Benefits of Creatine for cognitive sharpness in perimenopause.

Why Does Perimenopause Affect Cognitive Function?

Brain fog is one of those lesser-known perimenopause symptoms that can sneak up on you. In fact, many women report experiencing brain fog in some capacity during perimenopause (aka, the handful of years leading up to menopause) and beyond.

“Perimenopause is the stage of the menopause transition that precedes menopause. It can last 4-10 years on average. This is a time when women are having cycles - sporadically or regularly, and are experiencing menopausal symptoms. For some women, this can start in their 30s.” - Dr.Gandhi, MD MSCP

This mostly happens because of fluctuating and dropping estrogen levels, which can impact parts of the brain involved in memory and attention. 

If your understanding of brain fog is, well, a little foggy, here’s a clearer picture of what it can look like day to day: 

• Forgetfulness and losing your train of thought (for example, you might forget an old friend’s birthday or go into the kitchen on autopilot only to wonder what you walked in there looking for)

• Having a hard time concentrating or focusing

• Mental fatigue, which can show up as irritability, burnout, and not feeling motivated to do things 

On top of this, other common symptoms of menopause, like sleep issues and mood changes, can heighten brain fog even more. So, what do you do with all this?

On a positive note, research shows that brain fog is usually temporary, and subsides over time as you move through the stages of menopause and beyond. And more good news: There are many things you can do to manage it, from basic lifestyle habits to taking supplements like creatine, and exploring personalized medical care. Rest assured, you’ve got options. 

What Is Creatine and How Does It Work in the Brain?

Creatine is a naturally occurring derivative of an amino acid, and it plays a role in cellular energy production. Indeed, the brain needs it to maintain energy balance — even more so during periods of hormonal fluctuations.  

This is partly because women appear to have lower levels of creatine in their bodies, and changes in hormone levels (like fluctuating estrogen levels during perimenopause that then stay low once you reach menopause) can impact how creatine is metabolized. 

That’s where creatine supplements can enter the picture. 

If you’ve heard of creatine, it’s likely been within the context of muscle building and exercise. And it can indeed be helpful for those things. But emerging research shows that supplementing creatine could also increase its levels in the brain, and from there, possibly support greater mental clarity and focus.  

What Does the Research Say About Creatine for Cognitive Symptoms in Perimenopause?

One study found that supplementing with creatine increased creatine levels in women in perimenopause and menopause. It was also associated with faster reaction time, like how quickly your mind responds to something. This can show up in a few ways, such as feeling sharper in conversations, not needing to take a beat when you switch tasks, or processing what you’re reading quickly. 

The same study also suggests that supplementing creatine has some promise for improving both mood swings and lipid profiles. 

It’s also extensively researched in other contexts and is generally considered safe and well-tolerated in most people. 

All that being said, most studies so far have focused on women who are post-menopause. So more research is needed on using creatine supplements during perimenopause. 

With everything in mind, it might be a good option to add to your care routine during perimenopause in addition to other steps, like lifestyle changes and possible medical treatment if appropriate. Always make sure to discuss any supplement consumption with your clinicians. 

Can Creatine Help With Brain Fog, Memory, and Mental Fatigue?

Brain fog refers to a range of cognitive symptoms, and creatine hasn’t been studied in relation to all of them. It can help to understand which symptoms it might help with, and to identify which you’re experiencing, to see if it’s worth trying. 

So, here’s what it might help with: 

• Reaction time (how quickly you process information) 

• Attention and the ability to concentrate 

• How alert you feel or how motivated you are to do something 

• Mood stability and self-regulating emotional ups and downs 

On the other hand, things like retaining verbal information and memory aren’t necessarily impacted. 

Plus, there are a lot of factors at play in brain fog during perimenopause, from sleep issues to mood changes and stress. Creatine is a supplement and not a cure-all solution. Think of it more as an add-on tool to add to your menopausal toolkit.

It’s also a good time to remind you that most women experiencing symptoms like these still stay within normal cognitive limits — even if they notice changes, which can be reassuring. 

Is Creatine Safe for Perimenopausal Women? Dosage and Practical Considerations

For healthy adults, the recommended daily dose for creatine is 5 grams a day. It comes in a few forms – gummies, capsules or in a powder that you mix into water or a smoothie. You can also have it with or without food, so it can slide into your current routine pretty seamlessly.

It’s generally considered safe and isn’t associated with major side effects. The small studies we have on creatine supplementation in women in perimenopause have not reported any severe adverse effects.

