boronResearch on the trace mineral boron is inconclusive, but it appears to play a vital role in the maintenance of bone health, prevention of bone loss and prevention of demineralization. Boron also appears to affect the metabolism of calcium, magnesium, copper, phosphorus,and vitamin D.


  • Helps to build and maintain healthy bones
  • Helps prevent bone loss and demineralization
  • Assists the absorption and utilization of calcium
  • Assist in the metabolism of vitamin D, magnesium and phosphorous

A recent study indicated that when boron was given to postmenopausal women they experienced a reduction in the loss of calcium, magnesium and to a lesser extent phosphorous through their urine.

In has also been found that people with arthritis have lower amounts of boron in their bones and synovial fluid when compared to people without arthritis.

Symptoms of Deficiency

At this time no symptoms of deficiency have been identified in humans. However, it should be noted that studies of animals have consistently found that a deficiency of boron resulted in stunted growth.

It has been suggested that 1 mg per day of boron is a reasonable amount to consume. People who eat adequate amounts of produce, nuts, and legumes are likely already eating many times this amount.
