For years I had the same reaction most women have when creatine comes up: that is a men's supplement, it causes bloating, it is for people who lift heavy things competitively, and it has absolutely nothing to do with my life. Every single part of that was wrong. The research changed my mind. What happened after I started taking it kept it changed.
What I got wrong — and why most women do
Creatine became associated with a very specific image: young men at the gym, protein shakes, bulk. That association was so persistent and so thoroughly marketed that it became almost impossible to see past it. I certainly did not try. I filed creatine under "not for me" so quickly and completely that I never went back to question it.
What I did not know — and what most women do not know — is that women naturally store significantly less creatine than men. Around 70 to 80 percent less, depending on the source. Which means women start from a lower baseline and have proportionally more to gain from supplementation. The research specifically on women, and particularly on women during perimenopause, is some of the most compelling in the supplement literature. None of it appeared in the bodybuilder marketing I had unconsciously filed creatine under.
I started paying attention when I kept seeing it referenced in research on perimenopause and muscle health. I read more. I started taking it. I am now consistently surprised it took me this long.
"I thought I would never take creatine — that is going to blow me up. But no, girl needs that. It helps with brain fog."
— Halle Berry, The Run-Through with Vogue podcast, February 2026Why creatine becomes more relevant
after 35, not less
Starting in the mid-30s and accelerating after 40, the body begins losing muscle mass at a rate of roughly three to eight percent per decade — a process called sarcopenia. This is not a failure of willpower or effort. It is a physiological shift driven by declining oestrogen levels, reduced anabolic hormone production, and changes in how efficiently the body synthesises protein. The things that worked for your body at 28 genuinely become less effective, not because you are doing them wrong, but because the underlying biology has changed.
Muscle mass lost per decade starting in the 30s. After menopause that rate can accelerate significantly — making the decade between 35 and 45 the most important window to build and protect what you have.
Journal of Cachexia, Sarcopenia and Muscle; Baumgartner et al.; multiple peer-reviewed sourcesCreatine directly addresses this. When combined with resistance training — which is the other non-negotiable after 35 — creatine supplementation helps preserve and build lean muscle in a way that becomes increasingly difficult without it as hormones shift. For perimenopausal and menopausal women specifically, the research is particularly strong. This is not a supplement for young male athletes. It is a supplement that matters more the older and more hormonal the picture becomes.
It also matters for reasons that have nothing to do with the gym. The brain benefits are what most women I know find most surprising — and most immediately relevant.
What the research actually shows
Muscle mass and strength
The most established benefit. Creatine increases the muscles' stores of phosphocreatine, which helps regenerate ATP — the energy currency muscles use during effort. Studies consistently show that women who combine creatine with resistance training gain more lean muscle than those who train without it. Critically: creatine does not cause the bulky muscle development women fear. Women lack the testosterone levels required for that effect. What it does cause is stronger, more functional muscle — which after 35 is one of the most protective things you can invest in.
Brain fog and cognitive function
This is the benefit that surprised me most, and the one most relevant to women in perimenopause. Creatine is not just stored in muscle — it is also stored in the brain, where it plays a role in energy metabolism. Research shows it may support cognitive function, reduce mental fatigue, and improve memory recall. Halle Berry specifically cited it for the brain fog she experienced during menopause. If you are in your 40s or 50s and have noticed your thinking feels slower or less sharp than it used to, this is worth understanding.
Bone health
Oestrogen plays a central role in maintaining bone density. As oestrogen declines, that protection diminishes — which is why osteoporosis disproportionately affects women, and why the perimenopausal years are such an important window for bone health interventions. Research suggests creatine combined with resistance training may support bone geometric properties (the structural strength of bone) and help reduce the risk of falls and fractures — not by replacing calcium or vitamin D, but by enhancing the muscle strength that supports the skeleton.
Mood and energy
Some research suggests creatine may reduce symptoms associated with depression in women — you may want to verify this with current literature as this area is still developing. The energy benefits are more established: creatine improves the efficiency of how the body produces cellular energy, which over time contributes to reduced fatigue and better performance across physical and cognitive tasks. For women experiencing the energy decline that often accompanies perimenopause, this is a meaningful and underappreciated benefit.
Creatine is one of the most extensively researched supplements in existence. Creatine monohydrate specifically has decades of safety and efficacy data behind it. Women with kidney or liver disease, or those on related medications, should speak with their doctor before supplementing. Its safety profile during pregnancy has not been sufficiently studied, so it is not recommended during pregnancy. For the broad majority of healthy adult women, the safety evidence is among the strongest of any supplement category.
What I noticed when
I actually started taking it
I want to be clear that individual results vary and I cannot promise you will experience what I did. What I can tell you is what happened for me — honestly, without overstating it.
