🌟 Wellness Fact Friday: Why Optimal Ferritin Matters 🌟
Ferritin is your body’s main iron storage protein. Think of it as the savings account for your iron supply. While hemoglobin tells us how much iron is actively circulating, ferritin reveals whether your body actually has reserves to keep your energy, hormones, and metabolism running smoothly.
🔹 Energy & Fatigue – Low ferritin is one of the most overlooked causes of fatigue, especially in women. Even with “normal” labs, suboptimal ferritin can leave you dragging.
🔹 Thyroid Health – Iron is required for the conversion of T4 → T3, the active thyroid hormone. Low ferritin can mimic hypothyroid symptoms (cold hands/feet, hair loss, weight gain).
🔹 Hair & Skin – Ferritin levels below ~70 ng/mL are linked to hair thinning and brittle nails, even if other labs look normal.
🔹 Hormone Balance – Iron deficiency stresses the adrenal system and can worsen PMS, perimenopause symptoms, and even mood swings.
🔹 Immune Support – Optimal iron storage helps your white blood cells function, protecting against frequent illness.
👉 Many people feel best when ferritin is between 70–100 ng/mL, even though the “normal” lab range is much broader.
✨ Bottom line: Ferritin isn’t just a number, it’s the foundation of energy, thyroid health, hair, and hormone balance.
