• Vitamin B12: Duck eggs contain 168% of the daily value for vitamin B12 per 100 grams, whereas chicken eggs provide only 32%. Vitamin B12 supports red blood cell formation and neurological function.

• Iron: Duck eggs contain 20% DV for iron compared to 7% in chicken eggs. Iron carries oxygen throughout the body and supports immune function.

• Vitamin A: Duck eggs supply 23% DV for vitamin A versus 18% in chicken eggs. Vitamin A promotes eye health and immune function.

• Folate: Duck eggs offer 14% DV for folate compared to 9% in chicken eggs. Folate aids in cell growth and preventing neural tube defects during pregnancy.

However, chicken eggs contain more of certain proteins like ovalbumin which have antimicrobial and antioxidant properties. And when cooked, some nutrients like vitamin A decline more in duck eggs compared to chicken eggs.

Potential Health Benefits of Duck Eggs

• Heart health: Duck eggs provide omega-3 fatty acids that can improve cholesterol levels and lower heart disease risk.

• Eye health: More vitamin A promotes good vision and eye health.

• Weight loss: The extra protein may help curb appetite and support muscle mass during weight loss.

However, most of the research has involved animals or observational studies in humans. More rigorous controlled trials are needed to confirm these preliminary health benefits of duck eggs.