The first thing I noticed, within about two to three weeks of taking these gummies daily, was that my workouts felt different. Not dramatically different — not a sudden transformation — but a measurable improvement in how many repetitions I could complete before fatigue, and how quickly I recovered between sets. It was subtle enough that I almost dismissed it. Then I noticed it was consistent, not a good day.
The second thing, which took longer and surprised me more, was the mental clarity. The specific brain fog I had been attributing to perimenopause — the mid-sentence word loss, the slower processing — improved noticeably over about six to eight weeks. I had not expected that. When I went back and read the research on creatine and cognitive function in perimenopausal women, I understood why it had happened. I just had not connected the dots until I experienced it.

the practical guide
Form: Creatine monohydrate is the most researched, most effective, and most affordable form. Any product claiming to be "superior" to monohydrate requires scrutiny — the evidence base for monohydrate is simply not matched by newer formulations.
Dose: 3 to 5 grams daily is the standard recommendation for women. There is no meaningful benefit to taking more than this, and it is not necessary to do a "loading phase" — starting at 3 to 5 grams daily and maintaining it consistently works just as well over time.
Timing: Timing matters less than consistency. Take it at whatever point in your day you will actually remember it — with food, in your morning routine, after a workout. Consistency over weeks and months is what produces results, not the specific hour.
Hydration: Creatine draws water into muscle cells, so adequate hydration is important. If you are not already drinking enough water — and most people are not — this is the moment to address that.
The fears that kept me
from starting — addressed honestly
This is the most common and most persistent misconception. Bulky muscle development requires testosterone levels that women do not have. What creatine produces in women is stronger, more functional muscle — which visually reads as leaner, not larger. The scale may go up slightly in the first week or two as muscles retain water (this is normal and not fat gain), but this stabilises quickly. Almost every woman who initially feared this response reports the opposite experience to what they expected.
This concern originated from early research that has since been substantially revised. For healthy adults without pre-existing kidney disease, decades of research have found creatine supplementation at standard doses to be safe. If you have kidney disease or are on relevant medications, speak with your doctor first. For healthy women, the kidney concern is not supported by current evidence — you may want to verify this with the latest published research or your own medical team.
The muscle and strength benefits are amplified by resistance training — so if you train, you will see more. But the cognitive benefits, the bone health support, and the cellular energy benefits operate independently of training intensity. Women who do moderate exercise, walking, Pilates, or lighter strength work still derive meaningful benefit. You do not need to be training hard for creatine to be relevant to you after 35.
Bloating and digestive discomfort are most commonly associated with the loading phase — taking higher doses (20g+) for the first week, which was a common older protocol. Starting at a standard 3 to 5 grams daily from the beginning largely eliminates this. The gummy format is particularly well-tolerated for those who find powder difficult.
The two forms I recommend —
and what to look for
My preferred format — not because gummies are inherently superior but because I actually take them consistently, which is the only metric that matters. No powder, no taste, no remembering to mix anything into water. I take mine in the morning with my other supplements. For anyone who has struggled with consistency on powders, the gummy format changes the equation entirely.

The water retention in muscle happens within the first week and is the first physical sign. Strength and performance improvements typically become apparent within two to four weeks of consistent daily use. Cognitive benefits — if you experience them — tend to take longer, usually four to eight weeks. The most important thing is not to judge it in the first two weeks and then stop. Give it eight weeks at minimum before drawing conclusions.
Yes. The cognitive, bone health, and cellular energy benefits do not require gym-level training. If you walk regularly, do Pilates, swim, or do any form of consistent movement, you will still derive meaningful benefit. Resistance training amplifies the muscle-specific results, but it is not a prerequisite for creatine to be worth taking after 35.
The research does not support cycling as necessary. Your muscle creatine stores will gradually return to baseline if you stop taking it, which means stopping and restarting means repeatedly going through the saturation period. Current evidence supports consistent daily use rather than cycling.
No — the research supports benefits across the full spectrum of menopause stages. Some of the strongest evidence for creatine and muscle preservation in women is specifically in postmenopausal women, where the loss of oestrogen's protective effect on muscle and bone is most significant. If anything, it becomes more relevant, not less, after menopause.
Generally yes — creatine does not have significant negative interactions with the most common supplements women take. I take mine alongside magnesium, vitamin D3, collagen and protein. As always, if you are on prescription medications or have specific health conditions, check with your doctor first. I cover my full supplement stack in the supplements post.
I spent years dismissing a supplement that the research is unambiguous about for women in exactly my situation. I am not going to tell you how long you have been missing out on it — that is for you to discover. What I will say is that if you have read this far, you already know enough to make a decision. Start with 3 grams daily and give it eight weeks of honest consistency. Then tell me what you noticed.
