I found it googling:
"...the biological activity of 1 mcg is equal to 40 IU..."

I edited my original post to correct the numbers. I'm used to unit conversions, but only for engineering!

That is a translation from IU, but I can't remember what! Something about nmol/L... IIRC. Which I probably don't.

Is mug the same as mcg (ie greek letter mu)? So 10-15 mug/d would be 400-600 IU supplemental vitamin D/day?

Vitamin D Supplementation & Reduced Risk of PE

...Considering only the intake of vitamin D from supplements, we found a 27% reduction in risk of preeclampsia (OR= 0.73 [0.58-0.92]) for women taking 10-15 mug/d as compared with no supplements. No association was found between intake of vitamin D from the diet alone and the occurrence of preeclampsia. CONCLUSIONS:: These findings are consistent with other reports of a protective effect of vitamin D on preeclampsia development. However, because vitamin D intake is highly correlated with the intake of long chain n-3 fatty acids in the Norwegian diet, further research is needed...

So they only looked at women with no prior pregnancies, and they asked about their diets and whether or not they were supplementing vitamin D, and found a 27% reduction in risk of PE in the population supplementing with vitamins.

As always, ask your docs before you supplement -- this is very similar to the preliminary data on C and E, but those turned out not to help in the bigger studies, and the women who supplemented got sicker, quicker.
