A Dietary Intervention Study Examining the Effect of Consumption of Vitamin D-enhanced Eggs on Winter-time Vitamin D Status in Adults

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 55 (actual)
• Sponsor: University College Cork · Academic / Other
• Sex: All
• Age: 45 Years – 70 Years
• Healthy volunteers: Accepted

Summary

While there have been a considerable number of studies on the impact of additional vitamin D in the diets of hens on the resulting egg vitamin D content, the effect of consumption of such vitamin D-enhanced eggs on vitamin D status of healthy human subjects has not been tested in a RCT.

Detailed description

The aim of this study was to investigate the effect of consumption of vitamin D3 versus 25-hydroxyvitamin D3 biofortified eggs on winter serum 25(OH)D in adults using a 8-wk randomized controlled trial. This research will provide new data on the potential of vitamin D enriched eggs as a food-based strategy for prevention of vitamin D deficiency.
