“Grade point average (GPA) is a very easy measure of success and something everyone can relate to,” said study author Karsten Koehler from the University of Nebraska-Lincoln in the U.S.

“That’s something that resonates pretty well. It’s always nice to show an association that has a meaningful effect that translates into something everybody can apply,” Koehler added.

Iron helps the body with essential functions such as transporting oxygen in the blood. Iron deficiency is associated with fatigue, lower work capacity and poor academic performance.

Physical fitness is also known to influence overall health, cognition and learning. They analysed 105 women enrolled at Penn State and had an average GPA of 3.68.

The results indicate that women with the highest levels of stored iron had the highest grades.
