I did a search and came up with a few threads on this, but nothing conclusive. Since its winter again here in Wisconsin, and already WAY too cold to expose any skin outdoors (plus I think we're too far north to actually have the sun close enough to make vitamin D at this time of the year). I have been doing a lot of research on the best way to get vitamin D, especially because of my location and the fact that I have multiple sclerosis which is linked to vitamin D deficiency.
From what I've learned, it seems that the best way would be to use tanning in a sunbed to make vitamin D. Now I just need to find somewhere that knows something about the UVA/UVB ratios that thier beds make! Apparently the "medium pressure" beds make a ratio more similar to the sun, and are best for D production.
I'd love to be able to find something I could afford to buy and use at home, but for now I think I'll just be using tanning salons.
Ideally, I'd just spend all summer outdoors to soak up enough to last me (since your body can store it) but I work full-time indoors (for now....) so I'm sure I didn't make enough over the summer to hold me over the winter.
What are your thoughts? What do other northern-living people here do for vitamin D in the winter?
