Boron

Boron may support bone health and calcium metabolism, though essentiality remains unclear.

Definition

Trace mineral potentially involved in bone health, calcium metabolism, and cognitive function. Essentiality in human nutrition is not definitively established.

How it works

Boron appears to influence bone mineral density and calcium metabolism, with some evidence suggesting it enhances vitamin D status and calcium absorption. Research indicates boron may play a role in cognitive function and motor performance, though mechanisms are not fully understood. The mineral is present in all body tissues and is excreted primarily in urine. Boron's essentiality in human nutrition has not been conclusively demonstrated, though animal studies show deficiency can impair bone development and growth. Dietary boron intake varies based on food sources, particularly plant-based foods from boron-rich soil.

Role

May support bone health and calcium metabolism, though specific roles in human nutrition require further investigation.

Examples

  • Avocados
  • Almonds
  • Hazelnuts
  • Peanuts
  • Dried fruits
  • Leafy greens
  • Wine

Recommendations

No official requirement established; obtain boron from nuts, legumes, and fruits as part of a balanced diet. Supplementation is not recommended without specific medical indication or research-supported benefit.

Key takeaway

Boron shows promise for bone health support, though definitive nutritional essentiality in humans remains to be established.
