What Are the Functions of Iron for Human Growth?

Iron is a trace mineral that is essential for health. Found naturally in oysters, meat, poultry, green leafy vegetables and legumes, iron forms part of the hemoglobin, the oxygen component of the blood. It is vital for human growth.

Oxygen Source

• Iron is used to produce hemoglobin, which is needed to transport oxygen in the body. The Mayo Clinic points out that iron deficiency can cause fatigue, weakness, and loss of appetite, which can slow down growth.

Energy Source

• According to the University of Maryland Medical Center, iron is involved in producing adenosine triphosphate (ATP), responsible for generating energy in the body. Energy is needed for growth.

Sustain Cells

• Iron is the central atom of the heme group, a metal complex that can bind to oxygen in the lungs and carry it to cells in the body. A lack of iron can generate cell death, according to Washington University. It follows that iron is important for sustaining cells.

DNA Synthesis

• Iron in the heme group is also responsible for DNA synthesis and cell division, needed to generate growth in the body.

Connective Tissue

• Washington University also points out that iron is needed to produce connective tissues in the body and some neurotransmitters in the brain. It also boosts the immune system.
