Dose response equations for Vitamin D

Graph of Predicted vs. observed serum 25-hydroxyvitamin D concentrations.

serum vitamin D ng/ ml in blood = (427.46(1+pigmentation grade)*10**-2 +(dose IU/day)*10**-2)/Body massindex,

that is: (430 * square root of (1+pigmentation grade) + square root of IU)/ Body massindex

pigmentation grade: 2 = light, 1= intermediate, 0 = dark),

body mass index = (weight lbs)(703)/(height inches)**2

Based on 198 people in NE US in Fall and Winter 2009-2010

from www.plosone.org 1 June 2010:Serum 25-Hydroxyvitamin D and the Incidence....  and in wiki page
