Ferritin is a protein that stores iron in your body, releasing it when your body needs it. Think of it as your iron reserve. Free iron would be toxic for your body, so it’s bound by various proteins. Iron is mostly found in red blood cells. Some of these are bound to the protein transferrin, which carries them through the blood to the cells where they are needed, such as in hematopoiesis. The rest is stored in ferritin. When more iron is needed, ferritin releases it. Measuring your blood’s ferritin levels provides a clear indication of your body's iron stores.
When your ferritin levels are optimal, your body functions smoothly. However, when these levels drop too low or rise too high, it can lead to various health problems.
Low ferritin levels are commonly associated with iron deficiency, which is the most widespread nutritional deficiency worldwide. Symptoms of low ferritin include:
These symptoms occur because iron is essential for producing hemoglobin, the protein in red blood cells responsible for carrying oxygen throughout your body.
There are several reasons why ferritin levels might drop, including:
To diagnose low ferritin levels, your doctor will typically order a blood test. A ferritin level of less than 15 micrograms per liter is considered very low and often indicative of iron deficiency anemia.
If your ferritin levels are low, addressing the underlying cause and boosting your iron stores are essential. Here are some effective strategies:
While low ferritin levels are more common, high levels can also pose risks. Excess ferritin is often a sign of conditions like hemochromatosis (iron overload disorder), chronic inflammation, or liver disease. Symptoms of high ferritin include joint pain, fatigue, and abdominal discomfort.
If your ferritin levels are elevated, your doctor may recommend dietary adjustments, phlebotomy (blood removal), or medications to manage the condition.
Maintaining optimal ferritin levels is vital not only for physical energy but also for mental clarity and overall well-being. Low ferritin can disrupt your ability to function at your best, while excessive levels can damage organs and tissues.
If you're feeling tired, weak or finding it hard to concentrate, don't ignore it. You might have low ferritin levels, and getting that sorted can really improve things for you. Have a chat with your doctor and see what they can tell you. Getting your ferritin levels in check, whether that's through food, supplements or other medical options, is a great way to get healthier and feel better.
