People with pale skin may need vitamin D supplements because they keep out of the sun, say UK researchers.
The study in 1,200 people found those with freckles, blue eyes or a tendency to get sunburnt had significantly lower levels of vitamin D.
The trial – set up originally to look at vitamin D levels in melanoma patients – found levels were generally low, but worse in those sensitive to the sun with vitamin D levels 2.61nmol/L lower than those who were non-sensitive.
Lead author Professor Julia Newton-Bishop, professor of dermatology at the University of Leeds, said: ‘Fair-skinned individuals who burn easily are not able to make enough vitamin D from sunlight and so may need to take supplements.
‘This should be considered for fair-skinned people living in a mild climate like the UK and melanoma patients in particular.’
