Recent research shows that menopause impacts more than just hormones, sleep, and energy - it can also alter the very structure of the brain. A major UK study involving nearly 125,000 women found that post-menopausal women show significant reductions in grey matter - the part of the brain essential for memory, emotional regulation, attention, and movement. These changes were most noticeable in areas like the hippocampus and anterior cingulate cortex, regions also implicated in Alzheimer’s and other cognitive conditions.
Why this matters
Grey matter plays a central role in how we think, remember, and process the world around us. The study found that, on average, women after menopause had lower grey matter volume in these critical regions compared with pre-menopausal women. This may help explain why women are diagnosed with dementia at higher rates than men - roughly two-thirds of Alzheimer’s cases are women.
Importantly, this doesn’t mean that every woman will develop dementia - but it does underscore that menopause is a time of real neurological change, not just hormonal fluctuation.
The connection with “brain fog”
Many women in perimenopause and menopause report symptoms like difficulty concentrating, memory lapses, and feeling mentally slow - commonly referred to as “brain fog.” These frustrations are real and can have a noticeable impact on daily life, even if they’re not a sign of dementia itself. Studies show cognitive complaints like these are common and often linked to the broader changes happening in the brain around this time.
Sleep disruption, mood changes, and fluctuating hormone levels - all typical during menopause - can intensify these symptoms. So while the link between menopause and brain structure doesn’t equate directly to cognitive disease, it does reinforce that the brain is affected in meaningful ways during this transition.
The power of nutrition
So what can you do about it? Nutrition is one area where many women find meaningful support. One nutrient that is particularly important during perimenopause and menopause is iodine - an essential mineral the body cannot produce on its own. It plays a key role in thyroid hormone production, which in turn supports metabolism, energy levels, and yes - cognitive function.
Iodine deficiency is surprisingly common, especially in parts of Europe and North America where iodine-rich foods like seaweed and seafood are not eaten regularly. Ensuring adequate intake can help maintain normal thyroid function and support your body during hormonal transitions like menopause.
Introducing the Menopause Support Duo
To help women navigate these changes naturally, we developed Doctor Seaweed's Menopause Support Duo.
This powerful combo pairs two award-winning products:

Focus+, a dual capsule contain a powder blend of iodine, B vitamins and zinc, plus a gel capsule of algae-derived Omega-3 DHA.
Together, they help you manage common symptoms like brain fog, fatigue, and low energy, while supporting hormonal balance and overall well-being.
The Menopause Support Duo works to support your body on multiple levels. Phytoestrogens and B vitamins help regulate hormone levels more smoothly, easing common menopausal symptoms like hot flushes and mood swings. Iodine and B vitamins also play a key role in energy metabolism, helping your body convert food into usable energy to combat fatigue and tiredness. At the same time, Omega‑3 DHA from algae, along with essential micronutrients, supports brain health, focus, and memory, helping you feel mentally clearer and more alert.
Together, these nutrients create a simple, natural daily routine that supports your body and mind during a major life transition, particularly if you’re dealing with brain fog, low energy, or shifts in metabolism.
