From the Manufacturer:

Many people think that all calcium supplements are created equal. The truth is that the most common form of calcium supplement today is derived from limestone or rock. We don’t eat rocks as part of our balanced diet, so why would we choose to supplement our bone health nutritional needs with limestone? The calcium complex in Bone Strength Take Care is plant-sourced and whole-food.....not limestone.
