Ferritin & Fatigue in Perimenopause: The Missing Piece Many Women Overlook
If you’re in perimenopause and feeling constantly tired, foggy, or easily depleted, one commonly overlooked lab marker to check is ferritin—your body’s stored form of iron.
Ferritin gives us a clearer picture than standard iron labs alone. You can have “normal” iron levels on paper, yet still have low ferritin, which can leave you feeling exhausted, short of breath, struggling with workouts, or even noticing hair thinning.
Why Iron Matters More in Perimenopause
During perimenopause, many women experience heavier or more frequent periods, which can gradually deplete iron stores over time. Add in busy lifestyles, stress, and inconsistent nutrition, and it’s easy to see how iron levels can quietly drop without obvious warning.
Are You Getting Enough Iron?
Low ferritin is often linked to not eating enough iron-rich foods. There are two main types of iron:
Heme iron (best absorbed):
Red meat (beef, lamb)
Dark meat poultry
Shellfish
Non-heme iron (plant-based):
Spinach and leafy greens
Lentils and beans
Tofu and tempeh
Pumpkin seeds
Quinoa
While plant-based sources are great, they’re not absorbed as efficiently as animal sources—so how you eat them matters.
The Coffee & Tea Mistake
One of the most common habits that can impact iron levels is drinking coffee or tea with meals. Compounds in coffee and tea can significantly reduce the absorption of non-heme iron (plant-based iron). If you rely on plant sources, try to avoid coffee or tea for about 1 hour before and after meals to support better absorption.
Simple Ways to Boost Iron Absorption
Pair iron-rich foods with vitamin C (like citrus, bell peppers, or strawberries)
Avoid coffee/tea around meals
Cook with cast-iron cookware (it can add small amounts of iron to food)
What’s an “Optimal” Ferritin Level?
Many labs consider ferritin levels as low as 15–20 ng/mL to be “normal,” but that doesn’t mean optimal—especially for women in midlife.
For many women, a ferritin level of at least 50 ng/mL is often associated with better energy, hair health, and overall well-being. Some practitioners even aim for levels closer to 70+, depending on symptoms and individual needs.
When to Consider Testing
If you’re experiencing:
Persistent fatigue
Low stamina or exercise intolerance
Hair shedding
Dizziness or brain fog
…it may be worth asking your provider to test ferritin (not just standard iron or hemoglobin).
The Bottom Line
Fatigue in perimenopause isn’t something you just have to “push through.” Sometimes, it’s your body signaling a deeper need—and ferritin is one simple, powerful place to start looking.
