Dr. Holick explains if people living north of Georgia will be able to absorb enough vitamin D from the sun during the winter season.

Dr. Holick:
Well in the wintertime, of course, you wear more clothing. The sun’s rays are weaker, but when we did a study, we found that you have to live below Atlanta, Georgia to be able to make any significant vitamin D in your skin in the winter time. So basically if you live above Atlanta, Georgia, you cannot make vitamin D in your skin from November through February. If you live above New York City, you can’t make any vitamin D in your skin from about mid-October to almost mid-March to early April.
