Boron is a rare element extracted from the earth. It’s only found in nature combined with other elements as borate, borax or boric acid. Its method of action still requires further research, but it appears to help protect against calcium loss, and also activates oestrogen and vitamin D, which slow the demineralisation of bone. Research has therefore centred around its bone protective action, particularly in post-menopausal women.

Why do I need it?

In addition to boron’s role in bone health, it may play a role in blood pressure regulation due to its relationship to calcium metabolism. Abnormal calcium metabolism may lead to plaque formation on the artery wall, which attributes to atherosclerosis or ‘furred’ arteries.

Boron’s mode of action is still to be fully understood. However, it’s known that a diet rich in fruits and vegetables offers significant protection against osteoporosis and osteoarthritis – two conditions in which boron appears play a part. It also appears to have a beneficial effect on something called the parathyroid hormone which helps control calcium, magnesium and phosphorus balance – all minerals associated with healthy bones.

Best food sources

Although fruits (particularly dried fruits) and vegetables are generally the best sources, this does depend on having adequate levels in the soils, and unfortunately mineral levels are depleted in soil due to modern Western over-farming. Meat and dairy products are not high in this mineral because it doesn’t accumulate in tissue.

Five foods high in boron

Raisins – 4.5 mg per 100g
Almonds – 2.2mg per 100g
Avocadoes – 2.1mg per 100g
peanut butter
Peanut butter – 1.9mg per 100g
Lentils – 0.71mg per 100g

Are you getting enough?

Boron deficiency is becoming more of an everyday concern due to the Western diet. This can lead to an increase in bone-related diseases. Additionally, boron deficiency may be associated with an increased risk for postmenopausal bone loss in women.
