Calcium is the primary mineral responsible for strong bones.* The body also uses Calcium for proper muscle contraction and nerve function, and obtains this Calcium mainly from the bones.* In addition, Calcium is involved with heartbeat regulation.* Because the body can’t produce Calcium, an adequate intake every day can play a role in maintaining strong, healthy bones.* Sundown Naturals® offers Calcium supplements in a variety of formulations, including tablets, caplets, and liquid-filled softgels. Our Calcium supplements are also available in combination with other bone nutrients, such as Magnesium, Zinc, and Vitamin D.* Depending on your age, an appropriate Calcium intake falls between 1000 and 1300 mg a day.
