Ferric Maltol vs Traditional Iron Supplements: What Should People With IBD Know?

Living with Inflammatory Bowel Disease (IBD), including Crohn’s disease and ulcerative colitis, can increase the risk of iron deficiency and anemia. Inflammation, intestinal blood loss, and reduced iron absorption can lead to fatigue, weakness, and reduced quality of life.

But choosing the right iron supplement isn’t always easy. Traditional oral iron can help restore iron levels, yet gastrointestinal side effects may add to existing digestive discomfort.

Could ferric maltol offer an alternative for people with IBD?

Let’s explore the key differences.

1. Understanding Iron Deficiency and Anemia in IBD

Iron is essential for producing hemoglobin, the protein in red blood cells responsible for carrying oxygen throughout the body. When the body does not have enough iron, hemoglobin production may decrease, potentially leading to iron-deficiency anemia.

People with IBD may develop iron deficiency for several reasons

• Chronic intestinal blood loss: Inflammation and ulceration in the digestive tract can cause ongoing blood loss.
• Reduced iron absorption: Intestinal inflammation and changes in digestive function may interfere with normal nutrient absorption.
• Reduced dietary intake: Abdominal discomfort, nausea, food avoidance, or dietary restrictions may reduce iron intake.
• Chronic inflammation: Inflammation can interfere with the body's ability to use and regulate iron effectively.
• Other nutritional deficiencies: Vitamin B12 and folate deficiencies may contribute to anemia, particularly in people with certain forms of IBD.

Symptoms may include fatigue, weakness, dizziness, headaches, breathlessness, and difficulty concentrating. Blood tests such as CBC, hemoglobin, ferritin, transferrin saturation, and CRP help assess iron deficiency.

Since inflammation can raise ferritin levels, results must be interpreted carefully to identify the cause of anemia and appropriate treatment.

2. Traditional Iron Supplements: How Do They Work?

Traditional oral iron supplements are widely used to replenish iron stores and support hemoglobin production.

Common formulations include ferrous sulfate, ferrous fumarate, and ferrous gluconate. These contain iron in the ferrous form, which the body can absorb through the gastrointestinal tract.

When prescribed for iron deficiency, these supplements can be effective and accessible options. Their suitability depends on the severity of the deficiency, the person's digestive health, and their ability to tolerate treatment.

Potential challenges for people with IBD

Although conventional oral iron can be beneficial, some people experience side effects such as:

• Nausea or vomiting
• Abdominal discomfort
• Constipation
• Diarrhea
• Bloating
• Dark-colored stools

These effects can be particularly difficult for people already experiencing abdominal pain, altered bowel habits, or other gastrointestinal symptoms.

The dose of elemental iron can influence tolerability. Some patients may benefit from a lower dose or alternate day dosing under medical supervision.

Importantly, traditional iron supplements are not unsuitable for every person with IBD. They may be appropriate for individuals with mild anemia and inactive disease who tolerate oral treatment.

The key is to select an approach that balances effectiveness, tolerability, and the person's current disease activity.

3. What Is Ferric Maltol?

Ferric maltol is an oral iron formulation in which ferric iron (Fe³⁺) is combined with maltol, an organic compound that helps form a stable complex.

It offers a different formulation from conventional ferrous iron salts and has been investigated as a treatment option for iron-deficiency anemia, including in adults with Crohn’s disease and ulcerative colitis.

Clinical research has shown that ferric maltol can improve hemoglobin levels in selected patients with IBD-associated iron-deficiency anemia, including some who previously had difficulty with conventional oral iron. (Cummings et al., 2021)

However, ferric maltol is not free from gastrointestinal side effects, and individual responses can vary.

4. Ferric Maltol vs Traditional Iron Supplements: Key Differences

Both ferric maltol and traditional oral iron supplements aim to address iron deficiency. Their formulations and individual tolerability profiles, however, differ.

Formulation

Traditional supplements commonly contain ferrous salts, such as ferrous sulfate or ferrous fumarate.

Ferric maltol contains ferric iron complexed with maltol. This formulation has been specifically studied in certain patient groups with iron-deficiency anemia, including people with IBD.

Gastrointestinal tolerability

Traditional iron and ferric maltol can both cause gastrointestinal side effects, including nausea, abdominal discomfort, constipation, and diarrhea. Ferric maltol may be an alternative for some patients who struggle with conventional iron.

Effectiveness

Both can help correct iron deficiency when appropriately prescribed. Treatment response varies.

Suitability for Different Stages of IBD

Oral iron may suit some patients with mild or inactive IBD. During active flares, ferric maltol may not be appropriate. Consult a healthcare professional before starting or continuing treatment.

When Is Intravenous Iron Considered?

Intravenous (IV) iron may be preferred for active IBD, severe anemia, poor absorption, oral iron intolerance, or an inadequate response to oral treatment. The choice depends on individual clinical needs.

5. Which Iron Supplement May Be Suitable for People With IBD?

The right iron supplement depends on disease activity, anemia severity, blood test results, ongoing bleeding, and previous tolerance to oral iron.

• Traditional oral iron: May suit patients with mild anemia and inactive IBD.
• Ferric maltol: May be considered for selected patients who struggle to tolerate conventional iron.
• Intravenous (IV) iron: May be preferred for active inflammation, severe anemia, poor absorption, or inadequate response to oral treatment.

Always consult a healthcare professional to determine the appropriate treatment. Iron supplementation does not replace treatment for the underlying intestinal inflammation.

6. Feritero Capsules: An IBD-Focused Approach to Iron Support

Managing iron deficiency in people with IBD requires attention to both iron status and individual nutritional needs.

Feritero Capsules – Tailor-Made Iron Support for IBD Patients combine ferric maltol with selected vitamins that contribute to important physiological functions.

The formulation includes

• Ferric maltol
• Folic acid
• Vitamin B12
• Vitamin C
• Vitamin D2

People with IBD may experience more than one nutritional deficiency. A formulation containing iron and selected vitamins brings together nutrients involved in iron replacement, red blood cell formation, and other essential physiological functions.

Feritero may be discussed with a healthcare professional as a potential option when iron supplementation and these additional nutrients are appropriate for the individual's needs.

Its suitability depends on the patient's laboratory findings, disease activity, medical history.

7. What Should People With IBD Check Before Starting Iron Supplements?

Before starting an iron supplement, it is important to confirm the presence of iron deficiency and understand what is causing it.

Conclusion: Choosing the Right Iron Support for IBD

Iron deficiency is common in people living with Crohn’s disease and ulcerative colitis. Addressing it can help manage anemia and support everyday well-being. While traditional oral iron supplements remain useful, ferric maltol offers an alternative for selected patients who have difficulty tolerating conventional formulations.

Feritero Capsules combine ferric maltol with folic acid and vitamins B12, C, and D2 in one formulation. The right approach depends on individual iron levels, IBD activity, and treatment needs. Patients should consult their healthcare professional to determine the most appropriate iron supplementation option.
