Zinc
Zinc is one of the most abundant minerals in the human body, only after iron. It can be found in every tissue and cell. Overall, iron plays a key role in the activity of more than 300 enzymes with many important functions, such as nerve processes, digestion, metabolism, and more. Although more research is necessary, previous studies have shown that taking zinc supplements would help alleviate ADHD symptoms in some individuals. You can also find this mineral in many foods, such as whole grains, beans, dairy products, red meat, poultry, and oysters. [6]
