Reproductive-age females will benefit the most from iron supplement. During menstrual cycle women get to lose some amount of blood, they need more irons to replace the lost irons because the body uses irons to make extra blood for a woman and her baby too when the woman is pregnant. Iron also helps move oxygen from your lungs to the rest of the body and to the baby. Thus, getting enough iron can prevent conditions of too few red blood cells that can make a woman tired (a condition known as anemia).

Hair follicles, blood, etc.
