Iron Deficiency
Tired? Your iron may be part of the story.
Iron deficiency can affect how you feel long before it becomes obvious on a standard blood count. Fatigue, reduced stamina, headaches, dizziness, difficulty concentrating, feeling cold, restless legs or changes in your hair and nails can sometimes occur when iron stores are low — even when hemoglobin has not yet fallen into the anemic range.
At Sage Natural Health, we look beyond a single lab value. We assess your symptoms, health history, diet, menstrual or bleeding history, medications, previous blood work and other relevant factors to understand whether iron deficiency is present and what may be contributing to it.
Treatment may include nutrition support, oral iron, medical management, IV iron when appropriate, monitoring, or referral for further investigation.
Iron Deficiency, Low Ferritin & Iron-Deficiency Anemia
Iron deficiency occurs when the body’s iron stores are too low to meet its needs. If deficiency becomes more significant, it can lead to iron-deficiency anemia, where there is not enough hemoglobin to adequately carry oxygen through the body.
Some people have clear symptoms. Others have few or no symptoms.
Fatigue and low energy
You may feel unusually tired, have less stamina or find everyday activities more difficult than they used to be.
Brain fog and difficulty concentrating
Iron deficiency can be associated with difficulty concentrating, headaches and reduced mental energy.
Dizziness or lightheadedness
Feeling dizzy or lightheaded — particularly alongside fatigue or shortness of breath — can occur with iron deficiency or anemia.
Shortness of breath or reduced exercise tolerance
You may notice that physical activity feels harder than it used to, particularly when anemia is present.
Restless legs
Low iron stores can be associated with restless legs syndrome, and iron status may be considered as part of its assessment.
Hair, nail or skin changes
Hair thinning, brittle or spoon-shaped nails, pale skin and other changes can occur with iron deficiency.
Ice or non-food cravings
A craving to chew ice or other non-food substances, known as pica, can be associated with iron deficiency.
Heavy menstrual bleeding
Menstrual blood loss is a common contributor to iron deficiency. If your periods are heavy or prolonged, addressing the bleeding may be just as important as replacing the iron.
Iron-deficiency anemia
When iron deficiency affects red blood cell production enough to lower hemoglobin, it is considered iron-deficiency anemia and may require a more comprehensive investigation into the cause.
These symptoms are not specific to iron deficiency. Fatigue, dizziness, hair changes and brain fog can have many possible causes, which is why appropriate assessment matters.
Why Is Your Iron Low?
Your symptoms are the starting point — not the whole story.
There is no single reason people develop iron deficiency.
For some people, the main issue is blood loss, such as heavy menstrual bleeding. For others, iron intake may not meet their needs, particularly during periods of increased demand.
Iron deficiency can also occur when the body has difficulty absorbing iron. Conditions affecting the gastrointestinal tract, including celiac disease and inflammatory bowel disease, can contribute. Previous gastrointestinal surgery may also affect absorption.
The right evaluation depends on your age, symptoms, medical history and risk factors.
Importantly, replacing iron does not always address why the deficiency developed in the first place. If there is ongoing blood loss or another medical cause, that issue may also need to be investigated and treated.
Other possible contributors include:

Our Approach to Iron Deficiency
Individualized care — not an automatic iron protocol.
At Sage, we don’t believe every person with fatigue needs an iron supplement, and we don’t believe every person with low ferritin needs an IV.
Your care begins with understanding the bigger clinical picture.
Depending on your situation, your practitioner may consider:
- Your current symptoms and how they are affecting daily life
- Previous blood work and medical investigations
- Menstrual, pregnancy and postpartum history where relevant
- Dietary intake and nutritional factors
- Gastrointestinal symptoms and digestive health
- Medications and supplements
- Previous experience with oral iron
- Other medical conditions
- Possible sources of blood loss
- Whether further investigation or referral is appropriate
From there, your practitioner can determine whether you need additional testing, nutritional support, oral iron, IV iron, treatment for an underlying contributor, or referral to another healthcare professional.
There is no single “Sage protocol” for iron deficiency.
Comprehensive Care, Without Unnecessary Testing
Testing should answer a clinical question.
You may have seen long lists of specialty tests recommended for fatigue or low iron. At Sage, we don’t believe more testing automatically means better care.
For suspected iron deficiency, blood work is usually the starting point.
Depending on your circumstances, this may include:
Ferritin
Ferritin provides an estimate of your body’s stored iron and is an important test when evaluating iron deficiency.
The interpretation of ferritin is not always straightforward. Ferritin can be affected by inflammation and other health conditions, so a result should be interpreted in context rather than in isolation.
Complete blood count (CBC)
A CBC helps determine whether anemia is present and provides information about your red blood cells and hemoglobin.
Additional blood work
Depending on your history and initial results, your practitioner may consider additional tests to clarify the diagnosis or investigate another medical condition.
Investigating the cause
If iron deficiency or iron-deficiency anemia is confirmed, the next question may be why.
Depending on your age, sex, menstrual history, symptoms and risk factors, further investigation may involve your family physician, gynecologist, gastroenterologist or another specialist.
For example, unexplained gastrointestinal blood loss may require gastrointestinal investigation, while heavy menstrual bleeding may warrant gynecological assessment.
Diagnostic imaging is not routinely required simply to diagnose iron deficiency, but imaging or other specialist investigations may be appropriate when your clinical history suggests another source of bleeding or an underlying condition.
If additional medical investigation is needed, Sage can work alongside your existing healthcare providers or help coordinate an appropriate referral.
One Team. Multiple Healthcare Perspectives.
Iron deficiency is a good example of why healthcare doesn’t need to be divided into “natural” versus “conventional.”
Different patients need different tools.
Naturopathic medicine
A naturopathic doctor can assess your symptoms, health history, nutrition, previous investigations and contributing factors, while helping coordinate care when additional medical assessment is needed.
Nurse practitioner care
Sage’s nurse practitioners can assess and interpret laboratory results, prescribe medications and manage medical aspects of care within their scope. Sage’s NP team is also involved in the assessment and prescribing pathway for IV iron.
Dietitian support
Nutrition can be an important part of iron-deficiency care. A registered dietitian can help assess dietary iron intake and develop practical strategies that fit your preferences, nutritional needs and lifestyle.
Medical collaboration and referral
Sometimes the most appropriate next step is care outside Sage. If your history suggests significant blood loss, gastrointestinal disease, gynecological concerns or another medical issue requiring investigation, we can recommend collaboration with your family physician or referral to an appropriate specialist.
The goal isn’t to choose between conventional and naturopathic medicine. It’s to use the right tools for the right patient at the right time.

