New study highlights importance of vitamin D supplementation in patients sensitive to the sun

A prospective longitudinal study published this year in the British Journal of Dermatology compared the differences in seasonal vitamin D levels between patients who are sensitive to the sun and healthy people.

Rhodes LE, Webb AR, Berry JL, et al. Sunlight exposure behaviour and vitamin D status in photosensitive patients: longitudinal comparative study with healthy individuals at UK latitude. Br J Dermatol. 2014; [Epub ahead of print]

The authors of the study wanted to know if people who are sensitive to the sun due to skin conditions like polymorphic light eruption, solar urticaria, or as a side effect from medications have lower vitamin D levels than people who don’t have these conditions. This population is frequently advised to avoid the sun and use sunscreen when they are outside.

  1. There have been many previous studies which have found that, no surprise, people who avoid the sun have low levels of vitamin D. See, for example: http://vitamindwiki.com/tiki-index.php?page_id=1867) What is more interesting are the many anecdotal reports of people no longer being photosensitive when they had vitamin D supplements. Wish that there was a study about that.
    By the way: Google Search for Photosensitive “vitamin D” gets 127,000 hits currently.

    Seems like those that are sun sensitive are most likely to get moles. This is probably from having low D levels from birth onward. Their skin goes into a type of hyperdrive to create more vitamin D than usual and viola, a mole.

    My sister and I have both noticed a greatly reduced sensitivity to burning from taking oral vitamin D supplements.

    At the risk of repeating myself, and I am sorry for those who have already read me a gazillion times on this matter?

    I am a skin level 2 redhead. I have tons of freckles…I am covered, really, from head to toe, in freckles. I used to burn. But not since raising my 25(OH)D level to 75 ng/ml. Now I can sit under direct sunshine (sans sunscreen) for hours and I just don’t burn. It’s true that I live in Connecticut, and our version of sunshine is weak. But still, I think it is important to note that I used to burn–and now I don’t burn at all.

    It’s my opinion that sun burning and sun sensitivity stem from a less than optimal vitamin D blood level.

    I aim to keep my level at the higher end of optimal.

    Be well.
