Free-range eggs contain more vitamin E than their conventional counterparts. The "Mother Earth News" survey found triple the vitamin E in the eggs they tested, and Pennsylvania State University research found double the vitamin E in the eggs of grass-fed hens.

Omega-3s are connected to heart health, lowering cholesterol and blood pressure, and other potential health benefits such as decreased risk of diabetes, stroke, digestive disorders, rheumatoid arthritis, some cancers and dementia.

"Mother Earth News" reported the most modest differences, with the free-range eggs they tested containing only twice the omega-3s as conventional eggs, while the Penn State study found 2 1/2 times more.
