Wrought Iron
Wrought iron is an iron block obtained by solid reduction of iron ore at a lower smelting temperature in ancient times, also called forged iron. In Southwest Asia, from 1200 BC to 1000 BC, the use of wrought iron has reached a certain scale. In 800 BC, the smelting method spread to Central Europe, and it spread to England in 500 BC.

Iron
Iron is a major component of hemoglobin, a type of protein in red blood cells that carries oxygen from your lungs to all parts of the body. Without enough iron, there aren't enough red blood cells to transport oxygen, which leads to fatigue. Iron is also part of myoglobin, a protein that carries and stores oxygen specifically in muscle tissues.
