Nursing-Home Residents Given Bread Fortified With Vitamin D3
Long-Term Effects of Giving Nursing-Home Residents Bread Fortified With 125 Micrograms (5000 IU) Vitamin D3 Per Daily Serving
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.
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.
Inclusion Criteria: Healthy seniors in an institution in Romania Exclusion Criteria: Known hypercalcemic or hypercalciuric disease
