Calcium in the Body What does it do?

Calcium is a vital mineral that plays numerous roles in the human body beyond its well-known function in building and maintaining strong bones and teeth. It is the most abundant mineral in the body, and approximately 99% of the calcium found in humans is stored in the bones and teeth. The remaining 1% circulates in the bloodstream, where it is essential for various physiological processes. This small yet critical percentage is involved in muscle contraction, nerve transmission, hormone secretion, and blood clotting.

Without adequate calcium, these bodily functions can become impaired. For instance, calcium is crucial for the contraction of heart muscles, which pumps blood throughout the body. When calcium levels are low, the heart may not function efficiently, leading to complications over time. Additionally, calcium plays a role in regulating blood pressure. Studies have shown that calcium contributes to the relaxation of blood vessels, aiding in the maintenance of healthy blood pressure levels.
