Boron: The Ultra-Trace Element Gaining Serious Attention

Boron is not officially classified as an essential nutrient for humans, but accumulating research suggests it plays meaningful roles in bone metabolism, hormone function, and inflammation. It may influence how the body uses calcium, magnesium, and vitamin D.

Bone & Joint Research

Population studies have noted that regions with higher boron intake tend to have lower rates of arthritis. Boron appears to reduce urinary excretion of calcium and magnesium and may increase serum levels of 25(OH)D (vitamin D). Some researchers propose that boron's effects on bone health may be mediated through its influence on these established bone nutrients.

Food Sources

Raisins, prunes, avocados, nuts (especially almonds and hazelnuts), and legumes are among the richest food sources. A varied diet rich in fruits, vegetables, and nuts typically provides 1-3 mg/day.
