Iron deficiency is the most common nutrient deficiency worldwide, particularly affecting women of childbearing age. Because the symptoms creep in slowly, a deficiency is often recognized late. Crucial for the diagnosis is the ferritin level – the most important marker for iron stores.
Why iron is so important
Iron is a central component of the red blood pigment hemoglobin and is therefore indispensable for oxygen transport in the body. If iron is lacking, every cell receives less oxygen – this explains the typical fatigue. You can find a detailed classification on our page Iron: Power for your body.
Symptoms of Iron Deficiency
- persistent fatigue and decreased performance
- paleness of the skin and mucous membranes
- hair loss and brittle nails
- concentration difficulties
- shortness of breath during exertion
- cracked corners of the mouth
Correctly interpreting Ferritin, Hemoglobin, and Co.
A low ferritin level indicates empty iron stores – often before hemoglobin drops and anemia develops. Therefore, ferritin is the most sensitive early marker. Women have a higher iron requirement due to menstruation; pregnant women, female athletes, and people with vegetarian or vegan diets are also more frequently affected. The German Nutrition Society provides reference values for daily iron intake.
Treating Iron Deficiency
Mild forms can often be balanced through diet: red meat, legumes, whole grains, and green vegetables provide iron; Vitamin C improves absorption, while coffee and milk inhibit it. In cases of pronounced deficiency, doctors prescribe iron supplements. Self-supplementation without measured levels is not advisable, as too much iron can be harmful.

Frequently Asked Questions
What Ferritin Level is Too Low?
Ferritin levels below approximately 15–30 µg/l are considered indicative of depleted iron stores; the exact assessment depends on the laboratory, age, and gender.
What are the first signs of iron deficiency?
Often first: fatigue, difficulty concentrating, paleness, and hair loss.
Who is particularly at risk?
Menstruating and pregnant women, endurance athletes, and people with a low-meat diet.
