Have a healthy iron level.

Iron deficiency can have adverse effects on brain function, including attention and memory issues. Studies have shown that people who have low iron levels and took memory tests took longer to finish these tests, as well as scored significantly lower than people with normal iron levels. Thankfully, taking an iron supplement easily reverses these negative points. In that same study, people who took supplements scored at a normal level just a couple of months later.
