Question: are eggs rich in vitamin d?
Answer: Egg yolks One typical egg yolk contains 37 IU of vitamin D, or 5% of the DV ( 7 , 24 ). Vitamin D levels in egg yolk depend on sun exposure and the vitamin D content of chicken feed. When given the same feed, pasture-raised chickens that roam outside in the sunlight produce eggs with levels 3–4 times higher ( 25 ).
