Iron:
If your iron is low, in addition to iron rich foods, to bring it back up to normal quicker,
supplementing for 3+ months can be helpful.  
-Eating or drinking citrus or taking 250mg Vitamin C with your iron increased absorption
-Avoid taking your iron with cereals, dietary fiber, tea, coffee, eggs, or milk since they bind iron.
-Ferrous Sulfate 325mg (65mg elemental iron) by mouth once per day, or up to three times per
day is a standard recommendation; if it is too hard on your stomach, or causes constipation, you
can take the elemental iron equivalent in another formulation (it does make the stool dark, by the
way).
-Other Formulations: Slow FE, Gentle Iron, Iron citrate 23mg iron per cap, Ferrous fumarate,
Ferrous gluconate
-Overall dietary iron intake (in times of deficiency) is recommended to be 150-200mg.
Vitamins and Minerals:
In General, I don't feel like pills are a substitute for a healthy balanced diet of
food grown without toxins (pesticides), but sometimes in cases of certain
deficiencies or health conditions, supplementing with certain vitamins or
minerals is appropriate.
