Reminder to supplement your Vitamin D
To make Vitamin D you need sunlight that contains UV B rays which can be blocked by clouds. Fewer and fewer of these rays reach the ground the further north you go. (It’s the UV A rays that age you the most and having enough vitamin A in the skin protects you from this.) In the States certain disorders such as multiple sclerosis and colon cancer became much more common the further you move up from the sunbelt in the south.
Here in the UK, Liverpool is about level with Edmonton in Canada (53 degrees north) where you can make little vitamin D for up to six months of the year. According to Dr Hypponnen’s study, Scottish people were twice as likely to be vitamin D deficient as those south of the border. Even in Boston – 42 degrees north – you won’t be able to make vitamin D from sunlight for four months from November to February and Boston is a bit south of Marseilles.
Even in summer in the UK you only really get enough UVB rays between about 10am and 2pm; just exposing your hands face and arms during that time gives you about 5 to 10mcg (200 - 400iu), which isn’t nearly enough for the new levels recommended by the government. To get those, the American experts are suggesting you need to expose 50% to 80% of your skin for about 20 minutes.
