Iron is one of the most commonly deficient minerals in Nigeria, particularly among women and children. What makes it especially tricky is that the signs develop slowly and quietly. By the time most people connect their symptoms to low iron, they have been deficient for months.
This blog explains every major sign of iron deficiency, why it happens, who is most at risk in Nigeria, and what to do about it.
What Does Iron Actually Do?
Iron is an essential mineral with one primary, irreplaceable job: it makes haemoglobin, the protein in red blood cells that carries oxygen from the lungs to every organ, muscle, and tissue in the body.
When iron is low, the body produces fewer and smaller red blood cells that carry less oxygen. Every cell in the body that depends on oxygen, which is every cell, begins to function at a lower level. The effects are felt everywhere.
Iron also supports immune cell function, energy metabolism, and cognitive performance. Low iron impairs all three simultaneously, which is why iron deficiency produces such a wide range of symptoms that are easy to attribute to other causes.
Who Is Most at Risk of Low Iron in Nigeria?
The following groups have the highest risk:
- Women of reproductive age due to monthly menstrual blood loss
- Pregnant women whose iron demands increase significantly to support the growing baby
- Children and adolescents whose growth increases iron requirements
- People who eat mainly plant-based or carbohydrate-heavy meals with little red meat or liver
- People whose diets are high in phytates, found in grains and legumes, that block iron absorption
- Frequent blood donors who lose iron regularly
- People who have recently had surgery, illness with significant blood loss, or certain gastrointestinal conditions
A 2024 report from JAMA Open Network found that 34 percent of women between the ages of 18 and 50 are iron deficient. Nigerian women face even higher rates given the documented prevalence of iron deficiency anaemia across the country.
The Signs You Need More Iron
1. Persistent, Unexplained Fatigue
This is the most common sign of iron deficiency and also the most frequently dismissed. Iron-related fatigue is not the ordinary tiredness that comes from a busy day. It is a heavy, pervasive exhaustion that does not improve with rest, that makes ordinary tasks feel unusually effortful, and that persists day after day regardless of how much sleep you get.
This happens because when haemoglobin is low, muscles and organs receive less oxygen. Producing energy without enough oxygen is difficult and the body compensates by slowing everything down.
If you have been tired for weeks or months without a clear cause, low iron should be among your first investigations.
2. Pale or Dull Skin, Lips, and Gums
Haemoglobin is what gives blood its red colour. When haemoglobin levels drop due to iron deficiency, blood carries less red pigment. This shows in the skin, particularly in areas where blood vessels are close to the surface.
Look at the inside of your lower eyelids. If the usually pink-red tissue appears pale or white, this is a strong visual sign of low haemoglobin. The lips and gums may also appear paler than usual. Skin may look dull, washed out, or grey rather than its normal tone.
A dermatologist case in New York reported that patients with low iron stores frequently present with pale, dry, and cracking skin that resolves with iron correction. This pattern is consistent with what Nigerian dermatologists observe in women with iron deficiency.
3. Shortness of Breath During Normal Activity
When the blood carries less oxygen, the body compensates by breathing faster and the heart beats harder. Activities that previously caused no effort, climbing stairs, walking quickly, carrying shopping, or speaking a long sentence, may start to cause noticeable breathlessness.
This symptom is especially worth taking seriously if you were previously comfortable with these activities and have noticed a gradual change over weeks or months.
4. Frequent Headaches and Dizziness
The brain is highly sensitive to oxygen supply. When iron deficiency reduces the oxygen the blood delivers to the brain, headaches become more frequent and light-headedness or dizziness can occur, especially when standing up quickly or after physical activity.
If you are experiencing more headaches than usual and have other symptoms from this list, iron is worth investigating.
5. Cold Hands and Feet
When oxygen delivery to the body's tissues is reduced, the body prioritises circulation to vital organs including the heart and brain. The extremities, hands and feet, receive less blood flow as a result. Cold hands and feet, even in warm weather, is a classic and consistent sign of iron deficiency anaemia.
6. Brittle Nails and Hair Loss
Iron deficiency affects the health of rapidly dividing cells including those in the nail bed and hair follicles. Nails may become brittle, break easily, or develop a distinctive concave shape known as koilonychia or spoon nails. Hair may become dry, thin, and fall out more than usual.
A 2024 clinical study in Cureus documented brittle nails and hair changes as consistent secondary signs of iron deficiency in hospitalised patients with anaemia.
7. Brain Fog and Poor Concentration
Low iron reduces oxygen delivery to the brain, which directly impairs cognitive function. People with iron deficiency often report difficulty concentrating, poor memory, slower thinking, and an inability to stay mentally focused for extended periods.
This symptom is particularly impactful for students, professionals, and anyone whose work requires sustained mental performance. It is frequently attributed to stress or poor sleep without the underlying iron deficiency being identified.
8. Heart Palpitations
In moderate to severe iron deficiency, the heart compensates for reduced oxygen delivery by beating faster and harder. You may notice your heartbeat feeling unusually rapid, strong, or irregular during ordinary activities or at rest.
