Does Sunscreen Cause Vitamin D Deficiency?

One of the most common reasons people give for skipping sunscreen is a fear of vitamin D deficiency. It is a fair question, so here is what the research actually shows.

What the research found

A systematic review examined whether sunscreen use lowers vitamin D. It found that while sunscreen can reduce vitamin D production under controlled experimental conditions, real-world sunscreen use has not been clearly shown to cause vitamin D deficiency (Neale et al., 2019, PMID 30945275). In everyday life, most people do not apply enough sunscreen to block all UV, and incidental sun exposure continues throughout the day.

What this means for you

You do not have to choose between protecting your skin and maintaining vitamin D. Deliberately skipping sun protection is not a reliable or safe way to raise vitamin D, since unprotected sun exposure increases the risk of skin ageing and skin cancer. If you are concerned about your levels, diet and supplements are a safer route.

  • Keep wearing daily broad spectrum sunscreen.
  • Get vitamin D from food and, if needed, a supplement.
  • Ask your doctor about testing and supplementation if you are worried.
