This post is about a supplement. I'm not a dietitian or nutritionist, and nothing here is medical advice. If you have an existing health condition or are on medication, please speak to your doctor before adding any supplement to your routine.
Creatine is a compound your body makes from amino acids — specifically in your liver, kidneys, and pancreas. Its job is to store energy inside your cells, particularly in muscle and brain tissue. It's been one of the most researched supplements in the world for decades, but almost all that research was done on men. That's finally starting to change, and what's coming out is genuinely interesting for women.
First: why women start with less
Women naturally have lower creatine stores than men. Your body produces about 1–2g per day on its own, and you get another 1–2g from food — mainly red meat and fish. That's your total supply. And while that sounds like it adds up, women tend to start from a lower baseline, which means the gap between what you have and what your body could use is wider than it is for men.
This also means that if you eat a mostly plant-based diet, you're getting very little creatine from food at all — because it's almost exclusively found in animal muscle tissue.
Reason 1: Metabolic health
Creatine supports better blood sugar control, helps preserve muscle mass, and supports energy production at a cellular level. More muscle generally means a more responsive metabolism. And when your cells have the energy they need, you feel it — in how you train, how you recover, and how you feel day to day.
More muscle. Faster metabolism. Better energy.
Reason 2: Hormonal health
This one surprised me. Estrogen actually affects how your body uses and stores creatine. So as estrogen drops during perimenopause and menopause, creatine levels may also decline alongside it. That's a double hit at exactly the stage of life when preserving muscle and energy becomes more important.
Creatine combined with strength training has been shown to support body composition in perimenopausal and postmenopausal women. Your hormones change. Your nutritional needs change with them.
Reason 3: Brain health
Here's the part most people don't know: creatine doesn't just live in your muscles. It's also stored in your brain — and women have lower creatine levels in the brain than men, specifically in the frontal lobe. That's the area responsible for mood, memory, cognition, and emotional regulation.
According to the slides, creatine improved brain energy, focus, and emotional balance in women within 8 weeks. Your brain needs creatine too — not just your biceps.
Reason 4: Longevity
Healthy ageing starts long before you feel 'old.' Creatine helps preserve muscle and strength as you get older, may support bone health when combined with strength training, and supports brain energy and cognitive health over time. These are exactly the things that make the difference between feeling vital in your 50s, 60s, and beyond — and not.
Creatine supports how you age.
- Writing it off as a bodybuilder supplement — creatine has benefits far beyond the gym, especially for brain health and longevity.
- Not taking it consistently. Creatine works by saturating your stores over time, so skipping days regularly means you never get there.
- Worrying about bloating and stopping before giving it a real chance. Some people notice mild water retention early on; it usually settles.
- Assuming food alone is enough. If you eat little or no red meat or fish, your dietary creatine is likely very low.
- Waiting until menopause to think about it. The hormonal link means it's worth understanding creatine well before that transition begins.
If creatine is something you're curious about, start by doing a bit of research into creatine monohydrate — it's the most studied form. Then, if it feels right for you, bring it up with your GP or a registered dietitian to talk through whether it makes sense for your situation specifically.
