Brief Summary:

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.

Condition or disease Intervention/treatment Phase
Vitamin D Deficiency Low Bone Density Dietary Supplement: Bread fortified with vitamin D3 and calcium Phase 1 Phase 2

Detailed Description:
Methods: In a single-arm design, 45 nursing-home residents consumed one bun/d that had been fortified with 125 mcg (5,000 IU) of vitamin D3 and 320 mg elemental calcium.
