An analysis of impact of iron on health

It is widely understood that a lack of or excessive exposure to certain elements has a negative impact on human health. Absorption, metabolism, and the degree of interaction with physiological systems are all factors that influence an element's impact. Iron has a role in a number of metabolic activities, including oxygen transfer, deoxyribonucleic acid (DNA) production, and electron transport, and is thus necessary for virtually all living species. However, since iron may produce free radicals, its content in human tissues must be carefully monitored, as too much might cause tissue damage. Iron metabolism disorders are among the most prevalent human illnesses, including a wide range of conditions with a variety of clinical symptoms, ranging from anaemia to iron excess, and potentially neurodegenerative diseases. We cover the most recent advances in iron metabolism and bioavailability research, as well as our current knowledge of human iron requirements, as well as the implications and causes of iron insufficiency. Finally, we go through preventive measures for iron insufficiency.
