Ferritin Level and Iron Deficiency Anemia: What You Need to Watch For

If you’ve always felt tired, iron deficiency anemia could be the problem. One key indicator of this condition is the level of ferritin in your blood.

Knowing what your ferritin levels can tell you about iron deficiency anemia (IDA) is important for spotting the symptoms earlier on, before treating this condition.

In this blog post, we’ll quickly look into how ferritin helps diagnose and monitor iron deficiency anemia, and discuss why it is a key indicator for your health.

What’s The Link Between Ferritin and Iron Levels?

Ferritin and iron levels are closely linked, as ferritin is a protein that stores and releases iron when your body needs it.

Here’s a breakdown:

  1. Storage: Ferritin stores iron in a non-toxic form.
  2. Regulation: Ferritin regulates iron levels by releasing iron when needed.
  3. Indicator: Ferritin levels reflect iron stores.

Relationship between Ferritin and Iron Levels:

  • Low Ferritin: Indicates low iron stores (iron deficiency).
  • Normal Ferritin: Indicates sufficient iron stores.
  • High Ferritin may indicate:
    • Iron overload.
    • Inflammation.
    • Liver disease.

Iron Levels and Ferritin Ranges:

  1. Iron Levels:
    • Normal: 50-150 μg/dL.
    • Low: <50 μg/dL.
    • High: >150 μg/dL.
  2. Ferritin Levels:
    • Normal: 15-300 ng/mL.
    • Low: <15 ng/mL.
    • High: >300 ng/mL.

Ferritin ranges by age and gender:

  • Infants (0-12 months): 20-200 (ng/mL)
  • Children (1-18 years): 10-140 (ng/mL)
  • Adult Males: 20-300 (ng/mL)
  • Adult Females: 10-150 (ng/mL)
  • Pregnant Women: 6-130 (ng/mL)

Iron ranges by age and gender:

  • Infants (0-12 months): 40-100 (μg/dL)
  • Children (1-18 years): 50-120 (μg/dL)
  • Adult Males: 50-150 (μg/dL)
  • Adult Females: 40-120 (μg/dL)
  • Pregnant Women: 30-100 (μg/dL)

Interpretation of Results:

  1. Low Ferritin (<15 ng/mL) and Low Iron (<50 μg/dL): Iron Deficiency Anemia.
  2. High Ferritin (>300 ng/mL) and High Iron (>150 μg/dL): Iron Overload/Hemochromatosis.
  3. Elevated Ferritin (>300 ng/mL) with Normal Iron: Inflammation or Chronic Disease.

Clinical Significance:

  • Iron Deficiency Anemia: Low ferritin and iron levels.
  • Iron Overload: High ferritin and iron levels.
  • Chronic Diseases: Elevated ferritin (inflammation) with normal iron levels.

Factors Affecting Ferritin and Iron Levels:

  1. Diet (iron-rich foods).
  2. Inflammation (e.g., infections, autoimmune diseases).
  3. Chronic diseases (e.g., kidney disease, liver disease).
  4. Genetics (e.g., hemochromatosis).
  5. Menstrual cycle.

If your ferritin level is below the normal range, it means your ferritin levels (iron stores) are low. This may or may not indicate IDA (iron deficiency anemia).

To confirm a diagnosis of iron deficiency anemia, other factors like your red blood cell count and hemoglobin levels are also checked to find out.

Normal hemoglobin levels for males are between 13.0-17.0 g/dL, and for females is 11.3-16.0 g/dL. For a normal RBC count ranges in adult males is 4.32-5.72 million/μL, and adult females: 3.90-5.30 million/μL

If the hemoglobin levels and RBC count is below the normal range, this could be a sign of low ferritin and low iron, indicating iron deficiency anemia.

Causes of Low Ferritin Levels

The most common causes of low ferritin levels include:

  • Poor iron intake: This happens if you don’t eat iron-rich foods.
  • Blood loss: Due to kidney injury, bladder injury, childbirth, ulcers, or internal bleeding.
  • Malabsorption conditions: Celiac disease, Crohn’s disease, IBD and ulcerative colitis.
  • Pregnancy: Pregnant women need more iron than usual to support the growth of their baby.

Women in their heavy menstrual period are also likely to see a drop in their ferritin levels due to loss of blood.

Signs and Symptoms of Iron Deficiency Anemia

A low ferritin level is a sign that your iron stores are low. Common symptoms of IDA (iron deficiency anemia) include:

  • Fatigue
  • Pale skin
  • Shortness of breath
  • Dizziness
  • Headache
  • Cold hands and feet

Diagnostic Tests for Iron Deficiency Anemia

A ferritin blood test measures the level of ferritin that is in your blood. This test helps to diagnose iron deficiency anemia.

Other relevant tests may include:

  • Complete blood count (CBC)
  • Ferritin Test
  • Hemoglobin test
  • Serum iron test
  • Total iron-binding capacity (TIBC)
  • Transferrin saturation test

If you want to check your ferritin and iron levels, you can do these affordable tests at healthlabs.

Treatment and Prevention of Low Ferritin Levels & Iron deficiency Anemia

If you have poor dietary iron intake, your ferritin level may drop.

Iron deficiency anemia is usually treated with iron supplements. In some cases, intravenous iron therapy (iron infusion) may be necessary.

Once iron deficiency is corrected, your ferritin levels restores back to normal.

To help prevent the condition, make sure to eat iron-rich foods if you’re feeling mild symptoms of IDA. Here’s a list of Iron-rich foods to boost your ferritin levels:

  • Red meat
  • Beans
  • Tofu
  • Spinach
  • Kale
  • Raisins
  • Prunes
  • Iron-fortified cereals and breads

Iron supplements are also helpful, but taking too much of iron supplements can be harmful, you just have to be careful with the dosage.

List of the best iron supplements to boost your ferritin levels:

  • Lactoferrin 200mg: Supports iron level balance and the immune system. High dosage with 200 mg of lactoferrin per capsule, and its made from 100% fresh swiss alpine milk.
  • Iron Blood Builder: MegaFood Blood Builder is shown in an 8-week clinical study to increase iron levels in individuals with low iron, without causing nausea or constipation. Real foods like beets and oranges are added, with key nutrients like folate, iron and B12, that help to improve energy levels and combat fatigue. Vitamin C is included to support iron absorption.
  • Floravital Iron + Herbs: This liquid herbal supplement is a yeast-free, gluten-free, and vegan alternative to Floradix liquid iron supplement, which is the best-selling natural liquid iron supplement in the U.S. today. Containing nutritional iron in a gentle-to-digest and easily absorbed formula with vitamin C, essential B complex vitamins, and herbal extracts to help you live your best life.
  • Floradix Iron + Herbs, 120 Liquid Phyto-Caps: This Floradix Iron + Herbs extension is different from other iron offerings as it combines a clinically studied iron form, Ferrochel, in a liquid phyto-capsule along with herbs traditionally used to support healthy blood and blood flow.

In some severe cases where the ferritin levels are very low due to bladder injury, heavy menstrual period, or bleeding after child birth, special treatment is required.

Takeaway

Ferritin is a key indicator of iron stores, helping diagnose, manage, and treat iron deficiency anemia. Understanding ferritin ranges and interpreting results can help you to take control of your iron health.
