Phosphorus

Essential mineral for bone health and energy production.

Definition

Phosphorus is an essential mineral that works with calcium to build and maintain strong bones and teeth. It plays a critical role in energy metabolism and cellular function.

How it works

Phosphorus is the second most abundant mineral in the body after calcium, comprising about 1% of total body weight. It exists primarily in the bones and teeth, where it works synergistically with calcium to provide structural integrity. Beyond skeletal function, phosphorus is vital for ATP synthesis, the primary energy currency of cells, and for DNA and RNA synthesis. It also acts as a buffer system maintaining blood pH within the narrow range necessary for survival.

Role

Phosphorus enables energy metabolism, supports bone mineralization, and maintains acid-base balance in the body.

Examples

  • Fish
  • Poultry
  • Eggs
  • Dairy products
  • Nuts
  • Seeds
  • Whole grains

Recommendations

Most people receive adequate phosphorus through a balanced diet. Ensure a proper calcium-to-phosphorus ratio (approximately 1:1) for optimal bone health. Limit processed foods which often contain excessive phosphate additives.

Key takeaway

Phosphorus is essential for energy and bone health, and most diets provide sufficient amounts through natural food sources.
