1. Foods Rich in Iron and B12

A vitamin or mineral deficiency, especially in women, is probably due to a lack of iron in their diet. Since poor oxidization in the bodily tissues, originating from inadequate levels of iron and B12, cause the blood to pool and clot in the vessels, the darkening of your under eyes are often one of the first symptoms of an iron and B12 deficiency.

The American Institute for Preventative Medicine recommends a diet rich in leafy greens, lean red meats (fish, oysters, beef, and poultry), as well as iron-fortified cereals (those containing wheat germ). This is especially for those lacking iron and B12, as well as patients diagnosed with anemia.
