One way to do that is to apply suncream on exposed areas of skin, as it protects from harmful UVB rays. Does suncream block vitamin D? Dr Majad explains that suncream helps filter out the sun’s harmful UVB rays, which coincidentally are the same rays that aid vitamin D production. He adds: "There is some evidence that sunscreen (SPF) can reduce the skin’s production of vitamin D from sunlight exposure, but the situation is more nuanced than often portrayed. “You could also speak to your doctor about whether taking a daily vitamin D supplement would be beneficial.”
