Vitamin D supplements do not prevent bone fractures in children,
finds study

A major clinical trial led by Queen Mary University of London
and the Harvard T.H. Chan School of Public Health has found that
vitamin D supplements do not increase bone strength or prevent
bone fractures in children with vitamin D deficiency. The
findings challenge widely held perceptions relating to the
effects of vitamin D on bone health.

. . .

Now remember this is a study of "1st-world" kids
THEY get plenty of the vitamin from a large variety
of sources, so extra serves no good purpose.

My mother was old enough to remember kids with RICKETS
in her school classes. That was long before "fortified"
anything however. The general medical advice at the time
was to make sure the kiddies got LOTS OF SUN so they'd
make their own v-D. Of course, later, a serious downside
to that advice was discovered as various skin-cancer
rates jumped. Of course in the 20s/30s the life expectancy
wasn't all that great, so people tended to die of other
stuff long before skin cancers got their chance.

In any case, this study says you shouldn't OD yer
kids on v-D - doesn't help, MIGHT even hurt in
some ways down the line.

Some kids have lighter, more frangible, bones as a
matter of natural variation. We always saw a few who
always seemed to have something in a cast and others
who could take massive impacts and never break anything.
I, fortunately, fell into that latter group - but it
was not because of extra v-D.

There MAY be something that CAN bring that more breakable
percent closer to average, but it's not v-D. Maybe a speck
more HGH or calcium-re-uptake adjusters ... ? In the end
though, natural variation means, well, "variation", in
all things.
