Iron is an important nutrient, as it allows oxygen to reach tissues. You may have more difficulty overcoming iron deficiency if you don't eat meat. Having enough iron in your system will prevent anemia and supplementing may support brain function and psychological resilience.



Since iron prevents anemia, it greatly contributes to the healthy maintenance of your brain, and improves certain functions in adolescent women. Research suggests that adequate iron supplementation can lessen the effects of depression and anxiety.


Iron deficiency leads to fatigue no matter what you do, it forces your body to work harder. Insufficient iron can cause symptoms such as irritability, fatigue, and difficulty concentrating. When your blood is iron-sufficient, however, you will feel more energetic and less tired.


Hemoproteins are proteins that contain heme that iron binds with porphyrin. Your red blood cells contain hemoglobin and myoglobin, two types of hemoproteins. As your heart, lungs, and brain need oxygen to survive, you develop anemia when your body cannot produce red blood cells that deliver oxygen to your tissues due to low iron levels.


Iron supplements can reduce the symptoms of menstrual anemia in women during and after their period.
