A deficiency of iron for normal body function is the most common nutritional disorder in the world. Iron deficiency is the main cause of anaemia and is associated with poor brain development and long-term impairment of behavioural and cognitive performance in children. Common symptoms of iron deficiency include pallor of the skin, eye and beds of nails, weakness, difficulty breathing, dizziness, headache, hair loss, dry or rough skin and cravings for non-food items such as ice, paper, dirt, or clay.