This symptom warrants prompt medical evaluation, as persistent palpitations can strain the heart over time.
9. Cravings for Non-Food Items (Pica)
One of the less commonly known but well-documented signs of iron deficiency is pica, the compulsion to eat non-nutritional items such as ice, clay, chalk, or even soil. This unusual craving is particularly associated with iron deficiency and generally resolves when iron levels are corrected.
In Nigeria, the practice of eating clay, known as nzu or kaolin, is often socially normalised in certain communities and among pregnant women. It is worth noting that this behaviour is a recognised clinical sign of iron deficiency that requires nutritional attention.
10. Restless Legs at Night
Restless leg syndrome, an uncomfortable urge to move the legs at rest or during sleep, is associated with iron deficiency. Iron plays a role in dopamine pathways in the brain and low iron disrupts the normal dopamine signals that regulate leg movement during rest.
If you experience uncomfortable sensations in your legs at night that make sleep difficult, iron deficiency is a possible contributing factor.
What to Do If You Have These Signs
First Step: See a Doctor
The diagnosis of iron deficiency requires a blood test measuring haemoglobin, serum ferritin, and full blood count. You can have iron deficiency without full anaemia, and symptoms can be significant even before haemoglobin drops below the clinical threshold.
A blood test confirms the diagnosis. Your doctor can then advise whether dietary changes, oral iron supplementation, or further investigation is needed.
Dietary Changes
Increase your intake of iron-rich foods:
- Liver and kidney: among the richest dietary sources of iron
- Red meat: beef provides significant haem iron that is well absorbed
- Beans and moi moi: good plant-based iron sources
- Ugu and dark leafy greens: iron plus folate and Vitamin A
- Fortified foods
Always pair iron-rich foods with a Vitamin C source. Vitamin C dramatically improves absorption of plant-based iron. A glass of orange juice, fresh tomatoes in your soup, or a piece of pawpaw alongside your beans significantly increases how much iron your body actually absorbs.
Avoid drinking tea or coffee within an hour of iron-rich meals, as the tannins in both drinks significantly reduce iron absorption.
Supplementation
A daily multivitamin that includes iron provides consistent daily nutritional support. For women in particular, maintaining daily iron intake through a comprehensive women's multivitamin is the most practical long-term protection against the iron depletion that monthly menstrual loss creates.
Nutrify Products That Support Iron Levels
The Nutrify Multivitamin for Women includes iron alongside Vitamin C in the same formulation, which directly supports iron absorption. It addresses the most common cause of iron deficiency in Nigerian women, which is the daily iron shortfall from a diet that does not fully replace menstrual losses.
The Nutrify Multivitamin for Men also contains iron and B vitamins that support red blood cell production and energy metabolism.
The Nutrify Super Fizz provides daily Vitamin C which, when taken with iron-rich meals, significantly enhances iron absorption from food. It is a practical daily tool for improving iron uptake without changing the foods you eat.
The Nutrify Multivitamin for Women 50+ and Multivitamin for Men 50+ support mature adults whose nutrient absorption may be declining.

Frequently Asked Questions
How do I know for certain if I am iron deficient?
The only way to confirm iron deficiency is through a blood test measuring serum ferritin and haemoglobin. If you have multiple symptoms from this list, especially persistent fatigue, pale skin, and shortness of breath, discuss testing with your doctor. You can have depleted iron stores and significant symptoms before full anaemia develops.
Can I correct iron deficiency with food alone?
Mild iron deficiency can be improved through dietary changes, particularly increasing liver, beans, ugu, and meat intake while consistently pairing these with Vitamin C. Moderate to severe deficiency, or deficiency in pregnant women, typically requires iron supplementation under medical supervision for meaningful correction within a reasonable time frame.
Why do Nigerian women have such high rates of iron deficiency?
Monthly menstrual blood loss consistently depletes iron. The typical Nigerian diet is high in plant-based iron sources whose absorption is blocked by the phytates found in grains and legumes. Animal protein sources like liver and beef that provide better-absorbed haem iron have become more expensive and less accessible. These factors combine to make iron deficiency almost structurally inevitable for many Nigerian women without active dietary management or supplementation.
Does drinking tea affect iron absorption?
Yes significantly. The tannins in tea, including Nigerian teas and herbal infusions, bind to iron in the gut and reduce its absorption. Avoid drinking tea within an hour before or after iron-rich meals or iron-containing supplements for maximum absorption.
How long does it take to correct iron deficiency?
With appropriate dietary changes and supplementation, iron stores typically start rebuilding within 4 to 6 weeks. Full correction of depleted ferritin stores can take 3 to 6 months of consistent daily iron intake. Haemoglobin levels usually improve before ferritin stores are fully replenished.
Final Thoughts
Low iron is one of the most common, most impactful, and most correctable nutritional problems in Nigeria. Persistent tiredness, pale skin, brain fog, and shortness of breath are not just the signs of a busy life. They are often your body's way of telling you it needs more iron.
Check your levels. Improve your diet. Take a daily supplement that includes iron. And give your body the oxygen it needs to function at its best.
