Question: Iron deficiency without anemia? I would just say that I would be wary of iron deficiency, even if it's not causing anemia, because iron plays roles in energy metabolism, detoxification, and thyroid metabolism separate from anemia. But the things that are easiest to test are thyroid panel and CBC. So if your thyroid panel and your CBC look great, you probably aren't truly iron deficient, but I would also measure it against symptoms. So for example, if you have unexplained fatigue and you feel much better when you get more iron in your diet, I would interpret that as iron deficiency, that probably is just most sensitively affecting the electron transport chain if it's not showing up in a CBC or a thyroid panel.
