“Iron is also necessary to maintain healthy cells, skin, hair, and nails.”
Interestingly, many people are deficient in it despite the fact that it is found in many foods. The reason? It is hardly assimilated in the body, as the digestive system faces difficulty to extract it from the consumed food.

This fatigue affects brain function as well as the ability of the immune system to fight infections. In pregnant women, iron deficiency increases baby`s risk of being born earlier or smaller than normal.
