Most people know that calcium is essential for keeping your bones and teeth healthy, but what else is it good for? Additionally, calcium is a key mineral for keeping your muscles and cardiovascular system healthy.

Still, it is estimated that over 70% of us don't get enough calcium each day, and a calcium deficiency could lead to other problems that include muscle cramps, inability to sleep, or becoming increasingly stressed out.

Plus, a lack of calcium in your body will lead to your bones becoming weaker, and put them at an increased risk for fracture. The effects of a calcium deficiency could be minor or major, so it's important to know the signs of both.

• Abnormal heart rhythm
• Convulsions
• Dermatitis
• Mental confusion

Symptoms of a minor calcium deficiency
