during the winter when living above and below approximately 33° latitude very little if any vitamin D3 can be produced in the skin from sun exposure. People who live farther North and South often cannot make any vitamin D3 in their skin for up to 6 mo of the year.41 For example in Boston at 42° North essentially no vitamin D3 can be produced in the skin from November through February. Inhabitants living in Edmonton Canada at 52° North, Bergen Norway at 60° North, or Ushuaia Argentina at 55° South are unable to produce any significant vitamin D3 for about 6 mo of the year
