Bone Calcium

Essential mineral forming the structural basis of the skeleton.

Definition

Calcium is the primary mineral constituting the structure and rigidity of bones and teeth, accounting for approximately 99% of total body calcium.

How it works

Bone calcium is stored in the mineral matrix of bones, giving them solidity and density. The body maintains a strict equilibrium of blood calcium by drawing from bone reserves if dietary intake is insufficient. This regulation is crucial as calcium participates in numerous vital functions (muscle contraction, nerve transmission). Chronic calcium deficiency gradually weakens bone structure and increases the risk of fractures.

Role

Ensures the mineralization and solidity of bone and dental structure.

Examples

  • Milk
  • Cheese
  • Yogurt
  • Almonds
  • Broccoli
  • Canned sardines
  • Curly kale

Recommendations

Consume 1000 to 1200 mg of calcium per day depending on age. Vary food sources and associate calcium with vitamin D for better absorption. Limit caffeine and salt intake, which can increase urinary losses.

Key takeaway

Regular calcium intake is essential for building and maintaining a solid skeleton throughout life.
