From the Guidelines

To quickly raise low ferritin levels with a value of 14.3 ng/mL, indicating iron deficiency, intravenous iron supplementation is the most effective treatment, as it can increase hemoglobin levels by 1 g/dL within 2 weeks and ferritin levels within 4-8 weeks, according to the most recent guidelines 1. When considering treatment options, it's essential to evaluate the underlying cause of iron deficiency and the patient's ability to tolerate oral iron supplements.

  • If oral iron supplements are tolerated, ferrous sulfate 325 mg once or twice daily between meals with vitamin C can be effective in raising ferritin levels.
  • However, if oral iron supplements are not effective or tolerated, intravenous iron supplementation is recommended, as it can provide a faster and more significant increase in ferritin levels 1. Some key points to consider when using intravenous iron supplementation include:
  • The frequency of administration and duration of benefit depend on the underlying etiology of the iron deficiency.
  • Laboratory evaluation following IV iron should include a CBC and iron parameters (ferritin, percent transferrin saturation) 4 to 8 weeks after the last infusion.
  • The goal ferritin level is 50 ng/mL, regardless of sex at birth, and hemoglobin concentrations should increase within 1-2 weeks of treatment. It's crucial to monitor laboratory parameters and adjust treatment accordingly to ensure optimal iron replenishment and minimize the risk of adverse reactions.
  • Reticulocyte hemoglobin content (CHr) or reticulocyte hemoglobin equivalent (RET-He) can be used as quick and reliable tests for detecting iron deficiency and the need for iron replacement 1.
  • Soluble transferrin receptor (sTfR) can also be used to evaluate iron status, especially in patients with inflammatory conditions where ferritin levels may be unreliable 1.

From the FDA Drug Label

CONTAINS: Each tablet contains 324 mg of ferrous sulfate, equivalent to 65 mg of elemental iron, providing 362% of the U.S. recommended daily intake (RDI) of iron for adults and children 4 and older. To quickly raise low ferritin levels, ferrous sulfate can be used. The recommended dose is not specified in the label, but the label indicates that each tablet contains 65 mg of elemental iron.

  • Take one tablet of ferrous sulfate orally to provide 65 mg of elemental iron. It is essential to consult a healthcare professional to determine the appropriate dosage and treatment plan for iron deficiency, as the label does not provide direct guidance on this topic 2.

From the Research

Raising Low Ferritin Levels

To quickly raise low ferritin levels, several options are available:

  • Oral iron supplementation is the first line of treatment for iron deficiency anemia and pre-anemic iron deficiency, as stated in 3 and 4.
  • Ferrous sulfate is the simplest, least expensive, and most commonly prescribed oral iron supplement, but it can cause gastrointestinal side effects, as mentioned in 3 and 5.
  • Other oral iron formulations, such as ferric maltol, nanoparticle encapsulated sucrosomial iron, and iron protein succinylate, are also available and may have better tolerability profiles, as discussed in 3 and 5.
  • Intravenous iron therapy can rapidly achieve therapeutic targets without gastrointestinal complications when oral iron supplementation is contraindicated, as noted in 3.

Effective Dosage and Frequency

The effective dosage and frequency of oral iron supplementation are crucial:

  • Daily doses of 80-200 mg of elemental iron are commonly recommended, as stated in 5.
  • Lower therapeutic doses may be sufficient for managing iron deficiency anemia, as suggested in 5 and 6.
  • The frequency of administration can vary, with some studies evaluating the effects of daily or alternate-day supplementation, as mentioned in 6.

Combining Supplementation with Dietary Education

Combining oral iron supplementation with dietary education may be an effective approach:

  • A systematic nutrition intervention that combines supplementation with dietary education can help increase iron intake and potentially improve ferritin levels, as discussed in 7.
  • Increasing dietary intake of iron-rich foods and enhancing iron absorption through vitamin C consumption can support oral iron supplementation, as noted in 7.
