Iron is an essential mineral that plays a critical role in the human body. It is a key component of hemoglobin, the protein in red blood cells responsible for transporting oxygen from the lungs to tissues throughout the body.
Adequate iron intake is crucial for maintaining healthy energy levels and overall well-being. It supports physical performance, cognitive function, and is vital for the growth and development of children and adolescents. Iron also contributes to a strong immune system and helps regulate body temperature.

Vitamin C can enhance the absorption of non-heme iron, while substances like calcium or tannins in tea and coffee may reduce it.
Iron deficiency, the most common nutritional deficiency worldwide, can lead to iron deficiency anemia. Symptoms include fatigue, weakness, pale skin, and shortness of breath. On the other hand, excessive iron intake, particularly from supplements, can cause toxicity, leading to nausea, constipation, and in severe cases, organ damage.
Maintaining appropriate iron levels is important for health. While a balanced diet rich in iron sources can prevent deficiency, individuals with specific conditions or dietary restrictions may require additional assessment. The body's ability to regulate iron absorption helps prevent excess, but certain conditions can affect this balance.
