A whole-food product for your dog. Bovine Colostrum has a long history as a nutritional supplement, particularly in the Indian Ayurvedic tradition. Canadian Bovine Colostrum is not only nutritious, but it may support a healthy immune system, and normal cell growth and repair. Colostrum is a great source of IgA and IgG antibodies that may help support and build up a healthy immune system. Colostrum is dense with an ingredient called proline-rich polypeptide (PRP).
