Project Summary: Iron Deficiency
Iron deficiency and anemia are commonly diagnosed and can result in significant negative health impacts if not treated. Intravenous iron offers a rapid treatment option that is often superior to oral iron.

- Iron deficiency anemia is the most common blood problem in the world.
- Iron deficiency can result in anemia, in which not enough red blood cells are available to carry oxygen throughout the body.
- Symptoms include feeling tired, weak or dizzy and having pale skin, cold hands and feet. Other symptoms include headache, swollen legs, restless leg syndrome, and dry or brittle hair and nails. Occasionally, it can cause chest pain, a fast heartbeat and shortness of breath.
- The first line of treatment for low iron levels and anemia is usually oral iron tablets.
- Oral iron supplements are often discontinued due to side effects, including gastrointestinal issues. This is especially problematic for individuals suffering from inflammatory bowel disease.
- In some cases, oral iron supplementation does not increase iron levels or reduce anemia.
- Medical guidelines for the treatment of iron deficiency anemia are outdated in many countries.
- The Parsemus Foundation provides evidence-based information on better treatment options for common ailments.
- Intravenous iron infusion offers a rapid recovery from iron deficiency and anemia, often with only one or two treatments.
- Intravenous iron is preferred over oral iron supplements to replace iron in iron deficient individuals with chronic inflammatory conditions or when oral therapy is poorly tolerated or ineffective.

Intravenous iron quickly cures anemia
For individuals suffering from iron deficiency anemia, the most common treatment is oral iron supplements. However, intravenous iron allows complete replacement of iron and alleviation of anemia in one (or more) sessions. With the development of safer solutions, IV iron has been used more often for anemic individuals with inflammatory bowel disease, gynecological and obstetric issues, renal failure, and cancer. Yet it is still an underutilized method due to outdated methods and safety concerns. IV iron may be particularly helpful for older individuals, who may not even realize that they have iron deficiency.
Iron deficiency anemia is the most common nutritional deficiency worldwide
Anemia indicates that you don’t have enough healthy red blood cells to carry adequate oxygen to your body’s tissues. Iron deficiency is the most common cause of anemia worldwide, affecting approximately 27% of the world’s population. It is more common in developing countries.
It is important to note that iron deficiency can also occur without anemia, and is at least twice as common as anemia. Iron deficiency without anemia refers to low iron stores that do not meet the body’s iron requirements. It has similar symptoms, diagnosis, and treatment options.
Iron deficiency causing anemia may be due to blood loss, menstruation and pregnancy in women and their children, malaria, hookworm, dietary conditions lacking adequate iron, celiac disease, cancer, kidney disease, and conditions causing an inability to absorb iron. About 10% of individuals over 65 years and more than 20% of individuals over 85 years are anemic. Anemia in the elderly is typically mild, but results in adverse outcomes like longer hospitalization, disability, and increased mortality risk and impacts on quality of life (fatigue, depression, frailty, etc.).
Iron levels may appear normal in individuals with inflammatory syndromes (chronic heart failure, chronic kidney disease, cancers, and bowel inflammatory diseases) even when there is a low iron store.
Symptoms of iron deficiency
Initially, iron deficiency anemia can be so mild that it goes unnoticed. But as the body becomes more deficient in iron and anemia worsens, the signs and symptoms intensify. Note that iron deficiency without anemia has many of the same symptoms:
- Extreme fatigue
- Weakness
- Pale skin
- Chest pain, fast heartbeat or shortness of breath
- Headache, dizziness or lightheadedness
- Cold hands and feet
- Restless legs syndrome
- Inflammation or soreness of your tongue
- Brittle nails
- Unusual cravings for non-nutritive substances, such as ice, dirt or starch
- Poor appetite, especially in infants and children with iron deficiency anemia
Diagnosing and treating iron deficiency with and without anemia
From our team:
The power of iron infusions
It can take years to get low iron stores taken seriously — in my case, eight years. In 2014, I went to a top university hospital with a ferritin count of 10, low by any standards. They basically ignored it. Eight years later, I got infusion treatment elsewhere and finally felt better. Why is it we have to do our own digging to find out there’s a difference between 'normal' and optimal? Just because something isn’t flagged on your lab report, that doesn’t mean it’s the end of the story. Even the professional societies have higher cutoffs now.
All those years of trying to raise my ferritin count with pills and thinking infusions are dangerous like they were decades ago…. Hopefully, you won’t have to learn the hard way like I did! If your ferritin is under 50 and you don’t feel right, and pills aren’t working, you deserve modern treatment."
Take Action on Iron Deficiency
If you have been diagnosed with iron deficiency with or without anemia, talk to your doctor about treatment options to see if intravenous iron is right for you. To diagnose an iron deficiency, evaluation of serum ferritin level, hemoglobin level, and percent transferrin saturation can be completed. If your doctor is not familiar with the modern use of intravenous iron to treat iron deficiency, the references under Additional Resources below may be useful. To find an iron infusion center, you can try this locator service from the National Infusion Center Association.
