Low Iron can make your tired

16% of American women are low in iron. If your iron is depleted, everything just takes more effort. Iron deficiency and anemia are not the same thing. It is possible to be exhausted due to low iron and not be anemic.
Exercise uses up iron, so be especially on the lookout for low iron if you are ramping up your exercise.

 
Some symptoms of Low Iron:

  • Fatigue
  • Hairloss
  • Irratibility
  • Weakness

Foods High in Iron:

 
  • Chocolate
  • Liver
  • Sesame, sunflower and pumpkin seeds
  • Dried Apricots
  • Caviar
  • Clams, Mussels, Oysters
  • Red Meat

Just because you're not craving any of these foods doesn't mean your iron is good. The body doesn't always crave the specific foods it needs. For example, quite a few people who are low in iron love to chew ice. That doesn't have iron.

 
Before supplementing, have your doctor to do a blood test and see where your iron levels are

 
WARNING: An overdose of iron can kill. Too much iron is associated with cardiovascular problems. Get guidance from a doctor.
WARNING: Iron poisoning is the leading cause of poisoning deaths for children under 5 in the United States. Store any pills containing iron with appropriate caution.
