Interventions

  • Vitamin D3 bioenhanced eggs — DIETARY_SUPPLEMENT
    Six vitamin D3-fortified eggs per week will be provided to participants to consume each week for 8 weeks
  • 25(OH)D3 bioenhanced eggs — DIETARY_SUPPLEMENT
    Six 25(OH)D3-fortified eggs will per week be provided to participants to consume each week for 8 weeks.

Study Details

The purpose of this research is to evaluate if 1) consumption of vitamin D3- or 25(OH)D3-biofortified eggs will increase vitamin D and 25(OH)D status in young adults who consume these bioenhanced eggs, 2) to determine if the gut microbiome profile is associated with 25(OH)D or vitamin D status and 3) to evaluate possible changes in the gut microbiome following an 8-week supplementation period providing 5(OH)D- or vitamin D bioenhanced eggs.
