Introduction: Understanding Calcium and Bone Health
As the most prevalent mineral in the human body and the main component of bones and teeth, calcium and bone health are intimately related. Bones that are weak and brittle due to a lack of calcium are more susceptible to fractures and diseases like osteoporosis.
All age groups, but particularly youngsters, postmenopausal women, and older persons, must maintain adequate calcium levels through diet and lifestyle. Everything you need to know about calcium and bone health is covered in this guide, including the best foods and supplements that are high in calcium, how to recognize the symptoms of a deficiency, and how vitamin D is essential for calcium absorption.
Why Calcium Is Essential for Calcium and Bone Health
Although 99% of calcium is retained in bones and teeth, it supports a wide range of bodily processes. Calcium is used by the body to:
- Maintain bone density and strength
- Support muscle function and nerve signaling
- Aids in hormone release and enzyme function
Your body takes calcium from your bones when you don’t get enough of it, which eventually causes your bone density to decline.
Daily Calcium Requirements by Age and Gender

| Teens (9–18 years) | 1,300 mg |
| Adults (19–50 years) | 1,000 mg |
| Women 51+ / Men 71+ | 1,200 mg |
| Pregnant/Lactating Women | 1,000–1,300 mg |
