the 44.5 is right in the optimal range.   though should they continue at 
that level and continue to test q 3 mo like they should, they may see it 
going up too high.

while i love seeing  'enough' D being used, i do know of many cases of D 
overdose with these huge amounts given over the long term.  in one case, 
it was being done under the supervision of a doctor with many of the doc 
pts.....testing by the lab was done *wrong* and while i can't give any 
identifying details about the case, we'll just say it was *a lot* of 
people.

D research is still so in it's infancy.....and breastfeeding infants 
were probably never meant to get sufficient D from breastmilk - but from 
sunlight.    It may be that for them to get their D from bmilk, moms 
levels over time would be 'too' high and would put  her at risk of 
actually loosing bone instead of maintaining it among the other issues 
of D toxicity.

big fan of D, but concerned when researchers are playing around with 
such large amounts on moms and nurslings
