Iron is an essential mineral that keeps your body functioning smoothly. Yet, iron deficiency is one of the most common nutrient deficiencies worldwide, affecting energy levels, immune function, and overall well-being. Whether you're feeling fatigued or just want to optimize your health, understanding iron and how to maintain healthy levels is key.
What Is Iron Deficiency?
Iron deficiency occurs when your body doesn’t have enough iron to produce hemoglobin, the protein in red blood cells responsible for carrying oxygen throughout your body. Without adequate iron, your tissues and muscles receive less oxygen, which can lead to a variety of symptoms.
Why Iron Deficiency Happens
Iron deficiency can be caused by several factors, including:
Inadequate Intake: Not consuming enough iron-rich foods, especially in plant-based diets, can lead to deficiency. Vegans and vegetarians need to be particularly mindful of their iron sources.
Increased Needs: Conditions such as pregnancy, heavy menstruation, or rapid growth periods (like adolescence) heighten the body's demand for iron.
Malabsorption: Gut health issues, including conditions like celiac disease, irritable bowel syndrome (IBS), low stomach acid, or even the presence of parasites, can impair the body's ability to absorb iron effectively. The state of the gut microbiome also plays a significant role; an imbalance in gut bacteria can hinder nutrient uptake.
Blood Loss: Chronic blood loss, whether from menstruation, ulcers, or gastrointestinal issues, is a common cause of iron deficiency.
Age Factors: As individuals age, their ability to absorb nutrients, including iron, often decreases. Older adults may also experience a reduced appetite or dietary restrictions, which can contribute to inadequate iron intake. Additionally, certain medications common among older populations may interfere with iron absorption.
High Stress Levels: Elevated stress levels can impact digestion and gut health, potentially exacerbating malabsorption issues and further contributing to iron deficiency.
Signs and Symptoms of Iron Deficiency
Low iron levels can present with a variety of signs and symptoms, including:
Fatigue and weakness
Muscle fatigue and heaviness
Restless legs
Shortness of breath
Dizziness or headaches
Yawning
Cold hands, feet and body
Brittle nails and hair breakage/loss
Craving for ice or red meat
Poor concentration
Easy bruising
Pale skin, lower eyelids, gums, tongue and nail beds
Frequent infections or sick for longer
Learning and behavioural problems in children
If left untreated, iron deficiency can develop into iron deficiency anemia, a more severe form that affects daily function and long-term health.
What You Can Do About It
If you suspect you’re low on iron, the first step is to get your levels checked through a blood test, either with your doctor or nutritionist
Recommended Labs for Testing Iron Levels:
Full Blood Count (CBC): This test provides a comprehensive overview of your blood health, including hemoglobin levels and red blood cell counts.
Iron Studies: This includes ferritin levels, which are crucial since a decrease in ferritin is often one of the first signs of iron deficiency.
B Vitamins: It’s important to assess levels of B vitamins, particularly B9 (folate) and B12, as they play a vital role in red blood cell production.
Inflammatory Markers: Since inflammation can affect iron levels, these markers help us understand if your iron levels are accurately reflected in the tests.
Additional Tests: In some cases, it may also be beneficial to evaluate other nutrients like zinc and copper to get a more complete picture of your nutritional status.
From there, you can work on boosting your intake of iron through dietary changes or supplements if necessary.
1. Increase Iron-Rich Foods
To maintain healthy iron levels, it's essential to include a variety of iron-rich foods in your diet. Focus on both heme and non-heme sources. Heme iron, found in animal products Non-heme iron, which comes from plant-based
2. Pair Iron with Vitamin C
Vitamin C significantly boosts the absorption of iron. Try pairing iron-rich foods with vitamin C-rich ones, such as combining spinach with bell peppers or adding lemon juice to lentils.
3. Avoid Iron Blockers
Certain foods and drinks can inhibit iron absorption. Limit coffee, tea, chocolate and calcium-rich foods around your meals that contain iron. It's best to enjoy these outside of mealtime.
Iron-Rich Foods to Include in Your Diet
Iron comes in two forms: heme (from animal sources) and non-heme (from plant sources). Here’s a breakdown of each:
Heme Iron Sources (More Readily Absorbed)
Red Meat (beef, lamb)
Poultry (chicken, turkey)
Seafood (salmon, sardines, oysters, clams)
Organ Meats (liver, kidneys)
Non-Heme Iron Sources (Plant-Based)
Leafy Greens (spinach, kale, Swiss chard)
Legumes (lentils, chickpeas, beans)
Tofu and Tempeh
Fortified Cereals and Breads
Nuts and Seeds (pumpkin seeds, sunflower seeds)
Quinoa and Amaranth
Add citrus fruits, strawberries, tomatoes, or bell peppers to meals to maximize iron absorption.
Choosing the Right Iron Supplement for You
Choosing the right iron supplement can significantly impact how well you tolerate it and how effectively your body absorbs the iron. If you need to take iron supplements, it’s important to be aware that symptoms such as bloating, constipation, and black tarry stools can occur because the body may not be fully absorbing the iron. To optimize absorption and minimize these side effects, it's advisable to take the supplements every second day.
I can help you find the most suitable option tailored to your individual needs, ensuring you receive the benefits without the discomfort.
Iron deficiency is common but manageable through diet and lifestyle adjustments. By incorporating both heme and non-heme iron sources, pairing them with vitamin C, and staying mindful of inhibitors like coffee and tea, you can boost your iron levels naturally and prevent the fatigue and other symptoms associated with low iron.
