What It Measures
The blood level of ferritin protein, which stores iron intracellularly and releases it in a controlled fashion.
Ferritin is the primary iron storage protein. It reflects total body iron stores and is also an acute phase reactant (rises with inflammation). Both high and low values are clinically significant.
Current Value
What High Means
Elevated ferritin may indicate iron overload (hemochromatosis), inflammation, liver disease, or metabolic syndrome. Excess iron is oxidative and damages organs.
Possible Symptoms
Joint pain, fatigue, abdominal pain, skin discoloration (if hemochromatosis)
What Low Means
Low ferritin indicates iron deficiency, the most common nutritional deficiency worldwide. Causes fatigue, weakness, hair loss, and impaired cognitive function — often before anemia develops.
Possible Symptoms
Fatigue, weakness, hair loss, pale skin, shortness of breath, restless legs, poor concentration
Risk Factors
Iron overload damage (high), anemia and fatigue (low)
Actionable Advice
Supplements
- •Iron bisglycinate (if low)
- •Vitamin C (enhances iron absorption)
- •Lactoferrin
Diet & Lifestyle
- •If high: donate blood regularly (most effective way to lower ferritin)
- •If low: pair iron-rich foods with vitamin C
- •Avoid tea/coffee with iron-rich meals (inhibits absorption)
- •Test ferritin alongside iron, TIBC, and iron saturation for complete picture
- •Consider hemochromatosis genetic testing if persistently elevated
