Make sure the iron supplement you take passed our tests and is right for you! Isn't your health worth it?
Although only one iron supplement failed to pass our recent tests (due to lead contamination), we identified major differences among popular iron products. For example, among those that passed testing and offer the best quality iron, the cost to get 25 mg of iron ranged from just two cents to over two dollars -- over 100 times the lowest cost!   Differences were also found in the dosage and forms of iron products provided. 

Iron is required to prevent and treat anemia. Iron deficiency is most common in menstruating women but also is commonly seen in children, pregnant women, and among people taking drugs that reduce stomach acid. Even mild iron deficiency may cause fatigue and impair learning, memory, and sports performance. Individual needs for supplemental iron vary and some forms may be better-tolerated than others. 

You must jointo get the full test results to help you choose the best iron supplement. You will get results for 12 supplements selected by and for 8 others that passed voluntary certification testing, as well as information about three supplements similar to one that passed testing.
