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.
