"Ferrous sulphate is an iron preparation.
Iron is a vital component of haemoglobin (oxygen-carrying
pigment of red blood cells) and is therefore important
in the formation of red blood cells. It is also
a component of myoglobin, a pigment which stores
oxygen in muscles for use during exercise. Iron
is an essential component of several enzymes and
is involved the uptake of oxygen by the cells
and the conversion of blood sugar to energy."
