Iron is essential for haemoglobin and myoglobin synthesis, oxygen transport, and mitochondrial electron transport. Iron deficiency is the world's most common nutritional deficiency — affecting over 2 billion people. Supplementation must be guided by blood tests; excess iron is pro-oxidant and harmful.
