You walk into a room and forget why. You reread the same sentence three times. You reach for a word that’s just… not there. If this sounds familiar, you’re not alone, and you’re not losing your mind.
This is midlife brain fog, and while it’s frustrating (and sometimes downright frightening), it’s also incredibly common. For many women, it’s one of the most disorienting symptoms of perimenopause and menopause.
The good news? You’re not stuck with it, and science is starting to show that the right nutritional support can make a real difference.
During perimenopause, your oestrogen and progesterone levels fluctuate wildly. These hormones aren’t just for fertility, they also play key roles in brain function, including memory, focus, and mental clarity.
Research suggests that as oestrogen declines, so too does our brain’s access to key neurotransmitters like serotonin and acetylcholine—both vital for sharp thinking and mood stability [1].
Layer in stress, sleep disruption, and nutrient depletion, and it’s no wonder many of us feel like we’ve misplaced our mental sharpness somewhere around 45.
While there’s no magic fix, certain vitamins and adaptogens have shown strong potential in supporting cognitive function, especially during hormonal transition.
At Eir Women, we’ve carefully selected evidence-based ingredients across our product range to target brain fog from multiple angles.
B Vitamins
Found in: Show Up
B-complex vitamins (especially B6 and B12) support neurological health, energy production, a nd the creation of neurotransmitters. Low levels have been linked to forgetfulness, fatigue, and mood changes [2].
In Show Up, we use activated, bioavailable forms so they can be absorbed and used efficiently by your body—especially if you have common gene variants like MTHFR.
Found in: Show Up
Ginkgo is one of the most studied natural ingredients for cognitive health. It’s known to support memory, focus, and circulation to the brain [3].
We include it in Show Up because it complements B vitamins and ginseng, creating a holistic formula for daily mental clarity.
Found in: Show Up
Unlike its more stimulating Asian cousin, American ginseng has been shown to enhance mental performance without the jitters. It supports focus, energy, and resilience under pressure—perfect for those mental dips mid-afternoon [4].
Found in: Show Up
Beyond immune support, vitamin C plays a role in neurotransmitter production and protects the brain from oxidative stress [5]. This is crucial during midlife, when hormonal changes can increase inflammation and sensitivity to stress.
Found in: Reboot
Brain fog isn’t just about memory, it’s also deeply tied to stress and sleep. Ashwagandha is a powerful adaptogen known to reduce cortisol, calm the nervous system, and support restorative sleep [6].
You’ll find therapeutic levels of ashwagandha KSM66 (the best) in Reboot, our formula for stress resilience and emotional balance.
Found in: Trimmed
Saffron has emerging evidence supporting its ability to boost mood, reduce anxiety, and enhance cognitive performance [7]. We include it in Trimmed, where its benefits for mental focus and emotional wellbeing complement its role in appetite and weight support.
We didn’t guess when we created our range. We consulted clinicians, combed through the research, and formulated supplements that speak directly to the needs of women in midlife.
Every supplement is TGA Listed, clinically dosed, and made with forms your body can actually use.
Brain fog in midlife isn’t “just getting older”, and it’s certainly not something you have to accept.
With the right nutrients and a supportive, evidence-based approach, you can reclaim your clarity, your calm, and your confidence.
At Eir Women, we’re here to help you not just survive this chapter, but to feel like yourself again. Only sharper, stronger, and fully supported.
