This tablet supplement is formulated to add calcium, phosphorus, and vitamin D to the daily diet of dogs and cats. Each tablet is made from a blend of dicalcium phosphate, tricalcium phosphate, dried milk products, wheat flour, soy flour, brewers dried yeast, corn oil, and a vitamin D3 supplement for a flavor pets readily accept. The tablets can be offered by hand just before a meal or crumbled and mixed directly into food, allowing flexible daily administration. One bottle contains 60 tablets, dosed according to body weight. The formulation is intended as a nutritional supplement rather than a replacement for a complete diet, and a veterinarian can help determine whether added calcium supplementation is appropriate for a particular pet. Tablets should be stored with the bottle tightly closed to preserve freshness.
