An iron deficiency can mean that you aren’t able to produce enough oxygen-carrying red blood cells — therefore your body struggles to transport oxygen to your brain, tissues, muscles and cells, leaving you feeling exhausted and weak.
2. Muscle function
Iron is needed for muscle movement because it helps store the oxygen in muscles that allows them to move and strengthen. About 70 percent of your body’s iron can found in the red blood cells of your blood called hemoglobin along with muscle cells called myoglobin. It accepts, stores, transports and releases oxygen.
3. Brain function
The brain is very dependent on oxygen for proper function. If iron is not present, the brain does not receive the oxygen it needs, resulting in poor memory, decreased productivity and apathy. Children with iron deficiency tend to become irritable, restless and are unable to pay attention in class. These symptoms typically disappear once iron levels are restored.
4. Healthy pregnancy
Pregnant women should consume more iron-rich foods than anyone else since not only do they require iron, but they also need to meet the needs of the fetus and placenta. Pregnant women’s iron needs are around 27 milligrams daily, and this is often covered in a prenatal multivitamin.
According to the world health organization, iron deficiency during a pregnancy can increase the risk of maternal and infant mortality, premature birth, and low birthweight.
Restless leg syndrome is a condition characterized by uncomfortable feelings in your legs, giving you a strong urge to move them in order to find relief. Low iron levels are known to play a role in the occurrence of restless leg syndrome.
