Hi folks:

This one says the typical older individual may need to supplement

with 1300 IU/day:

D deficiency.

Serum 25-hydroxyvitamin D3 [25(OH)D3] concentrations are currently

recognized as the functional status indicator for vitamin D. Evidence

is reviewed that shows that serum 25(OH)D3 concentrations of < 80

nmol/L are associated with reduced calcium absorption, osteoporosis,

and increased fracture risk. For typical older individuals,

supplemental oral intakes of approximately 1300 IU/d are required to

reach the lower end of the optimal range. Evidence of substantial

problems in routine clinical measurement of serum 25(OH)D3

concentrations among patients is cited. There is great need for

standardization and improved reproducibility and sensitivity of

measurements of serum 25(OH)D3 concentrations.

I don't get much sun in Maine in the winter, so I take 2000 IU/day.
