Iron is a vital mineral with several crucial roles in the body. Here are five main functions:
1. Oxygen Transport and Storage:
Iron's primary function is in the production of hemoglobin, a protein in red blood cells responsible for carrying oxygen from the lungs to the body's tissues. This oxygen is essential for energy production and overall cellular function. Insufficient iron leads to anemia, resulting in fatigue and weakness due to reduced oxygen delivery.

2. Energy Production:
Iron plays a role in converting blood sugar into energy. It's a component of enzymes involved in the metabolic processes that generate energy from carbohydrates, fats, and proteins. [Reference provided in prompt]
3. Immune System Support:
Iron is crucial for a healthy immune system. It’s involved in the production and function of immune cells, helping the body fight off infections and diseases. [Reference provided in prompt, Spatone.au]
4. Cognitive Function:
Iron is essential for optimal brain function. It supports various cognitive processes, including memory, concentration, and problem-solving. Iron deficiency can negatively impact cognitive abilities, particularly in children and developing brains. [Reference provided in prompt, Active Iron]
5. Skin, Hair, and Nail Health:
Iron contributes to the overall health of skin, hair, and nails. While not its primary function, adequate iron levels support healthy growth and maintenance of these tissues. Iron deficiency can manifest in brittle nails and hair loss. [Reference provided in prompt]
