This chapter underscores the potential of fortifying eggs with essential micronutrients to address widespread dietary deficiencies. It emphasizes the need to enhance nutrient intake in populations globally, summarizing recent research on enriching eggs with vitamins and trace minerals crucial for public health. A case study from a UK free-range egg brand illustrates successful vitamin D biofortification through academia-industry collaboration. The chapter also explores fortification with iron, zinc, selenium, and iodine, essential nutrients lacking in many populations. Biofortifying eggs presents a promising strategy to combat micronutrient deficiencies on a broader scale.
