Iron is a mineral that makes up an important part of hemoglobin, the substance in blood that carries oxygen throughout the body. Iron also carries oxygen in muscles, helping them function properly. Iron helps increase your resistance to stress and disease.
The body absorbs iron more efficiently during pregnancy; therefore, it is important to consume more iron while you are pregnant to ensure that you and your baby are getting enough oxygen. Iron will also help you avoid symptoms of tiredness, weakness, irritability, and depression.
