Calcium: Benefits, Uses, Dosage & Complete Guide

Calcium is the most abundant mineral in the human body and is essential for maintaining strong bones, healthy teeth, muscle function, nerve signaling, and normal blood clotting. Nearly 99% of the body's calcium is stored in bones and teeth, while the remaining amount supports many vital physiological processes.

Calcium is naturally found in dairy products, leafy green vegetables, fortified foods, nuts, and seeds. It is also widely available as a dietary supplement in forms such as Calcium Carbonate, Calcium Citrate, Calcium Lactate, and Calcium Gluconate.

As awareness of bone health and healthy aging continues to grow, Calcium supplements have become one of the most popular nutritional supplements in Pakistan for supporting bone strength, muscle function, and overall wellness.

What Is Calcium?

Calcium is an essential mineral required for healthy bones, teeth, muscles, nerves, and cardiovascular function. The body cannot produce calcium on its own, making it important to obtain adequate amounts through food or supplements.

When dietary calcium intake is insufficient, the body may draw calcium from bones to maintain normal bodily functions, highlighting the importance of consistent daily intake.

Why Is Calcium Important?

Calcium helps:

• Build and maintain strong bones

• Support healthy teeth
