Role Of Ferritin: What Is It And How Does It Promote Your Well-Being

Are you dealing with fatigue, hair loss and brittle nails and wondering what may be the cause? These signs may indicate low ferritin levels, a protein that stores and releases iron in your body. It is found primarily in your liver, spleen, and bone marrow, and acts as a reservoir, ensuring your body has access to iron when required. In this article, we explain its role in promoting your overall health and what happens if your ferritin level is not balanced.

What Is Ferritin?

Ferritin is the protein found inside cells that stores excess iron once the iron requirements of the cell have been met and releases it when there is an urgent need. For this reason, low levels of ferritin are a sign of iron deficiency. The highest concentrations of ferritin are found in the cells of the liver (hepatocytes) and immune system (reticuloendothelial cells).

Additionally, ferritin acts as a significant marker of the cellular redox balance, which can be disrupted in various diseases, such as chronic inflammation, metabolic disorders, and cancer. Elevated ferritin levels, along with other markers of inflammation, have been consistently linked to higher disease severity and increased mortality rates.

According to a 2008 study, ferritin levels greater than 200 ng/mL in women and 300 ng/mL in men are considered abnormal.

Symptoms of Low Ferritin Levels

Watch out for these signs to find out if you have low ferritin levels in your body:

• Fatigue
• Weakness
• Pale skin
• Dizziness
• Shortness of breath
• Rapid heartbeat

Symptoms of High Ferritin Levels

Just like low ferritin levels are harmful to your body, similarly high levels can lead to these health issues:

• Fatigue
• Joint pain
• Abdominal pain
• Heart problems
• Unexplained weight loss
• Body hair loss
• Changes in sex drive

Causes of Low Ferritin Levels

• People with iron deficiency have low ferritin levels. This happens when your diet does not contain enough protein.
• Anaemia is another reason why you may have low ferritin levels. This happens when you don't have sufficient Red Blood Cells (RBCs) for attaching iron.
• Other causes may include excessive menstrual bleeding, internal bleeding, and stomach conditions affecting intestinal absorption.

Causes of High Ferritin Levels

Here are some conditions that may increase the ferritin levels in your body:

• Hemochromatosis
• Rheumatoid arthritis
• Hyperthyroidism
• Type 2 diabetes
• Iron poisoning
• Leukaemia
• Restless leg syndrome
• Hodgkin's lymphoma
• Liver disease

Why Is Ferritin Important For Your Body?

Keeps Your Energetic

Ferritin contains iron which helps in maintaining energy levels in your body. It helps your cells produce Adenosine Triphosphate (ATP), which is also known as the energy currency of your body. Having adequate ferritin levels helps your muscles and tissues receive enough oxygen to function effectively, preventing fatigue and lethargy.

Boosts Immunity

Ferritin takes care of the iron supply in your body, which is important for maintaining a healthy immune system. It helps your body fight infections and recover quickly from illnesses. On the other hand, low ferritin levels can compromise your immunity, making you more susceptible to infections.

Promotes Brain Health

Iron is important for maintaining cognitive function and neurological health. It facilitates the production of neurotransmitters like dopamine and serotonin, which regulate mood, focus, and emotional well-being. By maintaining adequate ferritin levels, you support brain function and mental clarity.

Promotes Healthy Skin, Hair, and Nails

Iron is essential for collagen synthesis, a protein that keeps your skin elastic and resilient. Ferritin levels also influence hair growth and nail strength, as these tissues rely on an adequate iron supply for regeneration and repair.

Enhances Athletic Performance

For athletes or individuals who engage in regular physical activity, ferritin is particularly important. It ensures your muscles receive the oxygen they need during exercise, preventing fatigue and improving endurance.
