Iron Supplements Aren’t Always Enough: When Is an Iron Infusion the Better Choice?

Iron deficiency is one of the most common findings we see in practice.

Many patients are told their iron is low and are advised to start an iron supplement. In some cases, that’s exactly the right approach.

However, there are also many patients who continue to struggle with fatigue, hair loss, poor exercise recovery, brain fog, shortness of breath, and low energy despite taking iron for months.

The reason is simple.

Taking iron and absorbing iron are two very different things.

The Limitations of Oral Iron

Iron supplements can be effective, but they are not always the best solution.

Absorption Can Be Poor

The body tightly regulates how much iron it absorbs from the digestive tract.

Even when iron stores are low, only a portion of the iron you swallow may actually be absorbed and utilized.

Several factors can further reduce absorption, including:

• Proton pump inhibitor medications such as Pantoloc, Nexium, or Dexilant

• Celiac disease

• Inflammatory bowel disease

• Previous gastric bypass surgery

• Chronic inflammation

• Calcium supplementation

• Coffee or tea consumed close to the time iron is taken

Side Effects Are Common

Many patients struggle with:

• Constipation

• Nausea

• Stomach discomfort

• Bloating

• Digestive upset

These side effects often make it difficult to stay consistent with treatment.

Progress Can Be Slow

Iron deficiency often develops gradually over months or years.

Unfortunately, restoring iron stores through supplementation can also take months. For patients with significant symptoms, waiting six months or longer to feel better can be frustrating.

When IV Iron May Be Worth Considering

Intravenous iron bypasses the digestive system entirely and delivers iron directly into the bloodstream.

This allows us to replenish iron stores more efficiently without relying on intestinal absorption.

IV iron may be considered for patients who:

• Cannot tolerate oral iron

• Have failed to respond adequately to supplementation

• Have a significant iron deficiency

• Have ongoing blood loss

• Have digestive conditions that impair absorption

• Need a faster restoration of iron stores

For the right patient, IV iron can be a game changer.

Why We Use Monoferic

At Cornerstone Naturopathic, we use Monoferic (ferric derisomaltose), one of the newer intravenous iron therapies available in Canada.

One of the biggest advantages of Monoferic is that a large amount of iron can often be administered in a single visit.

This means:

• Fewer appointments

• Faster correction of deficiency

• Greater convenience

• Improved patient experience

Studies have demonstrated that ferric derisomaltose effectively increases both ferritin and hemoglobin levels in patients with iron deficiency and iron deficiency anemia.

Modern IV iron products have also demonstrated significantly improved safety profiles compared to older formulations.

As with any medical treatment, proper screening and monitoring are essential, but Monoferic is generally very well tolerated when administered in an appropriate clinical setting.

How Quickly Will I Feel Better?

This is one of the most common questions we receive.

The answer depends on the individual.

Some patients notice improvements in energy, exercise tolerance, mental clarity, and recovery within a few weeks.

Others experience a more gradual improvement over one to three months as iron stores are replenished and the body restores normal function.

Our goal is not simply to improve a laboratory value.

Our goal is to help patients feel and function better.

How Is The Dose Determined?

One of the most common misconceptions about IV iron is that everyone receives the same amount.

That is not the case.

The amount of iron required depends on several factors, including:

• Ferritin levels

• Hemoglobin levels

• Severity of symptoms

• Body weight

• Underlying medical conditions

• Previous response to iron supplementation

Before recommending IV iron, we carefully review your blood work and overall clinical picture.

In most cases, recent laboratory testing is required before treatment can be considered. This often includes ferritin, a complete blood count (CBC), and other iron markers as indicated.

Not everyone with a low ferritin requires IV iron.

Likewise, not everyone experiencing fatigue is iron deficient.

The goal is to identify the underlying issue, determine whether iron deficiency is contributing to symptoms, and recommend the most appropriate treatment.

Is IV Iron Right For You?

For many people, dietary changes and oral iron supplementation remain appropriate first-line treatments.

However, if you have ongoing symptoms, poor tolerance to iron supplements, difficulty raising your ferritin levels, or significant iron deficiency, IV iron may be worth considering.

At Cornerstone Naturopathic, every patient begins with a comprehensive assessment and review of their laboratory results before treatment recommendations are made.

Because when iron deficiency is truly the problem, correcting it properly can have a profound impact on energy, cognitive function, exercise performance, recovery, and overall quality of life.

If you’re wondering whether low iron stores may be contributing to your symptoms, book an IV Iron Consultation with one of our Naturopathic Doctors to review your blood work and determine whether IV iron therapy may be appropriate for you.
