Iron is the major vehicle for oxygen to be transported in the blood to all parts of your body. Once oxygen is delivered to the target cells, it will be used to produce energy for your daily operations. Besides being an oxygen transporter, iron can keep you away from infections, build collagen and body protein.

If you have inadequate amount of iron intake for a long period of time, iron deficiency might occur. Iron deficiency is one of the leading causes to anemia. Symptoms include fatigue, weakness, feeling cold, pale skin, breathlessness, irritability and reduced physical performance. People who are most susceptible to iron deficiency include children older than 6 months old and toddlers, growing female adolescence, menstruating or pregnant women, and vegetarians.
