Ferritin (Iron Stores)
The intracellular protein storing iron for red blood cell production.
Clinical Relevance
Ferritin levels indicate the body's total iron reserves. Low ferritin leads to microcytic anemia, impacting oxygen transport, cellular energy conversion, thyroid synthesis, and physical recovery.
Why It Varies
Varies due to dietary iron intake (haem vs non-haem), internal absorption barriers, blood loss, and systemic acute inflammation.
Longevity & Lifestyle Pointers
- Include iron-dense foods like dark leafy greens, lentils, or lean red meat in your diet.
- Pair iron consumption with Vitamin C (e.g. citrus fruits) to enhance absorption.
- Avoid consuming coffee, tea, or calcium supplements alongside iron-heavy meals.
Clinical Governance & Disclaimer
Extremely low ferritin indicates depleted iron stores. Unusually high levels can reflect systemic inflammation or iron overload (haemochromatosis), necessitating clinical signposting.
