Iron is an essential nutrient required for various physiological functions, including oxygen transport and DNA synthesis. However, the safety of iron supplementation, whether through dietary fortification, oral supplements, or intravenous (IV) administration, has been a topic of extensive research. This synthesis aims to provide a cohesive overview of the safety of iron based on multiple research studies.
General Safety of Iron EDTA:
Safety of Lower-Dose Iron Fortification:
Intravenous Iron Safety:
Risks of Excessive Iron Intake:
Novel Iron Supplementation Strategies:
Iron Doping in Nanoparticles:
The safety of iron supplementation varies depending on the form and dosage. Iron EDTA and lower-dose iron fortification in foods are generally safe. IV iron therapy, especially with newer formulations, is also safe but may cause infusion reactions. However, excessive iron intake can lead to serious health issues, emphasizing the need for careful management of iron supplementation. Novel iron compounds and delivery methods are being explored to minimize adverse effects and improve safety.
