Red blood cells (RBCs) are an important aspect of the human body. Not only does it carry oxygen from our lungs to the rest of our bodies, but it also releases carbon dioxide to your lungs for you to exhale. Our body depends on healthy iron levels in the body for the production of RBCs.
Having said that, insufficiency or deficiency of this vital mineral can often lead to a varied range of symptoms including fatigue and shortness of breath. This occurs because the body is no longer capable of producing blood cells central to carrying oxygen to different parts of the body.
Furthermore, low levels of iron in the body is also associated with a serious condition called anemia, which is why the state of deficiency is often called iron deficiency anemia.
