(4,035 posts)Apparently, about half off all Norwegians suffer from vitamin D deficiency, but are unaware. My physiotherapist told me she, a very healthy and health-conscious athlete, had only discovered it when she couldn't figure out why she was so tired all the time. When she got the results of blood tests back, they said they couldn't find anything, and when she questioned her vit D levels, they just said, pretty much everyone's level in our town is too low. It rains 255 days a year here, and is overcast another 80-100 depending on the year. Other parts of the country has no sun at all 4-6 months a year. So she started supplementing - as did I, after the summer, and I have yet to get my yearly cold/pneumonia. That is just anecdata, however, but I wish they would do studies on those with dark skin living at our latitudes, especially girls who wear hijab.
