About a year and a half ago I found out I had low vitamin D levels from a doctor. He recommended I get 20-30 min of sunlight exposure 2 to 3 times a week as well as taking a d3 supplement.
This seems to keep things normal until winter hits and I can't really get much sunlight, and if I do it's usually just my face. Living in the northern United States, the winter makes up most of the year and it's not very sunny more than 3-4 months out of the year.
I can take d3 supplements during the winter, but to be honest I don't think d3 supplements are at all the same as the vitamin D made from sunlight and I don't notice much from taking them.
Moving somewhere else isn't really an option at the moment and I would rather not get vitamin D from tanning salons (it's very short term benefit vs long term possible problems).
Are there any other options out there anyone is aware of?
