Does beetroot consumption improve iron-deficiency anemia?

Beetroot Does NOT Improve Iron-Deficiency Anemia and Should NOT Be Used as Treatment

Beetroot consumption is not an evidence-based treatment for iron-deficiency anemia and should not replace standard iron supplementation therapy. The current high-quality clinical guidelines from the American Gastroenterological Association make no mention of beetroot or any herbal alternatives for treating iron-deficiency anemia, instead providing clear recommendations for oral iron supplementation (ferrous sulfate, ferrous fumarate, or ferrous gluconate) or intravenous iron therapy 1.

Why Beetroot Is Not Recommended

The evidence base for beetroot consists entirely of animal studies (rats) and one small human observational study—none of which meet the standards for clinical practice guidelines. While these preliminary studies suggest beetroot may have antioxidant properties and contain some iron 2, 3, 4, this does not translate to effective treatment of iron-deficiency anemia in humans.

Critical Problems with Beetroot as Treatment:

• No human clinical trials demonstrating efficacy in treating iron-deficiency anemia
• Unknown bioavailability of iron from beetroot in humans
• Unpredictable dosing—no standardized formulations or evidence-based dosing regimens exist
• Potential harm: Extreme consumption can cause metal ion accumulation in the liver, which could be particularly dangerous in patients with metal accumulation disorders 5
• Delays definitive treatment, potentially worsening anemia and its complications

What Actually Works: Evidence-Based Treatment

First-Line: Oral Iron Supplementation

Start with ferrous sulfate as it is the least expensive and equally effective as other formulations 1. The 2024 AGA guidelines provide clear direction:

• Dosing: Once daily at most—taking iron more frequently increases side effects without improving absorption due to hepcidin elevation 1
• Timing: Take on an empty stomach when possible for better absorption 1
• Enhance absorption: Add 500 mg vitamin C (ascorbic acid) to improve iron uptake 1
• Avoid inhibitors: Do not consume tea or coffee within one hour of taking iron 1

Expected response: Hemoglobin should increase by 1 g/dL within 2 weeks, and ferritin should rise within one month 1.

When to Use Intravenous Iron

Switch to IV iron if 1:

• Patient cannot tolerate oral iron (common side effects: constipation 12%, diarrhea 8%, nausea 11%)
• Ferritin levels fail to improve after one month of adherent oral therapy
• Conditions impairing absorption exist (inflammatory bowel disease, celiac disease, post-bariatric surgery)
• Ongoing blood loss exceeds oral iron absorption capacity

Preferred formulations: Those requiring only 1-2 infusions rather than multiple doses 1.

Address the Underlying Cause

Simply replacing iron is insufficient—you must identify and treat the source of iron deficiency 6, 1:

• Men and postmenopausal women: Bidirectional endoscopy to evaluate for GI blood loss (strong recommendation) 6
• Premenopausal women: Consider bidirectional endoscopy even if menstruation seems explanatory 6
• Test for H. pylori: Treatment improves hemoglobin by 2.2 g/dL more than iron alone (95% CI: 1.3-3 g/dL) 6
• Evaluate dietary intake: Nutritional consultation may be helpful 1

Common Pitfalls to Avoid

1. Do not use unproven herbal remedies like beetroot when evidence-based treatments exist
2. Do not take iron more than once daily—this only increases side effects without benefit 1
3. Do not assume menstruation fully explains IDA in premenopausal women without further evaluation 6
4. Do not continue oral iron indefinitely if ferritin fails to rise—switch to IV iron 1
5. Do not mistake infusion reactions for true allergy—most IV iron reactions are complement activation-related pseudo-allergy, not anaphylaxis 1

The Bottom Line

While beetroot contains folate and some iron, there is zero clinical evidence supporting its use for treating iron-deficiency anemia in humans. The standard of care remains oral iron supplementation (preferably ferrous sulfate with vitamin C) or intravenous iron when indicated, combined with investigation and treatment of the underlying cause 1. Using unproven alternatives delays effective treatment and risks progression of anemia with its associated morbidity including fatigue, reduced quality of life, and cardiovascular complications 1.
