Iron Benefits, Sources and Iron Deficiency
The benefits of iron include producing red blood cells to carry oxygen around the body helping combat fatigue and supporting cognitive function. Find out the key sources and benefits of this essential mineral, along with the symptoms of iron deficiency.
Iron is an essential mineral that is vital for producing red blood cells, which carry oxygen around the body. It helps combat fatigue while supporting cognitive function, the immune system, physical performance and development of the body. A lack of iron results in tiredness and can lead to iron deficiency anemia.
Why is Iron Important?
Iron is an essential mineral that helps maintain healthy blood to carry oxygen around the body. It is needed to produce healthy red blood cells and for proper hemoglobin function. Hemoglobin is the protein inside red blood cells that carries oxygen from our lungs around to all parts of our bodies. It transfers oxygen in the blood to our tissues and organs, and then carries carbon dioxide from our organs and tissues back to the lungs. This helps the body to function properly providing oxygen to the muscles and brain to support energy levels, as well as physical and mental performance.
Iron helps combat fatigue, while supporting good cognitive function and the immune system. It is also needed for body growth and development.
A lack of iron can lead to iron deficiency anemia. With insufficient iron, there would not be enough red blood cells to carry oxygen around the body, which would result in fatigue and poor wellbeing.
Benefits of Iron

Iron Deficiency
Iron deficiency occurs due to inadequate iron intake, where the body does not absorb enough iron for its nutritional requirements. The most common causes of iron deficiency is not eating enough iron within the diet and not taking supplements.
As an essential mineral, iron is required for hemoglobin and to produce red blood cells to carry oxygen around the body. Without enough hemoglobin, our bodies including our muscles and tissues will not get enough oxygen and cannot function properly. This can lead to iron deficiency anemia.
Iron Deficiency Anemia
Iron deficiency anemia is characterised by the blood lacking enough healthy red blood cells to carry oxygen to the body’s tissues and muscles. This can leave you feeling weak, tired, short of breath and can lead to more serious health issues. Iron supplements can be used to help treat iron deficiency anemia.
Symptoms of Iron Deficiency
Iron is vital for good nutrition and wellbeing. The symptoms of iron deficiency include:
- Fatigue.
- Weakness.
- Shortness of breath.
- Lack of concentration.
- Irritability.
- Pale skin.
- Heart palpitations.
- Pale skin.
- Dizziness.
- Headaches.
- Hair loss.
- Dry skin.
- Poor physical and mental performance.
Vaccination
New research highlights the critical role of iron for vaccine efficacy, which is discussed in our recent article. The study shows that iron deficiency has been linked to impaired immunity from vaccines.
Iron Absorption
Vitamin C increases the absorption of iron within our bodies, which can help prevent iron deficiency. Adding foods high in vitamin C to the diet can help to enhance iron absorption. Foods rich in vitamin C include oranges, broccoli, spinach and kiwi fruit.
Sources of Iron
The sources of iron are the food in our diet and dietary supplements.
