Calcium is the most abundant mineral in the body. It is necessary for the formation of bones and teeth. It regulates heart rhythm, cellular metabolism, muscle coordination, blood clotting, and nerve transmission. Calcium can have a calming affect on the nervous system.
Calcium eases insomnia and helps regulate the passage of nutrients through cell walls. If you don’t get enough calcium from the food you eat, your body automatically takes the calcium needed from your bones. If this process continues for years, your bones will become weak and break easily.
