Glycerin
A humectant — it holds moisture and keeps foods soft and chewy, which is why it's common in soft treats, jerky, and soft-baked kibble. It's also mildly sweet. Glycerin is generally recognized as safe and is well tolerated; it's usually plant- or animal-fat-derived as a byproduct of making soap or biodiesel.

This application is intended for educational purposes only. Scores are generated using publicly available product information and are not veterinary advice. We are not veterinarians. Always consult your veterinarian regarding medical decisions.
A high score does not mean a product is right for your pet, and a low score does not mean it is dangerous. An individual animal can react to an ingredient that scores well here, and a product with a mediocre score may be exactly what your vet recommends.
The score reads ingredients one at a time. It cannot account for how ingredients interact with each other, with other products you use, or with your pet's medications and conditions. Two ingredients that are each fine on their own may not be fine together. A score is a starting point for questions, not a substitute for professional judgment.
