Minerals are important nutrients that many people do not get enough of in their diets. Vitamins are important, but they don’t actually “work” without minerals. Your body cannot manufacture minerals, which are important building blocks for your bones, teeth, tissues, muscle, blood, and nerve cells. Minerals also act as catalysts for many biological reactions in the body. Calcium and magnesium are very important minerals, and there are other dietary minerals that support specific body functions.
