Iron is an essential nutrient for your body which you can get from your food. It is needed for your mental and physical health and to keep your energy levels up. Sometimes your body's demand for iron can outstrip supply, and this can lead to iron deficiency. Iron deficiency causes many symptoms including fatigue, dizziness, and shortness of breath. If you are experiencing symptoms it is important that you talk to your doctor so that they can investigate what is causing them. If tests show that your iron levels are low, your doctor may recommend iron therapy.
Why is iron so important for your health?
Iron is an essential nutrient for your body, which you get from your food. It is needed for your mental and physical health and to keep your energy levels up.1,2,3 Iron is present in a substance called haemoglobin, which is found in red blood cells. Haemoglobin carries oxygen in the blood from the lungs to the rest of the body.4 Oxygen is required in your brain for concentration and in your muscles for physical energy.5 Iron is also needed to maintain a healthy immune system, helping you to fight off infections.6
