The correct answer is iron.
Step-by-step explanation:
A common type of anemia known as iron deficiency anemia, it is an ailment in which blood is devoid of appropriate healthy red blood cells. The prime function of red blood cells is to carry oxygen to the various parts of the body. The condition takes place due to insufficient iron in the body.
In order to treat iron deficiency anemia, iron supplements are prescribed. It is essential to consume them as suggested by the physician.

Various brands of oral iron supplements are provided over the counter like carbonyl iron, ferrous sulfate, and heme-based iron.
