This is one of the most common things we see: a woman coming in with fatigue, hair loss, and brain fog who's been told her labs are completely normal.
Nine times out of ten, nobody checked her ferritin. Serum iron and ferritin are not the same thing and ferritin below 50 ng/mL is directly linked to all three of those symptoms, even when everything else looks fine.
Standard labs don't flag ferritin as low until it drops below 12 ng/mL. We aim for 50 to 100. That gap is where a lot of women are living.