Still, some mild side effects can show up in some people, including:

• Mild upset stomach (nausea, bloating, and diarrhea) 

• Water retention 

Though most people tolerate it well and lots of experts and researchers think the benefits outweigh the risks, it’s always a good call to talk to a healthcare provider before adding creatine to your routine (or any supplements for that matter). Women with kidney disease, in particular, should speak to their doctors first. 

How Does Creatine Fit Into a Holistic Approach to Cognitive Health in Perimenopause?

Creatine is easy to add to your routine, and there seem to be benefits. But it’s also good to look at it as part of a broader strategy paired with getting enough exercise, eating a healthy diet, stress reduction practices, and prioritizing sleep quality. 

Our nutrition, in particular, can influence cognitive function. Focus on getting these key nutrients to support your brain: 

1. B vitamins. B vitamins are important for energy production and brain function, particularly for people who are deficient. For people with adequate levels of B vitamins, though, they haven’t been linked with improving cognitive symptoms.

2. Magnesium. Another important supplement during perimenopause, magnesium plays a role in nerve function, sleep, and stress regulation. Because of this link, certain types of magnesium supplements might indirectly help with symptoms of brain fog. But current evidence doesn’t show a direct effect on brain fog itself.

3. Omega-3 fatty acids. Omega-3s are well known for their role in cognition and overall brain health. You can get them from supplements like fish oil and flaxseed oil, which have been studied for mood and aging, and some of the research is promising. Still, there is little evidence showing Omega-3s improve brain fog, in particular. 

4. Soy isoflavones. These plant-derived compounds might help manage hot flashes, which is why they’re commonly recommended for women in perimenopause and menopause. That said, when it comes to memory or cognitive function specifically, studies have not shown consistent benefits.

Fun fact – you can get all of these nutrients from food: 

• Soy products (tofu, tempeh, and soybeans)

• Salmon, mackerel, and avocado 

• Nuts, seeds, leafy greens, and legumes 

• Yogurt, eggs, and chicken 

Working with a provider to develop a personalized care plan with all your individual preferences and medical info in mind, and the most effective way to manage symptoms of perimenopause. 

And, again, be sure to talk to a healthcare professional before starting creatine.

When to Seek Help: Personalized Menopause Care for Cognitive Symptoms

It’s normal to experience some degree of forgetfulness and feel low energy from time to time during perimenopause. But when it starts disrupting your day-to-day functioning, it is time to reach out to a healthcare provider. 

A clinician can step back and look at the whole picture. This could involve screening for other issues, like thyroid changes, anemia, sleep disorders, mood conditions, or nutrient deficiencies that can affect cognitive function. From there, you can talk through a range of options, whether that’s adjusting daily habits, considering creatine supplements, or exploring medical therapies. 

Menopause hormone therapy (MHT) might also be part of that conversation. There’s some evidence that MHT could support aspects of cognitive function (though research is still evolving). Essentially, by addressing hormonal changes during perimenopause or menopause, MHT can also ease related symptoms like sleep issues and mood changes. 

If you think you are experiencing symptoms of perimenopause, there is no need to suffer. An early, personalized approach helps ensure that any medications, supplements, and lifestyle strategies are aligned — and actually working together for your needs.

If you’re ready for support, Alloy can connect you with a menopause-trained clinician today. They’ll offer science-based knowledge, evaluate your symptoms, answer your questions, recommend evidence-based treatments, and provide ongoing care and lifestyle support. 

Frequently Asked Questions

Why does perimenopause cause brain fog and forgetfulness?

Brain fog in perimenopause is primarily driven by fluctuating and declining estrogen levels, which directly affect areas of the brain responsible for memory and attention. This transition can lead to forgetfulness, difficulty concentrating, and mental fatigue. Furthermore, other common menopause symptoms like sleep disturbances and mood shifts can exacerbate these cognitive challenges, making it harder to stay motivated and focused.

How does creatine help with cognitive function during the menopause transition?

Creatine is a derivative of an amino acid that supports cellular energy production, particularly in the brain. Because women naturally have lower creatine levels and hormonal shifts can disrupt how it is metabolized, supplementation can help restore energy balance in the brain. Research suggests that creatine may improve reaction time, mental sharpness, and attention, helping women feel more alert and motivated while stabilizing mood swings.

Is it safe for women in perimenopause to take creatine daily?

For most healthy adults, a daily dose of 5 grams of creatine is considered safe and well-tolerated. It is available in various forms, such as powders, capsules, and gummies, and can be taken with or without food. While some individuals may experience mild side effects like water retention or slight digestive upset, severe adverse effects are rare. However, it is essential to consult with a healthcare provider before starting, especially for those with existing conditions like kidney disease.
