As a menopause coach and counsellor, I often hear women describe the unsettling experience of brain fog — forgetfulness, trouble concentrating, and mental fatigue. While hormonal changes are usually blamed, new research from the University of Oklahoma sheds fresh light on another important factor: low iron levels.
Published in Nutrients (2024), the study explored how iron status affects cognitive function in midlife women. Researchers measured systemic iron levels, conducted brain imaging, and assessed cognitive performance using EEGs during tasks. Interestingly, they found that higher systemic iron levels were linked to better brain function — without an increase in harmful brain iron deposits often associated with dementia.
This is a significant finding because it suggests that addressing iron deficiency may ease brain fog symptoms, without raising the risk of cognitive diseases like Alzheimer’s. It opens a critical new avenue for supporting women’s brain health during the menopausal transition.
Why does supplementing iron during menopause matter?
Iron plays a vital role in oxygen delivery to the brain, neurotransmitter production, and energy metabolism. Low iron can disrupt these processes, resulting in poor memory, slower thinking, and mental exhaustion — all common complaints during menopause.
While menstruation-related iron loss lessens after menopause, not all women automatically recover optimal iron stores. Diet, absorption issues, or prolonged low intake can still leave women vulnerable.
Practical steps to support brain health:
Check your iron levels. If you’re experiencing brain fog, ask your doctor for a blood test.
Eat iron-rich foods like red meat, lentils, spinach, and fortified cereals.
Pair iron with Vitamin C (think: spinach salad with oranges) to boost absorption naturally.
Be cautious with supplements. Too much iron can be harmful; always seek medical advice before supplementing.
This new research reminds us that menopause symptoms are often multi-faceted. Hormones, nutrition, and lifestyle all interact.
By considering iron as part of a holistic menopause strategy, we can better support cognitive clarity, energy, and overall well-being.
Menopause doesn’t have to mean living with brain fog. With the right knowledge and a proactive approach, women can reclaim their sharpness and confidence during this powerful life stage.
