Iron Deficiency in Women of Reproductive Age: A Silent Epidemic Worth Screening and Treating

Speak to your Centrum Pharmacist about which iron supplement is right for you—and safe with your current medications.

Iron deficiency—whether or not it causes anemia—can profoundly affect your energy, sleep, mental health, and overall well-being. Yet, it’s often overlooked, especially in women of reproductive age.

At Centrum Pharmacy, we encourage proactive conversations about your iron status, particularly if you’re pregnant, planning to become pregnant, or experiencing heavy menstrual periods. Whether you’re already taking supplements or just feeling more tired than usual, your pharmacist is a vital ally in making sure your supplements are effective—and safe to take alongside your current medications.

What the Experts Are Saying

A recent review published in the Canadian Medical Association Journal (CMAJ) urges physicians to actively screen and treat iron deficiency in women of reproductive age, even if they aren’t anemic.

Why it matters:

• Non-anemic iron deficiency: occurs when iron stores are low but red blood cell counts remain normal. This can still impact your health, mood, and energy.
• Iron deficiency anemia: occurs when both iron and red blood cell levels drop, and carries more severe health risks—especially during pregnancy.

Symptoms of iron deficiency include:

• Brain fog
• Mood swings
• Sleep disturbances
• Hair loss
• Restless legs
• Poor exercise tolerance

Often, these symptoms are dismissed or normalized, leading to delayed diagnosis and treatment.

Better Screening = Better Health Outcomes

Thanks to work by Canadian hematologists and the Hemequity Lab at St. Michael’s Hospital in Toronto, ferritin lab cutoffs are being adjusted for earlier detection. In Ontario, major labs like LifeLabs, DynaCare, and Alpha now flag ferritin levels below 30 µg/L as iron deficient, and levels between 30–50 µg/L as at risk.

CMAJ Recommendations

• CBC and ferritin tests every 3 years in asymptomatic women of reproductive age, especially if they have heavy menstrual bleeding.
• Routine screening in pregnancy—early ferritin testing can prevent complications and support healthier outcomes for both mother and child.

Why This Matters in Pregnancy

Pregnancy increases iron demands dramatically—up to 1000 mg over the course of gestation. That’s equivalent to eating 177 steaks, which isn’t realistic.

Iron deficiency in pregnancy is associated with:

• Low birth weight
• Preterm birth
• Intellectual disabilities
• ADHD or autism

WHO recommends 30–60 mg of elemental iron daily during pregnancy.

Treatment Options & the Role of Your Pharmacist

If your ferritin is low but your hemoglobin is still normal, don’t wait for things to get worse.

First-line treatment includes:

• Ferrous gluconate
• Ferrous sulfate
• Ferrous fumarate

Tips:

• Take once daily
• Preferably on an empty stomach
• Consistency matters more than the type of iron—choose one you can tolerate

IV iron is an option if oral forms are not effective or tolerated.

At Centrum Pharmacy, our pharmacists can:

• Help interpret your ferritin and hemoglobin numbers
• Identify safe and effective supplements
• Monitor for side effects or interactions
• Liaise with your doctor if stronger options are needed
