5 Reasons Why Iron is Important & 4 Risk Factors for Iron Deficiency

4) Iron in mitochondrial respiration

This is a very important nutrient for the mitochondria. Mitochondria are responsible for producing most of the energy used by our cells, and iron is essential for this process. Iron is also needed to create heme groups in these organelles and affects the production enzymes that regulate oxidation and reduction in mitochondria. There are several health problems associated with iron in the mitochondria. In iron deficiency, mitochondria are larger, losing their function in time. They are unable to produce new glucose and have a decreased cytochrome concentration.
