What is Ferritin?
Ferritin is a protein that stores iron in your body, and measuring ferritin levels provides an indirect estimate of your iron stores. Low ferritin levels may indicate iron deficiency or anemia, the most common nutritional deficiency worldwide.
Why is Ferritin Important?
Iron is essential for energy production and oxygen transport in the blood. Abnormal ferritin levels can lead to fatigue, headaches, restless legs syndrome, heart problems, and developmental delays. Low ferritin can also weaken the immune system and reduce physical performance. Women, vegetarians, and those with certain conditions are particularly at risk for low iron levels.
Understanding Ferritin Levels
Ferritin levels vary by sex and lab, but the following are common ranges:
- Males: 24-336 ng/mL
- Females: 11-307 ng/mL
- Optimal range: 50-150 ng/mL (SiPhox Health)
Low ferritin (< 30 ng/mL) indicates iron deficiency, while very low levels (< 10 ng/mL) suggest iron deficiency anemia. Elevated ferritin may be related to inflammation, liver disease, or other serious conditions.
Maintaining Optimal Ferritin Levels
- For Low Ferritin: Increase iron-rich foods (e.g., fortified cereals, oysters) with vitamin C to enhance absorption. Avoid inhibitors like tea, coffee, and high calcium foods.
- For High Ferritin: Reduce intake of iron-rich foods and consider donating blood. Limit alcohol to protect liver health.
Consult a doctor if ferritin levels are abnormally high, as this may indicate conditions such as liver disease, infections, or cancer.
