Ferritin

Definition

Ferritin is a protein for storing iron found in the blood, reflecting the total body iron stores. Serum ferritin levels indicate the risk of iron deficiency.

How it works

Ferritin is the primary indicator of the total body iron stores, essential for producing hemoglobin and transporting oxygen. Low levels may indicate iron deficiency, potentially leading to anemia. Elevated levels may indicate iron overload or inflammation. It also increases in cases of infection, inflammation, or liver disease.

Role

Storage and transport of iron, essential for cellular respiration and oxygen transport.

Examples

• Meat
• Liver
• Eggs
• Lentils
• Chickpeas
• Spinach
• Dried fruits

Recommendations

Regularly consume iron-rich foods (meats) and non-heme sources (legumes, fortified cereals) paired with vitamin C to enhance absorption. Regular blood tests are recommended in cases of persistent fatigue.

Key takeaway

Ferritin reveals the status of iron stores and guides nutritional and medical interventions.
