How much do I need?

You should be able to get all the boron you need from your daily diet.

What does it do?

Boron is thought to help the body make use of the glucose, fats, oestrogen and other minerals, such as calcium, copper and magnesium, in the food we eat.

What happens if I take too much?

Taking high doses of boron for long periods of time may reduce fertility in men.

What is our advice?

You should be able to get all the boron you need by eating a varied and balanced diet. But if you decide to take supplements containing boron it's a good idea not to take too much because this could be harmful.

Taking 6 mg or less of boron supplements a day is unlikely to cause any harm.
