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).
There are only 3 sites for intramuscular injections, most commonly the deltoid then the ventrogluteal, and lastly the vastus lateralis for infants. If the site is a "hard muscle" or when the muscle is in constant spasm, then an intramuscular injection should not be done. Other reasons why an intramuscular injection cannot be done on a specific site are (1) atrophied muscle on an emanciated patient (i.e. malnourished or cachectic patients), (2) skin infection overlying the muscle group, and (3) the dorsogluteal muscle as this can hit the sciatic nerve and cause paralysis and other neuropathy of the ipsilateral leg.
