Answer:
They lose blood every month during menstruation.
Step-by-step explanation:
Females of a reproductive age undergo menstruation, during which the uterine lining sheds every month, causing bleeding. This means their iron needs are higher than their male counterparts.
The lost blood needs to be replaced, which requires iron. Iron is an important part of hemoglobin, an important protein in red blood cells that helps in the transport of oxygen around the body.
Women who lose a lot of blood during their period are at higher risk of iron deficiency and may need to take iron supplements.
