What does iron do exactly?

Iron is needed in the body for the purposes of making blood. Furthermore, iron is important for producing haemoglobin. Haemoglobin is what lends blood its red colour. Without iron, haemoglobin can’t be made and metabolism won’t be possible in the body. Iron also helps in the formation of myoglobin. Myoglobin ensures that oxygen can be used for metabolism during muscle activity. An iron deficiency can lead to anaemia. Symptoms include getting tired more easily, having poor appetite and breathing more rapidly during limited exertion. If you feed your pet Yarrah food, then it will be getting enough iron.
