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

What does it do?

Silicon has two main functions. It:

  • helps keep bones healthy

What happens if I take too much?

There isn't enough evidence to know what the effects might be of taking high doses of silicon supplements each day.

What is our advice?

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

Taking 700 mg or less of silicon supplements a day is unlikely to cause any harm.
