Symtoms of low Iron

Too loaded a question. If we list the symptoms, and you have them, there's plenty of other conditions besides low iron that you could have. Fatigue is the most common one, and that could be a sign of countless things wrong.

That being said, iron DOES tend to be low in too many people, especially pregnant women. But you really should have a regular blood panel done before taking anything other than a multi-vitamin with minerals or water soluble vitamins.
