You’re not crazy. You’re not lazy. And no, you’re not just "getting older." If you’re dragging through your days, feeling foggy, heavy, or worn out—but your labs are "normal"—you’re not alone. One of the most overlooked causes I find in my practice is suboptimal ferritin levels. Let’s break it down—with science, a little wit, and a whole lot of hope. Your Body: A High-Performance Machine Imagine your body like a beautifully engineered, high-performance car. Hormones are your spark plugs. Micronutrients are your engine oil. Proteins are your gears and pulleys. Without the right balance of all these building blocks, the engine sputters. It doesn’t matter how good the outside looks—if you're low on fuel or missing key fluids, you’re not getting out of the driveway. And iron —stored as ferritin—is a huge part of that fuel system. What Is Ferritin, and Why Should You Care? Ferritin is your body's iron storage protein. It’s like your gas tank. Not your current speed, not your miles per gallon—your actual reserve of fuel. Iron is essential for carrying oxygen to every cell in your body. It's crucial for energy production (ATP) in your mitochondria. It supports your thyroid, neurotransmitter function, hair growth, immune system, and even mood. If you’re low on ferritin, you might still show " normal " hemoglobin or hematocrit—so traditional screening won’t catch it until you’re running on fumes. Symptoms of suboptimal ferritin can include: Fatigue and poor exercise tolerance Brain fog or poor concentration Mood swings or low mood Headaches Hair shedding Shortness of breath with minimal exertion Restless legs or poor sleep Sound familiar? But My Labs Say I'm Normal... Here's the kicker: most lab ranges are designed to flag anemia — not optimal function. You could have a ferritin of 12 and be told " everything looks fine " — but feel absolutely awful. For most women, especially those who are still menstruating or recently stopped, ferritin levels under 40–60 ng/mL can cause symptoms . Many functional and integrative medicine specialists aim for 70–100+ ng/mL to support optimal energy, cognition, and hair health. Low-normal is not optimal. When your engine light is blinking, topping off the tank halfway doesn’t cut it. Why You Might Be Low Menstruation: Every period can deplete iron stores, especially if cycles were heavy. Pregnancy and postpartum: Even years later, many women never rebuild their iron stores. Gut health issues: Poor absorption due to low stomach acid, celiac disease, or IBS. Dietary patterns: Plant-based diets can be low in easily absorbed heme iron. Chronic inflammation: Inflammatory signals can "hide" your iron from circulation. Food First, But Realistic Yes, food matters. Red meat, poultry, seafood, lentils, spinach, and pumpkin seeds all contribute iron. But rebuilding storage? That’s a bigger lift. Think of dietary iron like filling up your gas tank 10–15% at a time. Helpful, but slow if you're starting on empty. Sometimes you need a boost. That’s where targeted supplementation can help—whether it’s gentle oral iron (like iron bisglycinate) or occasional intravenous iron if needed. And by the way, ever wonder why "senior" vitamins have no iron? Because postmenopausal women typically don’t lose blood monthly. We don’t want too much iron. But we also can’t function with too little. Balance is everything. Final Thoughts If you’re feeling run down, foggy, achy, or unlike yourself—it’s not "all in your head." Your body is whispering (or screaming) for better support. And sometimes the missing piece isn’t fancy. It’s basic, foundational, and fixable. Ferritin matters. Iron matters. You matter. At Wondercreek Health, I believe in digging deeper, connecting the dots, and helping you rebuild the strong, steady foundation your body deserves. Because you weren’t designed to run on empty. Iron-Rich Foods to Boost Your Levels Beef, lamb, liver (heme iron is best absorbed) Dark poultry (chicken thighs, turkey) Shellfish (clams, oysters, mussels) Lentils and chickpeas Spinach and swiss chard Pumpkin seeds and cashews Fortified cereals and oatmeal Tofu and tempeh Tip: Pair iron-rich foods with vitamin C (like bell peppers, oranges, or strawberries) to boost absorption! Ferritin Target Chart Ferritin Level What It Means <15 ng/mL Severe deficiency 15–40 ng/mL Low stores (symptoms likely) 40–60 ng/mL Borderline (may still have symptoms) 70–100+ ng/mL Optimal for energy, cognition, hair health Individual needs vary—always interpret ferritin in the context of your full health picture! When to Suspect Low Iron Feeling tired despite good sleep Exercise feels harder than it used to Brain fog or poor memory Unexplained hair thinning Pale skin or brittle nails Frequent headaches Restless legs or poor sleep Shortness of breath climbing stairs If you’re nodding along to several of these, it’s worth a closer look at your ferritin levels.
