Creatine for Women in Perimenopause — What a Physical Therapist Wants You to Know
TL;DR: A PT's honest take on creatine for women in perimenopause — the research on muscle, bone health, and brain fog, plus what to look for in a supplement.
Creatine is one of the most researched supplements available — and the research specifically for women in perimenopause is growing and genuinely promising
When combined with resistance training creatine supports meaningful gains in strength and muscle mass in older women
Emerging research suggests benefits for bone health and cognitive function — including memory, attention, and brain fog
The research is still building — these are promising findings not guarantees

I Walked Into the Kitchen and Completely Forgot Why
I stood there for a full 30 seconds trying to remember what I came in for.
I have been mid-sentence and lost the word I was looking for. I have opened my phone to do something specific and immediately forgotten what it was.
I have two and a half year old twins. I run a business in the cracks of time. I work as a physical therapist in senior living communities. And I am likely navigating perimenopause.
So is it mom brain? Perimenopause brain? Just life?
Probably all three. But here is what I know — I am not as sharp as I used to be. And as a PT who spends a lot of time thinking about what we can do proactively for our health in our 40s and 50s — I wanted to do something about it.
That is what led me to finally prioritize creatine.
I Already Knew About Creatine — I Just Never Prioritized It
As a physical therapist creatine has always been on my radar for muscle and bone health. The research on creatine for athletic performance and muscle mass has been robust for decades.
What I had not paid as much attention to was the emerging research specifically for women in perimenopause — particularly around cognitive function. When I started looking at that more closely it became clear that now was the right time to start.
Here is what the evidence actually shows.
What the Research Says About Creatine for Women in Perimenopause
Muscle and Strength
Women can expect to lose 3-5% of their muscle mass per decade starting in their 30s — and this loss accelerates after menopause. Because muscle is metabolically active this contributes to a slower metabolism, changes in body composition, and reduced functional strength.
The research on creatine and muscle in older women is among the strongest available. A 2021 systematic review and meta-analysis of randomized trials in older females found that adding creatine to resistance training produced significant gains in strength versus training alone — especially in programs lasting 24 weeks or more.
The key detail: resistance training plus creatine. Not creatine alone. The combination is what drives the results.
Bone Health
A two year randomized controlled trial examined the effects of creatine monohydrate supplementation and exercise on bone health in postmenopausal women — with femoral neck bone mineral density as the primary outcome. This is one of the most fracture-vulnerable sites in women navigating perimenopause and beyond.
As a PT focused on bone health this research matters to me. Creatine alongside resistance training — the work we are already doing — adds an additional layer of support.
Cognitive Function and Brain Fog
This is the piece that finally pushed me to prioritize creatine for myself.
A 2024 analysis of 16 clinical trials found that creatine may improve cognitive function — specifically memory, attention, and information processing speed.
A 2025 randomized controlled trial of 36 women in perimenopause or postmenopause found that 8 weeks of creatine supplementation improved reaction time and reduced mood swing severity.
Brain fog is a common symptom of perimenopause. The idea that creatine may support cognitive function — alongside everything else it does for muscle and bone — made this a clear decision for me.
An Important Note on the Research
Data on perimenopausal women specifically remains limited and future research should focus on optimizing dosing strategies and understanding long-term health implications.
I want to be honest — the research is promising but still building. These are not guarantees. They are findings that point in a compelling direction — particularly for women who are already prioritizing resistance training and bone health.
Why This Fits My Lane as a PT
I want to be clear about my scope here. As a physical therapist my expertise is in the musculoskeletal system — muscle, bone, strength, and function. Creatine's benefits for muscle preservation, bone health alongside resistance training, and the emerging cognitive research all sit within or adjacent to that space.
I am not prescribing a supplement or advising you to take a specific dose. I am sharing what I have found in the research — and what I have personally decided to add to my own routine.
If you are considering creatine — please talk to your healthcare provider first. Especially if you have any underlying health conditions.
What I Am Using — and Why I Trust It
I recently started using Needed's Creatine — and I want to tell you specifically why I chose this brand.
Needed is a women's health supplement company whose formulations are research-backed and designed specifically for women's unique needs at every life stage. They are not a generic supplement brand. They are built around women — and that matters when it comes to formulation and dosing.
If you have been dealing with brain fog, fatigue, or feeling like you are running on fumes — and you are already doing or building toward resistance training — Needed's creatine is worth trying.

The Bottom Line
Creatine is not just a bodybuilder supplement. The research for women in perimenopause — across muscle, bone health, and cognitive function — is growing and genuinely promising.
Combined with resistance training it supports the work you are already doing. And for women navigating the cognitive symptoms of perimenopause — brain fog, fatigue, feeling less sharp than you used to — it offers a promising and low risk addition to your routine.
The research is still building. But what exists is compelling enough that I have personally made it a priority.
And if you are walking into rooms and forgetting why — you are not alone. I am right there with you. 💙
