts or more information on this ingredient?
Also, does anyone know what tricalcium phosphate is or how it compares to dicalcium phosphate? I’ve noticed that ingredient is in a few of my dogs foods but could find a lot of solid info on that one.
My puppy and my senior dog eat a food with dicalcium phosphate. I’m studying towards a degree in animal nutrition (stopped trusting my vet … but that’s another story, hah), and what I’ve found is that dicalcium phosphate is safe.
Calcium and phosphate helps growing puppies (and older dogs with weakening bones develop stronger bones. It’s like calcium for humans. Phosphorus (in dicalcium phosphate) helps form bones and teeth, and it works with protein synthesis for tissue repair. Aka it’s great for pups with injuries.
Through that I know that dicalcium phosphate is safe. I have no experience about tricalcium phosphate though. I’ll ask at my next vet/animal nutrition course. That’s a good question. With my basic chemistry knowledge, it seems like it’s just a different isomer/combination for dicalcium phosphate but I’m really not sure.
Thanks! With so many varying opinions on dog food ingredients, its hard to figure out what’s true. Please keep me updated if you find any info on tricalcium phosphate.
Steve’s Real Raw dog food uses dicalcium phosphate in their beef formula. I reached out to ask them why they use it, since beef is high in phosphate, and ground bones should provide enough calcium. Two emails and a phone call was ignored. I stopped feeding my dog their raw food because they apparently don’t care about their clients, and they are certainly NOT transparent about their dog food ingredients. I will also add that the product was very inconsistent from batch to batch.
Oh, and Steve no longer owns the company. Perhaps this is when it all went south.
I personally stay away from any dog food containing dicalcium phosphate because research has shown it causes kidney stones.
