Ferritin – What is it and why is it important?

Ferritin is a protein that acts as an iron storage molecule in the body. It binds and stores iron safely and efficiently, preventing iron from causing damage to cells. The ferritin level in the blood provides an indication of the body's iron stores. When iron stores are sufficient, ferritin levels remain within the normal range. If iron stores decrease, ferritin levels also drop, which may be a sign of iron deficiency.

Why is ferritin measured?

Iron deficiency is one of the most common nutritional deficiencies in the world. Measuring ferritin helps detect iron deficiency at an early stage, before it leads to anemia. Symptoms of iron deficiency may include fatigue, paleness, shortness of breath, and headaches.

What is a normal ferritin level?

Ferritin levels can vary depending on age, gender, and individual factors. Generally, reference values for adults are 15–125 µg/l for women and 20–195 µg/l for men (Ferritin, plasma (P–Ferrit) - Terveyskirjasto). These ranges are indicative, and values near the lower limit may already suggest iron deficiency and possible anemia.

Low ferritin – What does it mean?

A low ferritin level indicates that the body's iron stores are depleted. Although low ferritin itself may not cause symptoms, it can be a sign of iron deficiency, which may lead to iron deficiency anemia.

Recommendation for iron supplementation

If your ferritin levels are low, it is important to consult a doctor or nutrition professional about the possible need for iron supplementation. Iron supplements can help restore iron stores to normal levels and reduce symptoms of iron deficiency.

Summary

Ferritin is a key indicator when assessing the body’s iron stores. Low ferritin levels may indicate iron deficiency, and in such cases it is important to seek guidance from a healthcare professional. Take care of your iron balance and listen to your body – it will tell you when something is missing.
