NOW Foods Calcium Carbonate Powder 12 oz

NOW® Calcium Carbonate Powder supplies pure calcium carbonate, the form of calcium that contains the highest percentage of elemental calcium by weight, making it an economical way to support your calcium intake. Calcium is the most abundant mineral in the body and the primary structural component of bones and teeth, where about 99% of the body's calcium is stored. It's also essential for muscle contraction, nerve signaling and normal blood clotting. Because the body cannot make calcium and continually draws on its reserves, an adequate daily intake — from diet and, when needed, supplements — is important for building and maintaining a strong skeleton throughout life.* Because calcium carbonate is best absorbed in the presence of stomach acid, it's ideally taken with food. The pure, filler-free powder lets you adjust your serving and mix it into a beverage — a practical, budget-friendly option for meeting daily calcium needs.*

Keep it out of reach of children, store in a cool, dry place, and don't exceed the recommended serving. If you take a multivitamin or several supplements, review the combined amounts so you don't unintentionally double up on the same nutrient.
