I had a specific question about vitamin D. I've seen the recent research from Scotland that shows low vitamin D levels affect MS severity and as I have asthma and all the bundle of horrid allergic diseases (as well as my LC) I've seen that asthmatic kids are low in vit D too.
So, I supplement now and again with a Vit D pill but I would like to know a decent dose to take on a regular, daily basis which will keep my vit D levels up. Can you take too much vit D and do you need sunlight to synthesise it and make it active? How much is a decent dose for a guy weighing 80kilos?
Thanks folks

Al,
At your latitude, you probably need a minimum of 5,000 or 6,000 IU daily, especially in the winter months, and more might be helpful for a while, in order to help boost your blood level of vitamin D. The proper blood test for vitamin D is 25(OH)D, (pronounced 25-hydroxy-D).
I take 5,500 IU daily in the winter, and my latitude is about 30, whereas yours is roughly 50, so you get far less sunlight than I. In the summer, I reduce my intake to 2,500 IU, but you might need more, due to the sun angle in the UK, (unless you get much more sun exposure time than average). Sunlight is not necessary to activate vitamin D in a pill, or liquid form - all you have to do is swallow it. That's why it's so helpful in the winter.
It is possible to overdose on vitamin D, but in order to do that, you would have to take something like around 40,000 IU every day, for several months. It's impossible to overdose on vitamin D from the sun, however, no matter how much sunlight you absorb.

It is suspected that some of the hardest material known to science can be found in the skulls of GI specialists who insist that diet has nothing to do with the treatment of microscopic colitis.
