Just like you need your lungs to breathe in oxygen, you need your blood to deliver that oxygen to all of the cells throughout your body. Makes sense so far, right?
Iron is a part of that blood-oxygen delivery system, and without proper levels of iron, you may begin to feel the weakening effects of low iron: tired all of the time, pale, listless and irritable.
Each and every cell in your body needs oxygen to produce energy. Not just for exercise, but for everyday life: brushing your teeth energy, walking up the stairs energy, going to work energy, baking cookies energy.
When you have normal iron levels, you have enough energy in every one of your body cells. Without enough iron, your cells produce less energy.
How does iron help out? As oxygen moves from your lungs into the blood, iron helps your red blood cells to “grab” the oxygen and to carry it to all parts of your body. (Fun fact: Iron is the part of the hemoglobin molecule that makes blood red!)
Even if you take in enough dietary iron, you may still be vulnerable to iron deficiency if you have higher iron needs than other individuals. Individuals with greater iron needs may include:
