Iron is an essential nutrient that is responsible for the production of red blood cells and transporting oxygen around the body. Maintaining your iron levels is important, especially for anyone suffering from anaemia, injuries that result in blood loss and women during their menstrual cycle. Low iron levels can cause tiredness and longer-lasting fatigue which can have an impact on your ability to concentrate. It also aids your body’s natural immunity, protecting against illness and infection, and can help repair damaged cells, tissue and organs.
