I'll be honest — creatine wasn't on my radar for years. When I heard the word, I pictured gym bros loading up before leg day. Not something I'd fold into my morning routine.
What changed my mind was brain fog. The kind where you sit down to focus and your head just… won't cooperate. Between work stress, life in general, and (let's be real) age creeping in, my brain kept being the thing that gave out first. So I started digging, and creatine kept showing up in places I didn't expect.
The wellness reframe
Creatine is a compound your body makes on its own and stores mostly in your muscles. You get small amounts from foods like red meat and fish, but most of us don't get much from diet alone — which is why athletes have been supplementing with it for decades.
What shifted for me is that the research has moved beyond performance. Creatine supports cellular energy (ATP — the fuel currency of every cell, including brain cells), muscle strength, and cognitive function. That third piece is what pulled me in.
What the research actually says
Before I put anything in my body daily, I want to see the receipts. Here's what stood out when I read the peer-reviewed work — especially the studies on women, which have historically been underrepresented in supplement research.
The overall consensus. The International Society of Sports Nutrition's position stand on creatine calls it one of the most effective and well-studied supplements available, with benefits extending beyond exercise performance into recovery and healthy aging in both men and women.
For women specifically. A recent review in Nutrients — "Creatine in women's health: bridging the gap from menstruation through pregnancy to menopause" — documents that women tend to have around 20% lower creatine synthesis and 30–40% lower dietary intake than men, which may make supplementation especially relevant. The review points to positive effects on muscle strength and cognitive function across the female lifespan.
For the brain (both sexes). A 2024 systematic review and meta-analysis of 16 randomized controlled trials found creatine supplementation produced measurable improvements in memory, attention, and processing speed — with the effects appearing somewhat stronger in female participants.
For the bigger picture. A narrative review in Nutrients synthesizing the evidence for women, vegans, and clinical populations concludes that creatine monohydrate is the preferred form and supports both physical performance and cognitive function.
The research isn't perfect — effect sizes vary and more women-specific trials are still needed — but the pattern across the literature is consistent enough for me.
Why I'm picky about supplements
Years in cybersecurity trained me to default to "trust but verify." I apply the same mindset to anything I put in my body — and honestly, more so, because I'm on a blood thinner. Anything new gets run past my doctor before it lands on my counter.
On top of my own situation: the supplement industry in the US is largely unregulated. The FDA doesn't approve supplements before they hit shelves the way it does with medications. So between my own medical reality and a market full of shortcuts, the homework falls on us.
Here's what I look for, every time:
- Third-party testing. NSF certification means an independent lab has verified what's actually in the bottle matches the label.
- Single-ingredient formulas. The fewer mystery additions, the better.
- No artificial sweeteners or fillers. If I'm taking it daily, I want it clean.
- A brand I can vet. How long have they been around? Where's it made? Who's behind it?
Most supplements fail at least one of those checks. A few don't.
What I picked: Naked Nutrition Creatine Monohydrate
After reading reviews, checking certifications, and running the brand past my usual skepticism, I landed on Naked Nutrition. It's 100% micronized creatine monohydrate (the form with the most research behind it), NSF certified and third-party tested, no artificial sweeteners or fillers, made in the USA by a company that's been around since 2014.
I grab the unflavored version because I mix it into things I'm already drinking. If you'd rather skip the mixing and have flavor built in, Naked also makes a Lemon Lime version held to the same standards — single-ingredient creatine plus real lemon juice powder for flavor instead of artificial sweeteners.
How I actually take it
One scoop (5 grams) a day. Where it goes depends on what I'm already drinking — most mornings it goes into my electrolyte drink, and on training days it gets stirred into my protein shake after a workout. The unflavored version disappears into both.
It's a daily habit for me, not a pre-workout ritual. That matters, because when you're juggling a lot, the last thing you need is another complicated routine to remember.
Who might want to skip this
Creatine is one of the most studied supplements on the market and is considered safe for most healthy adults — but it's not for everyone:
- If you have kidney issues or a history of kidney problems, talk to your doctor first.
- If you're pregnant or nursing, talk to your doctor before starting any new supplement.
- If you're on any prescription medications — I'm on a blood thinner myself — always run it by your doctor before adding something new. Even a well-studied supplement is new context for your body.
- If your current supplement routine is working for you, don't fix what isn't broken. More is not always more.
I'm not a doctor, and this isn't medical advice. I'm someone who did her homework and made a choice that fit her life. Your call is yours.
Bottom line
Creatine's reputation is shifting, and the research is catching up. It's well-studied, it supports energy, muscle, and cognitive function in both men and women, and it's affordable enough to fit into a daily routine without a second thought.
If you've been curious, here's the pick from the brand I use and trust: Naked Nutrition Lemon Lime Creatine.
Do better. Grow better. Live better. One small, sustainable habit at a time.
