Background. For older adults, serum 25-hydroxyvitamin D (25(OH)D) higher than 75 nmol/L lowers fracture risk and attainment of this 25(OH)D target may require 125 mcg (5000 IU)/d of vitamin D3.

Objective: We wanted to characterize the safety and efficacy of fortifying bread with a biologically meaningful amount of vitamin D3.
