Ferritin: The Hidden Marker Behind Fatigue and Low Energy
Ferritin measures the body's stored iron levels and is one of the most important markers when investigating fatigue.
Iron plays a central role in transporting oxygen around the body. When iron stores fall, the body's ability to produce healthy red blood cells declines.
Ferritin testing can identify iron deficiency long before anaemia develops.
Why Ferritin Matters
Iron supports:
- Oxygen transport
- Energy production
- Cognitive function
- Muscle performance
Low ferritin can lead to iron deficiency anaemia, one of the most common nutritional deficiencies worldwide.
Why Iron Deficiency Is Common
Menstruation Regular menstrual blood loss increases risk.
Pregnancy Iron demand rises significantly.
Diet Low intake of iron-rich foods.
Endurance training Athletes may experience increased iron loss.
Symptoms of Low Ferritin
- Extreme fatigue
- Hair thinning
- Pale skin
- Shortness of breath
- Reduced exercise tolerance
- Restless legs
Should Everyone Take Iron Supplements?
Iron supplementation should only be undertaken when deficiency is confirmed, as excessive iron intake may be harmful.
Testing helps guide appropriate treatment.
Who Should Consider Ferritin Testing?
- Women with heavy periods
- Individuals experiencing persistent fatigue
- Endurance athletes
- Vegetarians and vegans
