We want to change the way iron deficiency is prevented and treated, and have brought to market innovative treatments for patients suffering from iron deficiency and iron deficiency anaemia.
Iron is essential for carrying and storing oxygen in our blood, for energy production, and for cell growth. Learn about the effects of iron deficiency on our health.
Iron deficiency is one of the leading contributors to the global burden of disease1. Iron is an essential nutrient that is normally acquired from food
Iron plays a vital role in the transport and storage of oxygen, in oxidative metabolism and in cellular growth. Iron is an essential building block for haemoglobin, a protein present in the red blood cells that carry oxygen from the lungs to the tissues and organs, where iron is needed to make energy.
Haemoglobin depends on iron for its formation and oxygen-carrying properties, and a lack of iron can cause a drop in the haemoglobin level and result in a condition called iron deficiency anaemia.
Iron deficiency is thought to be the most common cause of anaemia globally, although other nutritional deficiencies (e.g. folic acid and vitamin B12), inflammation, parasitic infections, and disorders that affect haemoglobin or red blood cell production, can also cause anaemia.
An estimated 2 billion people are anaemic worldwide, of whom more than 1 billion live with iron deficiency anaemia.

Iron is used to produce red blood cells, which help store and carry oxygen in the blood
If you have fewer red blood cells than normal, your organs and tissues will not get as much oxygen as they usually would
Iron deficiency adversely affects
Cognitive performance, behaviour and physical growth in children
Immune status and morbidity from infections in all age groups
Physical capacity and work performance in adolescents and adults
Untreated iron deficiency can lead to iron deficiency anaemia
Increased risk of hospitalisation and/or death in patients with iron deficiency, heart failure and chronic kidney disease
Anaemia is the most common and widespread nutritional disorder in the world.

Iron deficiency can be caused by a nutritional deficit of iron in the diet, by an underlying disease affecting the uptake and absorption of iron into the blood stream, or by substantial or recurrent blood loss. Furthermore, in a condition called functional iron deficiency, the body’s iron stores are not empty, but the release of iron from the stores is compromised.
The cells of the human body require iron for both mental and physical health, and when the body’s need for iron exceeds the supply of iron, the body becomes iron deficient.
Iron deficiency anaemia is prevalent in patients suffering from chronic inflammatory conditions such as heart failure, Inflammatory Bowel Disease and Chronic Kidney Disease

Iron deficiency is a prevalent medical disorder than can be caused by inadequate intake or absorption of iron from the diet. Increased iron loss, due to gastrointestinal or menstrual bleeding, or during surgery, can also contribute to iron deficiency. Another cause is an increased demand for iron, such as during pregnancy and childhood
The goal of treating iron deficiency is to replenish iron stores and normalise haemoglobin levels in anaemic patients. Initially, most patients are prescribed iron tablets. However, correcting iron deficiency with oral iron supplementation may take several months, and iron tablets are poorly tolerated by some patients. Therefore, if oral iron supplementation is ineffective or poorly tolerated, or if there is an urgent need to restore iron stores, patients may receive intravenous iron treatment
The underlying cause of the iron deficiency should always be considered, as this may require separate intervention. In some cases, it will be possible to cure the underlying cause and thereby prevent iron deficiency from re-occurring. In other cases, the underlying cause is not easily correctable, particularly in chronic conditions such as inflammatory bowel disease, heart failure or chronic kidney disease. These patients often require repeated iron treatment over many years
Because iron deficiency is frequently a consequence of other diseases and not the primary cause of the illness, it can often be neglected or underestimated
