Chicken liver is a source of choline, an essential nutrient intrinsic to cell functioning, brain and nerve activity, liver metabolism and nutrient transportation. The Institute of Medicine recommends most adult women consume at least 425 milligrams of choline daily and men, 550 milligrams. A 3.5-ounce serving of chicken liver provides 294 milligrams of the nutrient -- just shy of half of a day’s worth. The iron in chicken liver is valuable as it is readily absorbed by the body, making it a good food to add to the diets of people with pernicious anemia.

Cholesterol Concerns

Although chicken liver has many nutritional virtues, it does contain a very high amount of dietary cholesterol. A 3.5-ounce serving contains 564 milligrams of cholesterol -- almost two times the daily limit recommended by the American Heart Association. If your doctor has diagnosed you with high cholesterol or you take cholesterol-lowering medication, consult your doctor before consuming chicken liver regularly.
