Dangerously low Ferritin levels: What you need to know

If you’ve ever had a blood test, you may have seen the term ferritin. This is a crucial protein that stores iron, helping maintain healthy iron levels in the body. Low ferritin can lead to iron deficiency anaemia, affecting energy, immunity, and overall wellbeing. Regular testing allows early detection and timely intervention.

Our Protein & Ferritin (Iron Stores) Test offers a quick, accurate way to measure ferritin and protein levels. It can be included in our Vitamin and Mineral checks or added to your existing health assessment package.

What is ferritin?

Ferritin is a protein that stores and releases iron as needed. It helps regulate iron levels in the bloodstream, preventing deficiency or excess. Around 25% of your body’s iron is stored in ferritin, mainly in the liver, spleen, bone marrow, and immune cells.

Ferritin releases iron molecules, which bind to transferrin, transporting them to the bone marrow for haemoglobin production. Because dietary iron absorption can vary, ferritin ensures your body has reliable iron reserves.

Normal ferritin levels

Ferritin levels can vary by age, sex, and health status. Typical reference ranges for adults are:

• Female: 11-310 µg/L

• Male: 24-340 µg/L

Testing can identify both low ferritin (iron deficiency) and elevated ferritin (possible iron overload or inflammation).

Causes of low ferritin

Low ferritin is a sign of iron deficiency anaemia, which occurs when iron stores are depleted. Common causes include:

• Menstruation: Heavy periods can cause iron loss in women of reproductive age.

• Pregnancy: Increased iron demand for mother and baby.

• Gastrointestinal bleeding: From ulcers, bowel or stomach cancer, or NSAID use.

• Chronic kidney disease: Often linked to iron deficiency, requiring supplementation.

Symptoms of low ferritin

Signs of low ferritin can include:

• Pale skin

• Extreme fatigue and weakness

• Cold hands and feet

• Shortness of breath

• Rapid heartbeat

• Lack of appetite

• Brittle nails

• Sore tongue

• Headaches or light-headedness

How to increase ferritin levels

Correcting low ferritin involves treating underlying causes and supporting iron intake through diet or supplements.

Dietary sources

Haem iron (easily absorbed):

• Red meat

• Poultry

• Fish and seafood

Non-haem iron (plant-based):

• Nuts and seeds

• Beans and lentils

• Green leafy vegetables (e.g., kale, spinach)

• Whole grains

• Tofu

Supplements can help if diet alone is insufficient, especially for vegetarians, vegans, or those with absorption issues. Always consult a healthcare professional before starting supplementation.

Treating low ferritin

• Identify the underlying cause of deficiency

• Incorporate iron-rich foods into your diet

• Consider iron supplements if recommended

• Retest ferritin levels to monitor improvement

Regular monitoring ensures you maintain healthy iron stores and prevent recurrence.

FAQs

How do I know if my ferritin levels are low?

Low ferritin often shows as fatigue, weakness, pale skin, brittle nails, or shortness of breath. A blood test is the only way to confirm your levels.

Can low ferritin affect my energy and immunity?

Yes. Low ferritin can reduce red blood cell production, leading to fatigue, weakness, and a weakened immune response, making regular testing important.

Are ferritin tests included in other health checks?

Our Protein & Ferritin (Iron Stores) Test can be included in Energy Profile packages or added to most health assessment packages for a complete picture of your iron status.

How often should I check my ferritin levels?

Testing frequency depends on your iron status, health conditions, and risk factors. Your healthcare provider can advise, but regular checks are recommended if you have low iron or symptoms.
