Zinc from animal sources, such as beef, pork, dark meat chicken, and some seafood, is absorbed best by the body. Good vegetarian sources include nuts, yogurt, beans, and fortified cereals.2

The daily recommendation for adults is between 8-11 mg daily depending on age and gender.3 Zinc deficiency can lead to frequent infections and illness, wounds that are slow to heal, hair loss, appetite loss, skin problems, and problems with taste and smell.1
