Ferritin: 9 ng/mL

What does a ferritin level of 9 mean? Are there any symptoms associated with this level?

A ferritin level of 9 ng/mL is considered low. Ferritin is a protein in your blood that stores iron; therefore, low ferritin levels may indicate iron deficiency and can lead to iron-deficiency anemia. Iron-deficiency anemia is a condition where you have too few red blood cells, which can hinder sports performance, cognition, immunity, and more.
Symptoms associated with low ferritin include shortness of breath, irritability, fatigue, dizziness, increased hair shedding, and heart palpitations. If you have iron deficiency anemia related to low ferritin, you may also experience chest pain, fast heartbeat, pale skin, cold hands and feet, brittle nails, or a sore or inflamed tongue.

Factors that could contribute to a ferritin level of 9

Numerous factors impact ferritin levels, including [1]: 
  • Diet: Diets low in iron put you at greater risk of having low ferritin levels. People who don't eat meat may have a greater risk of iron deficiency anemia if they don't get enough dietary iron from other sources.
  • Heavy athletic training: Intense physical training may increase your body’s iron needs, which might lead to a drop in ferritin.
  • Heavy menstruation: Heavy menstrual bleeding increases your body’s iron needs and can lower ferritin levels.
  • Pregnancy: Pregnancy increases iron needs which can reduce ferritin levels. 
  • Intestinal surgeries: Intestinal surgeries can reduce your body’s ability to absorb iron from digested food, leading to low ferritin levels and possibly iron-deficiency anemia.
  • GI conditions and diseases: Certain GI diseases and conditions can also decrease iron absorption and cause lower ferritin levels, including ulcerative colitis, celiac disease, Crohn’s disease, colon cancer, and peptic ulcers.  

What to do if your ferritin level is 9?

You can naturally boost ferritin levels by increasing your intake of iron from foods. Here are some ways you can get more iron from your diet.
  • Eat more lean meat. Research has shown that eating lean meat once per day can increase ferritin levels, so if you choose to eat meat, it’s encouraged to eat a variety of red and lean meats [2]. 
  • Pair iron with vitamin C. Vitamin C increases the absorption of non-heme (plant-based) iron. Squeeze lemon over dark leafy greens to increase the iron amount you absorb.
  • Soak, sprout, and ferment grains and legumes. Soaking, sprouting, and fermenting grains and legumes improve iron availability by lowering the phytates naturally present in these foods that can bind to iron and prevent its absorption [3]. 
  • Cook in a cast-iron pan. Research shows that using cast-iron cookware may increase the iron content in your food by up to 16% [4]. 
  • Consume copper-rich foods. Copper is essential for absorbing iron in the intestines [5]. You can increase your ferritin levels by consuming more copper-rich foods, like shellfish, liver, fatty fish, oysters, spirulina, shiitake mushrooms, lobster, and dark chocolate.

Medications and supplements used to improve ferritin levels


If you have severe anemia in addition to low ferritin, your doctor may recommend intravenous iron to quickly increase your iron levels and help replenish iron stores. 


If you have low ferritin, oral iron supplements can help improve your levels by increasing your iron stores. Because iron dosages, tolerance, and effectiveness can vary from person to person, and too much iron can lead to iron toxicity, iron supplements should be taken under a doctor or dietitian’s supervision.
The most common iron supplements include [6]: 
  • Ferrous sulfate
  • Ferrous gluconate
  • Ferric citrate
  • Ferric sulfate
Generally speaking, ferrous iron supplements tend to be better tolerated and more cost-effective than ferric iron [7]. Speak with a healthcare professional to decide which form of iron will best fit your needs and minimize any side effects.