What Might Treatment Look Like?
Treatment depends on how low your iron is, whether anemia is present, why your iron is low, and how you respond to treatment.
Oral iron
For many people, oral iron is an appropriate first treatment. The type, dose and schedule can be individualized based on your situation and tolerance.
Some people experience constipation, nausea, abdominal discomfort or other gastrointestinal side effects. If oral iron is difficult to tolerate, that doesn’t mean you have run out of options.
Nutrition
Food can contribute to maintaining adequate iron intake, particularly when dietary intake is part of the reason iron stores are low.
A dietitian can help you build practical meals around iron-containing foods without unnecessarily restricting your diet or relying on a long list of supplements.
Addressing ongoing blood loss
If heavy menstrual bleeding or another source of blood loss is contributing to deficiency, replacing iron alone may not be enough. Your care may include appropriate medical treatment or referral to address the source.
IV iron
For selected patients, intravenous iron can be an appropriate treatment option.
IV iron may be considered when oral iron is not tolerated, has not produced an adequate response, iron absorption is impaired, ongoing blood loss makes oral replacement insufficient, or more rapid repletion is clinically appropriate.
At Sage, IV iron is medically assessed and prescribed through the clinic’s nurse practitioner pathway. Patients complete appropriate blood work before treatment, and the infusion is administered with clinical monitoring. Follow-up testing can then be used to assess the response and determine next steps.
Treatment can change over time
Your initial treatment is not necessarily your long-term treatment.
We reassess your symptoms, laboratory results and underlying circumstances and adjust the plan as needed.

Follow-up symptoms and laboratory results help determine whether treatment is working and what should happen next.
Frequently Asked Questions
Yes. Iron deficiency can occur before anemia develops. Ferritin is an important measure of iron stores, although results need to be interpreted in the context of inflammation and other health conditions.
If you suspect you have iron deficiency, it’s important to establish whether iron deficiency is actually present and consider why it may have developed before beginning treatment. Taking iron unnecessarily can cause problems and may delay investigation of another cause of anemia or fatigue.
Not necessarily. Many people can be treated with oral iron. IV iron is generally considered when oral iron is not tolerated, doesn’t provide an adequate response, absorption is impaired, there is ongoing blood loss, or faster repletion is clinically appropriate.
Yes. Your practitioner can review your previous experience with iron and consider whether a different oral approach, nutritional support, further investigation or IV iron may be appropriate.
Heavy menstrual bleeding is a common contributor to iron deficiency. Replacing iron can be part of the treatment, but it is also important to consider whether the bleeding itself requires assessment or treatment. Depending on your situation, this may involve collaboration with your family physician or gynecologist.
A recurring deficiency deserves another look. Your practitioner may review adherence and response to treatment, ongoing menstrual or other blood loss, dietary intake, absorption issues and whether additional medical investigation is warranted.
Sage can assess your history, symptoms and laboratory results and determine whether additional investigation is appropriate. If your situation requires testing, imaging or specialist assessment outside the clinic, we can recommend collaboration or referral rather than ordering tests simply because they are available.
Sage offers medically supervised IV iron at its Kitchener, Cambridge, Oakville and Etobicoke locations. The current pathway includes an initial prescreen, appropriate blood work and assessment by a nurse practitioner before an infusion is recommended.
Sage currently states that IV iron treatment is not covered by OHIP. Coverage through private or extended health benefits varies by plan, and the iron prescription, practitioner visits and infusion may be treated differently by your insurer. Check your specific benefits before treatment.
Current Sage pricing lists an IV iron nurse practitioner consultation at $150 and the IV iron infusion at $600, with the cost of the prescribed iron varying by dosage. Prices can change, so patients should confirm current fees before booking.
You Don’t Have to Keep Pushing Through the Fatigue
If you’re experiencing persistent fatigue, low stamina, dizziness, restless legs, heavy periods or other symptoms that make you wonder whether low iron could be involved, the first step is finding out what’s actually going on.
At Sage, we’ll help you understand your results, consider what may be contributing to the deficiency and determine which treatment options make sense for you.
Sometimes that means oral iron. Sometimes it means nutrition support. Sometimes it means IV iron. And sometimes the most important next step is investigating an underlying cause or involving another healthcare professional.
