What Should I Do About My Low Vitamin D Level?

Key Information

  • Your vitamin D level is a little lower than recommended.
  • Start taking a daily vitamin D supplement containing 25-50 micrograms (1,000-2,000 IU).
  • Do not take more than this dose unless Blithehale Medical Centre specifically advises you to.
  • In the UK, sunlight can help your body make vitamin D between late March and the end of September, but sun safety is still important.

How Much Vitamin D Should I Take?

Take a daily supplement containing 25-50 micrograms of vitamin D (also known as colecalciferol). This may also be shown on the packaging as 1,000-2,000 international units (IU).

You can buy vitamin D supplements without a prescription from pharmacies and most supermarkets.

What About Sunlight?

In the UK, the body can make vitamin D from sunlight between late March and the end of September. Short periods outside with forearms or lower legs uncovered may be enough, but cover up before your skin starts to burn.

Who May Need Vitamin D All Year Round?

Some people, including those over 65, people who are housebound and people with naturally dark skin, are advised to take a supplement throughout the year.

What Happens Next?
