Could Your Iron Supplement Be Too Much of a Good Thing? Here’s How to Tell
A HuffPost health piece explains that iron deficiency is common and outlines how much iron to take (roughly 65 mg of elemental iron daily for deficiency, 27 mg daily during pregnancy). It notes that taking too much can cause constipation, upset stomach, and dark stools, and long-term iron overload can harm the heart or liver. The article emphasizes confirming iron deficiency with a blood test before starting supplements and consulting a doctor for personalized dosing, since fatigue has many causes and other conditions can mimic iron deficiency (e.g., thalassemia) and won’t respond to iron alone.
