Best Sources of Calcium: Top Foods for Strong Bones and Overall Health

 

Why Calcium Is Essential for the Body

Calcium is a vital mineral responsible for:

• Supporting muscle contraction and nerve signaling

• Regulating heart rhythm and blood clotting

Since the body does not produce calcium on its own, it must be obtained through diet or supplements.
