💗 LET’S TALK FERRITIN because “within range” doesn’t always tell the whole story.
Ferritin is essentially your body’s iron storage tank. When those stores get low, you may feel it before other labs become obviously abnormal.
You might notice:
• Exhaustion even after sleeping
• Brain fog
• Hair shedding or thinning
• Feeling winded easily
• Decreased stamina or weakness
• Headaches, dizziness or just feeling “off”
Here’s the important part: ferritin should never be interpreted by itself. Being within a lab’s reference range doesn’t automatically mean your iron status is adequate for YOU—especially if you’re symptomatic.
So why might ferritin stay low even while taking iron?
💗 Poor absorption: GI conditions, certain medications, bariatric surgery and digestive issues can interfere with absorption.
💗 Inflammation: Inflammation increases hepcidin, which can decrease iron absorption and limit how your body accesses stored iron. Ferritin can even look normal or elevated when inflammation is present.
💗 Ongoing blood loss: Heavy periods are a big one, but GI or other chronic blood loss may also need investigated. Replacing iron without asking where it’s going can miss the bigger issue.
💗 Iron does more than make red blood cells. It plays a role in oxygen transport, energy, neurological function and thyroid hormone metabolism. You can feel lousy from iron depletion even before significant anemia develops.
That’s why we look at the whole picture: CBC, ferritin, serum iron, TIBC/transferrin and transferrin saturation, plus additional testing when appropriate.
And there isn’t one magic “optimal” ferritin number for everyone. Symptoms, hemoglobin, iron saturation, inflammation, history and WHY your ferritin is low all matter.
✨ Bottom line: If you’ve taken iron for months and you’re still exhausted, foggy, winded or losing hair, don’t just keep switching supplements.
Ask WHY.
At Infuzed IV, labs are part of the story, not the whole story. Numbers + symptoms + history matter.
