• More vitamins A, D, and E
• Increased antioxidants like lutein and zeaxanthin
• Slightly higher protein quality
What Doesn’t Change
All eggs — regardless of where they come from — still provide excellent protein, healthy fats, and essential nutrients. The differences show up more in micronutrients and fat composition, not basic protein content.
Bottom Line
Darker yolks often signal a more nutrient-dense egg thanks to a broader diet, not because the egg is “different,” but because the hen’s nutrition was. It’s a great reminder that what goes into the animal often shows up in the food we eat.
Have you noticed yolk color differences when cracking eggs at home?
