Iron is a mineral found in the body and is present in almost every cell. A lack of iron can lead to damage to various systems of the body.
Symptoms such as fatigue, weakness, low moods and depression may also be associated with a lack of this significant mineral. Children should be tested from the age of one for iron deficiency, says an expert. Iron is also essential for the function of the neurotransmitters, which are responsible for controlling mood, movement, attention, memory and learning.
