my take away message is that it's not a breastmilk issue, but a
lifestyle issue.

but either way, there is a deficiency issue.  getting bogged down in
semantics helps no one.  i just got a nearly hysterical mom from a
mother who's 14 mo old infant was just dx'ed with rickets.  obviously a
few minutes of sun a few times a week wasn't enough in her latitude to
protect her.   and rickets is the *end* stage of d deficiency.

synthetic D has other uses, not normal D repletion.

mmm hmmm.   there is one case of an adult man taking a formulation with
faulty labeling and an error in processing.  he was taking something
like a million iu's d per day.  yes he did have toxicity.  yes he did
recover.

yes, too much D is toxic.  more is not better.  but sufficient is
mandatory for health, not optimal.

if you've read the vitamin D research, krispin sullivan's papers on D
and various others, you'd know that latitude, there simply isn't
sufficient D from sunlight exposure 6-9 mo per year.   and the amount of
skin that  needs to be covered to protect from exposure would be
prohibitive even if there was.
