Boron

Also known as: B

Boron is a trace element that probably influences the metabolism of calcium, magnesium, vitamin D and sex hormones. It is not recognised as an essential nutrient and evidence for supplements is still limited.

What it is used for

  • Bone health support – weak evidence
  • Relief of joint pain in osteoarthritis – weak evidence from small studies
  • Raising free testosterone – weak evidence from small short-term studies

Forms and how they differ

boron citrate, glycinate, aspartate

common supplement forms, differences between them are poorly studied

calcium fructoborate

form naturally found in plants

the manufacturer should state the form; without it quality is hard to judge

When to take it

Once daily with food.

Pairs well with

Calcium, magnesium, vitamin D.

Do not combine / separate

Watch out for

In pregnancy, while breastfeeding, with kidney disease and hormone-sensitive conditions do not use without consulting your doctor.
