Have you ever got a chance to donate blood or plasma to any blood center due to low iron levels? Most of the donors know that their iron levels have to be kept at a healthy level to donate blood, but they don’t usually understand why healthy iron levels are important.

Let’s make it simple. Iron is an important component of hemoglobin, the substance in red blood cells that carries oxygen from your lungs to transport it in your body. If you don’t have enough iron, your body can not make enough healthy oxygen.

 “Every cell in the body needs iron,” says Dr. Reed E. Drews, associate professor of medicine at Harvard-affiliated Beth Israel-Deaconess Medical Center. “Even though the hemoglobin may be at a level sufficient to deliver oxygen to the tissues, you need iron for other things—for example, in your muscles and brain cells.”

Iron and Anemia

Not having enough iron is called Anemia. If someone who has suffered from severe anemia knows that it can be a challenge to maintain a normal life while getting your iron stores to where they should be.

Iron is an essential mineral that plays a critical role in transporting oxygen around the body. When we eat food with iron, iron is absorbed into our body, mainly through the upper part of our small intestine. Iron also helps to keep the immune system healthy. Eating a balanced, healthy diet, including good sources of iron, helps to prevent any deficiencies.
