Plasma 25-Hydroxyvitamin D, Vitamin D Binding Protein, and Risk of Colorectal Cancer in the Nurses' Health Study

In conclusion, prediagnosis levels of total, but not free or bioavailable 25(OH)D, were associated with lower colorectal cancer risk. Although our findings support an inverse association of vitamin D with colorectal cancer, this association does not appear to be due to the unbound or bioavailable fraction of circulating vitamin D.
