You can't. It's an inherited Anemia, common among people of mediterranean decent like Greeks, Italians. There are two levels, major and minor. The body does not have the ability to absorb and hold iron. With minor you might be fatigued, if anything. The thing to watch for is if you decide to have children test to make sure your partner is not positive, otherwise two minor (together) produce major in baby. It's a pretty common disorder however no amount of vitamins, foods, etc. can bring the iron levels up to normal.
