Hi Keith ~

I've found Dr. Mercola's research to be of the most benefit, on each of these topics
regarding Vitamin D:

For myself, Vit. D is one of my top three "must have" nutrients as it links to so many physiological functions.  
I do not live in an area in which sunlight is readily available during the winter, so the supplement becomes even more important.  Vitamin K helps in its absorption.

Hope the link provides interest.

  Can we have contributions, please, from those of us who are concerned about vitamin D intake as to:

  (1) Whether you regard regular vitamin D intake is important enough to act upon

  (2) If you do, what do you do to boost your vitamin D intake during winter

  (3) Whether you regard the strategy you use to maintain your vitamin D levels as "paleo"?

  (4) What is your opinion and your experience of sun lamps?

  Incidentally, I checked the USDA nutrient analysis website with a view to comparing the vitamin D content of different foods and found it's simply not reported - at least in the foods I checked - which included raw wild salmon.
