About 99% of the calcium in your body can be found in your bones, so it makes sense that when you think bone health you think calcium supplements. Calcium is an important element in the building up and maintenance of healthy bones and teeth, but it’s also required for blood clotting and muscle contraction. If you’re looking to buy calcium supplements and notice that many of them also include vitamin D, it’s because vitamin D is needed for proper calcium absorption and utilization. SwansonVitamins.com offers a wide range of calcium supplements, including chewable calcium, gummy calcium vitamins, and even liquid calcium.
