7 Warning Signs Your Body Needs More Iron (And How to Boost It)
Iron plays a crucial role in maintaining our overall health. As a vital mineral, it helps form hemoglobin, the protein in red blood cells that transports oxygen throughout your body. Iron is also essential for muscle metabolism, supporting connective tissues, and maintaining your immune system. But when your body doesn’t have enough iron, it can lead to a range of symptoms that impact your daily life.
In this article, we explore the seven common signs that your body may need more iron and how you can boost your iron levels naturally.
1. Unexplained Fatigue and Weakness
One of the most common symptoms of iron deficiency is feeling constantly tired, even if you’re getting enough sleep. When iron levels drop, your body struggles to produce enough healthy red blood cells, leading to a decrease in oxygen circulation throughout your body. This causes you to feel fatigued and weak.
Moreover, iron deficiency is also linked to sleep disorders like insomnia and restless leg syndrome, which can worsen feelings of exhaustion. If fatigue persists and is accompanied by other symptoms like dizziness or pale skin, it could be a sign of iron deficiency anemia.
2. Feeling Cold More Than Usual
Do you find yourself feeling colder than those around you, even when the temperature seems normal? Iron deficiency can lead to poor circulation, reducing the amount of oxygen reaching your extremities, such as your hands and feet. This results in an overall feeling of being colder, even in normal conditions. If you experience this along with fatigue or pale skin, it’s worth considering whether iron deficiency could be the cause.
3. Pale Skin or Paleness in the Mouth
A decrease in red blood cells caused by iron deficiency can lead to paleness in the skin. This is especially noticeable in people with lighter skin tones, but even those with darker skin may notice paleness in the inner mouth or around the eyes. The reduced blood flow to your skin and organs means they aren’t getting the oxygen they need, leading to a pale or ashen appearance.
If you notice this symptom along with others, it might indicate a low iron level.
4. Frequent Dizziness or Lightheadedness
Dizziness and lightheadedness are common when iron levels are low. This is because your body doesn’t have enough red blood cells to carry oxygen to vital organs like your brain. When your brain receives insufficient oxygen, it can lead to feelings of dizziness, lightheadedness, or even fainting. If this is a regular occurrence for you, along with other symptoms, you might be dealing with iron deficiency.
5. Frequent Headaches
If you experience frequent headaches, it could be due to iron deficiency. When there isn’t enough iron in your blood, your body struggles to supply your brain with the oxygen it needs. This can cause blood vessels in the brain to swell, leading to headaches. A study has shown a strong link between chronic headaches and iron deficiency anemia. In some cases, people with iron deficiency may also experience migraines.
6. Brittle Hair and Nails
Iron deficiency can lead to weak, brittle nails that may even begin to take on a spoon-like appearance (koilonychia). This condition occurs when your nails curve inward and develop raised ridges. Hair thinning and hair loss are also common among people with iron deficiency. Iron is essential for nourishing hair follicles, and without it, hair growth slows down.
If your nails and hair have become weak or brittle, it might be time to check your iron levels.
7. Cravings for Non-Food Items (Pica)
One of the most unusual symptoms of iron deficiency is a condition known as pica, which is the craving for non-nutritive substances like ice, dirt, or paper. In the U.S., about 25% of people with iron deficiency experience a craving for ice (a condition known as pagophagia). This can be particularly common during pregnancy or in preadolescents. While the exact reason for pica is still unclear, it’s a well-known sign of low iron levels.
How to Test for Iron Deficiency
If you notice any of the above signs, it’s essential to get your iron levels checked. A healthcare provider can assess your iron status through blood tests, including:
- Complete Blood Count (CBC) – Measures your red blood cells and hemoglobin levels.
- Serum Iron and Ferritin Tests – Determines the amount of iron stored in your body.
- Total Iron Binding Capacity (TIBC) – Measures the blood’s ability to carry iron.
If you’re diagnosed with iron deficiency, your doctor will recommend the best course of action to restore your iron levels.
How to Boost Your Iron Levels
If you’re experiencing symptoms of iron deficiency, increasing your iron intake through food and supplements is the most effective way to improve your levels. Here are some ways to ensure you’re getting enough iron:
Iron-Rich Foods
To naturally boost your iron, incorporate more iron-rich foods into your diet. Good sources of iron include:
- Lean meats (beef, chicken, turkey)
- Fish and seafood (salmon, tuna, shellfish)
- Beans and lentils
- Tofu and tempeh
- Leafy greens (spinach, kale, collard greens)
- Iron-fortified cereals and grains
- Dried fruits (raisins, apricots, prunes)
Pair Iron with Vitamin C
Vitamin C helps your body absorb iron more efficiently, especially from plant-based sources. Pairing foods like spinach or beans with vitamin C-rich foods such as oranges, strawberries, or bell peppers can enhance iron absorption.
Iron Supplements
If dietary changes aren’t enough, your doctor may recommend iron supplements. However, it’s essential to take them under medical supervision, as high doses of iron can cause side effects like nausea, constipation, or diarrhea. It can take 3-6 months of supplementation to restore healthy iron levels.
Special Considerations
In cases of severe iron deficiency, such as those caused by internal bleeding or conditions like celiac disease, intravenous iron therapy or blood transfusions may be necessary.
A Quick Review
Iron deficiency can have a significant impact on your health, leading to fatigue, dizziness, headaches, brittle hair, and more. If you notice these symptoms, it’s essential to get tested and seek guidance from a healthcare provider.
Eating iron-rich foods and pairing them with vitamin C can help boost your levels naturally. For those with severe deficiencies, supplements or medical treatments may be necessary to restore iron levels and prevent complications.
