Under D influence.
While this article is
not referenced from a Medical Source maybe it shouldn't be here ?
But it certainly makes for an interesting read.
Taken from the
Observer Newspaper in the UK and written by
John Clarke..
Vitamin D appears to be more important for our health than previously thought,
so ensuring we produce enough over the winter months is a priority.
.
Not only do the darker winter months do little for our moods,
but the lack of ultraviolet (UV) rays also deprives our body of its major source of vitamin D
a nutrient we need principally to work in conjunction with calcium to produce strong bones and teeth.
The action of the sun's UV rays on our skin stimulates the body to produce its most active and effective form
of vitamin D, known as 1,25-dihydroxycholecalciferol,
but between the months of October and March, few UV rays reach us,
which means that to meet the necessary levels, our bodies have to rely both on vitamin D accumulated
during the sunny months and stored in the liver and body fat, as well as far less efficient dietary sources.
