The first randomised control trial looking at creatine supplementation for peri-menopausal and menopausal women (Full disclosure I wrote both the blog and this a while ago, but this has ended up sat in drafts 🤦‍♀️).

Creatine is naturally occurring in the muscles and brain. It has a role in producing energy and has previously largely been researched for ergogenic (performance improving) effects in athletes. However, it’s increasingly of interest for other potential benefits including brain function and blood sugar regulation (although currently evidence is very limited).

This study to an increasing evidence base that creatine is a beneficial tool for mid-life women, with potential to improve both symptoms and clinical outcomes (although the stronger evidence exists around symptom relief at present).

⭐️Further, benefits to maintaining muscle mass and reducing fatigue may support women in peri-menopause and menopause to continue participating in their sport and engaging in regular physical activity. Which we know to be important for bone health and overall wellbeing.

A separate recent review (PMID: 40198156) suggests creatine to be a safe and well tolerated dietary supplement - although this is largely based on short-duration studies amongst athletic populations.

Overall, food first approaches are always best but the evidence for creatine as a valuable adjunct is increasing. That said - more evidence on dosing and longer term studies with larger, more diverse samples are needed.

Here’s a bit of insight into what to expect ☝️

As 2025 winds down, I just want to say a brief but very heartfelt thank you to everyone who’s supported me in this venture this year - whether clients, friends/family or other services/professionals.

It’s been a real positive of the year for me (and also a steep learning curve on the business side that I’m still trying to navigate!).

It’s also been such a privilege to be a small part of people’s journeys and see the progress made - although you’ve done the hard work in putting advice into practice so I can’t take credit for that!

2026 👉 let’s go

Three years ago, this time of year would’ve had me finalising a race calendar and deep in the data, mapping out how to build. This year, when I sat down to think about goals, they look very different.

From a sports perspective, my main aims right now are to keep giving injury rehab my best shot—and to be able to get up off the floor well enough to go paddle boarding come spring (or even summer).

I initially caught myself prefacing those goals with “just.” But actually, they’re just as valid and important to me as big race events. If anything, they’re probably harder to achieve—because, frankly, current rehab is dull, painful, and I don’t honestly know what the end outcome will be. It’s just me, for me.

The point of this is that your goals have to meet you where you’re at—and be realistic for you as an individual.

Making changes is hard. And food plays so many roles in our lives—physical, social, emotional—that changing how and what you eat can feel especially challenging.

If you’re looking to adjust how you fuel or what your diet looks like, I’d encourage you to think about goals that are clear, achievable, and focused on what you can actually do day to day, rather than a distant end point.

Smaller, achievable steps that progress gradually are far more sustainable than going all-in and ending up overwhelmed. Maybe that looks like fuelling key sessions first—starting with morning workouts. If 30g of carbs feels like too much, start with 15g. Want to eat more carbohydrate overall? Begin with one meal and build from there.

Small steps still count.
Meet yourself where you are—and celebrate the little things (I'm still learning this one myself!).

Christmas can amplify food noise - and there’s a tricky juxtaposition between the messages of indulgence, swinging into the (unnecessary) ‘new year, new you’ focus.

This can exacerbate challenges if your relationship with food or exercise is already complex. Even if it’s not, the change in routine and structure can be uncomfortable for many.

Remember:
✨you’re allowed to eat (and enjoy it)
✨you don’t owe anyone an explanation
✨Be mindful - keep in touch with your own priorities and needs
✨your body will likely benefit from some extra recovery time - don’t try and ‘cram in extra’ to compensate (it’s just a short time, overdoing it won’t benefit performance but might risk injury/illness)
