Make sure the iron supplement you take passed our tests and is right for you! Isn't your health worth it?
Iron supplements can help to prevent and correct iron deficiency common in young women but also seen in children and among people taking drugs that reduce stomach acid. Iron supplementation may also reduce unexplained fatigue in women of child-bearing age, inhibit dry cough associated with ACE inhibitors, and reduce symptoms of restless legs syndrome in people with low ferritin levels.  

But choosing an iron supplement can be difficult: There are many different forms and doses of iron available, a wide range of prices, and some may be better manufactured than others.
