You're eating reasonably well, getting some sleep, managing your stress as best you can — and yet the tiredness just won't lift. If this sounds familiar, it's worth taking a closer look at one of the most common, and most commonly missed, culprits behind persistent fatigue: iron deficiency.
Why Iron Matters So Much
Iron plays a starring role in two processes that are absolutely central to feeling energised. First, it's a key component of haemoglobin, the protein in your red blood cells responsible for carrying oxygen from your lungs to every tissue in your body. Second, iron is directly involved in cellular energy production itself. When iron stores run low, oxygen delivery and energy production both suffer — which is exactly why fatigue is often the first and most noticeable sign that something is off.
Why It's So Common, Especially in Women
Iron deficiency is one of the most widespread nutritional shortfalls, and women are disproportionately affected for a few clear reasons:
- Monthly menstrual blood loss represents an ongoing, recurring iron demand that men simply don't have
- Pregnancy dramatically increases the body's iron requirements to support both mother and baby
- Plant-based and largely plant-based diets, while offering many benefits, provide non-heme iron, which is less readily absorbed by the body than the heme iron found in animal sources
Signs Worth Paying Attention To
Low iron can show up in a variety of ways, and it's worth stressing that these signs are common to many conditions — they're a prompt to investigate further, not a diagnosis in themselves. Keep an eye out for:
- Persistent fatigue that doesn't improve much with rest
- Pale skin, particularly noticeable in the face or inner eyelids
- Breathlessness during activities that didn't used to leave you winded
- Brittle, spoon-shaped, or easily breaking nails
- Hair thinning or increased shedding
- Difficulty concentrating or a persistent sense of mental fog
Getting More From Your Food
Not all dietary iron is created equal. Heme iron, found in red meat, poultry and fish, is absorbed far more efficiently by the body than non-heme iron from plant sources like legumes, leafy greens and fortified grains. If you're relying more heavily on plant sources, a couple of simple strategies can meaningfully improve how much iron you actually absorb:
- Pair iron-rich meals with a source of vitamin C, such as citrus fruit, peppers or berries, which significantly enhances non-heme iron absorption
- Avoid drinking tea or coffee too close to iron-rich meals, since the tannins they contain can inhibit iron absorption
Test, Don't Guess
Here's the part that's easy to overlook: iron is one of those nutrients where both too little and too much carry real risks. Supplementing blindly, and particularly doing so long-term without knowing your actual levels, isn't something we'd recommend. The far safer and more effective approach is confirming where you actually stand through proper testing, so that any support you take is genuinely appropriate for your body.
