What is Boron?
Boron is a trace element found in fruits and vegetables, but how much they contain depends on the soil they're grown in. Where the soil has enough boron, fruits and vegetables are the main dietary sources. The body only needs small amounts. Boron is not classed as an 'essential mineral' in nutritional guidelines.
What does the research say about Boron?
Even so, researchers have asked whether boron is nutritionally relevant and looked at what low boron status means for bones, brain function and the immune system.
Much of the interest in boron centres on how it interacts with other nutrients and hormones, particularly calcium, magnesium, vitamin D and oestrogen. That's why it often comes up in conversations about bones as we age, and for women around and after menopause.
One study in postmenopausal women looked at the effect of dietary boron on mineral, oestrogen and testosterone metabolism, including how much calcium and magnesium was lost in urine. Animal research has also looked at how boron interacts with vitamin D.
