Calcium Intake Calculator

Historical Background

Calcium is a vital mineral for human health, particularly in building and maintaining strong bones and teeth. Its significance has been recognized since ancient times, with historical records showing the use of calcium-rich foods for health. However, it wasn't until the 20th century that researchers began to understand the specific roles of calcium in bodily functions, including muscle contraction, nerve signaling, and blood clotting.
