The calcium get into your body through Vitamin D.
<u>Explanation:</u>
In order to make the bones healthy, calcium and phosphorus is very essential. Calcium cannot be made by human body. The body only gets the calcium it needs, by means the food you eat, or from supplements. Vitamin D plays a major role in the absorption of calcium in human body. Calcium is a major mineral in a human body that helps in the proper working of body cells and nerves.
The quantity of the minerals like calcium, phosphorous,etc that are present in a segment of bone determines the density of bone. A percentage of 15 to 20 of calcium is absorbed from the diet that human intake. When the levels of vitamin D is low, there will be lower intake to calcium by gut. This causes the bones to become weaker.

Ions are formed when an atom gains or lose electron during a chemical reaction.
<h3>How ions are formed?</h3>
Ions are formed by the addition of electrons or the removal of electrons from an atoms or molecules by the combination of ions with other particles. Ions formation occurs during covalent bond formation and ionic bond formation between different molecules. Those substances that gains electron bears positive ion while on the other hand, those elements that lose electron forms negative ion or charge on the atom.
So we can conclude that ions are formed when an atom gains or lose electron during a chemical reaction.
