It should be noted that it is also possible to consume too much iron; toxicity levels begin at about 45 milligrams per day. In an average diet it is very unlikely that cooking with cast iron will bring a person to this level. Low iron is more likely to be a problem, and cooking with cast iron can be less expensive and more fun (at least more hunger satisfying!) than taking iron supplements. If you do use cast iron you should consult your doctor before taking other iron supplements.
