Calcium: Benefits, Uses, Side Effects & Safety Guide

Calcium is an essential mineral commonly used to support bone health, teeth strength, muscle function, nerve signaling, heart health, and overall wellness. Learn what Calcium is, its potential benefits, common uses, side effects, safety considerations, and what current research says.

Because the body cannot produce calcium on its own, it must be obtained through food or dietary supplements.

Today, Calcium supplements are among the most widely used nutritional products worldwide and are commonly included in bone health and wellness formulas.
