Description: Ibandronic acid is commonly known as ibandronate sodium and is a bisphosphonate medication. Bisphosphonates are drugs that stop the breakdown of bone. By stopping the breakdown of bone, they allow the bone to rebuild stronger than before. Calcium helps build and maintain bones, while Vitamin D3 helps your body effectively absorb calcium to ensure proper absorption in just the right amount. Additionally, Vitamin D3 supports the muscles needed to avoid falls at elderly care facilities across the country. Research has shown an association between fall risk and low vitamin D levels.
