Why You Probably Need More Creatine Than You Think

(And Why No One Ever Told You)

Let's start with a question. When you hear the word 'creatine,' what comes to mind? Probably something like: big dudes at the gym, protein shakes, maybe a little light grunting. Am I right?

Here's the thing — that image is outdated, and it has kept a lot of women from even considering creatine. Because creatine is not a bro supplement. It's a molecule your body literally makes on its own, and it plays a foundational role in how your muscles fire, how your brain thinks, and how your hormones manage energy across your entire life.

The reason you haven't heard much about creatine and women? Because most of the research — for decades — was done almost exclusively on men. Science has a bit of a gender gap problem, and creatine is one of its most glaring examples. But that's changing fast, and what researchers are finding is turning a lot of assumptions upside down.

Here's the Plot Twist: Women May Be Getting Less of It

This is where it gets genuinely interesting. Creatine comes mostly from meat and fish, and women tend to eat less of both. In a national U.S. survey of 4,522 women (NHANES 2017–2020), about 7 in 10 got less than the recommended 13 mg of creatine per kg of body weight from food each day, and intake fell with age.

The Science: A 2025 review in the Journal of the International Society of Sports Nutrition, 'Creatine in Women's Health: Bridging the Gap from Menstruation through Pregnancy to Menopause', describes how hormones affect creatine metabolism in women and calls for more female-focused research.

What this means practically: many women may be starting with less creatine from food, and hormonal life stages (periods, pregnancy, perimenopause and menopause) affect how the body handles creatine. Researchers are now studying what that means for energy, muscle and brain health.

So What Exactly Is Creatine Doing for You?

Think of creatine like a fast-charge battery pack for your cells. Your body uses something called ATP for energy — it's the universal fuel for everything from lifting a grocery bag to having a coherent thought at 3pm. Creatine helps regenerate ATP faster, which means your muscles can keep working harder during short, intense efforts.

The good news: creatine monohydrate is one of the most studied and most affordable supplements ever researched. A 2025 analysis of 685 clinical trials with about 13,000 participants (Kreider et al., Journal of the International Society of Sports Nutrition) found side effects were reported about as often with creatine as with placebo (13.7% vs 13.2% of studies).

But Won't I Get Puffy or Bulky?

This is the myth that has kept women away from creatine longer than anything else, so let's put it to bed properly.

Yes, creatine draws water into your muscle cells. But — and this is critical — that's intracellular water. It lives inside the muscle, not under your skin. It is not the kind of 'water retention' that makes you feel bloated or puffy. A 2023 randomized trial (Moore et al.) looked at whether creatine shifts fluid from outside the cells to inside them across the menstrual cycle.

The Science: In that trial, women did not see a significant increase in body mass with creatine across the menstrual cycle. Some people do see a small change on the scale in the first weeks, which reflects water held inside the muscle. The GUMvees Creatine label notes that you may gain weight.

As for 'bulking'? Creatine doesn't build muscle on its own. It helps you do more work during training, which over time compounds into better results. Think: one or two extra reps per set, faster recovery between sets, and maintained intensity deeper into your workout. Over months, that compounds into real change — without turning you into someone you don't recognize in the mirror.

Who Should Be Paying Attention?

Short answer: most active women. But specifically:

Premenopausal and active women whose creatine needs fluctuate with their cycle (more on this in the next article).

Pregnant women: researchers are studying creatine's role in pregnancy, but most of the evidence so far comes from animal studies (Tran et al., 2021), so this is not a reason to start a supplement. If you are pregnant or breastfeeding, talk to your health care practitioner before using creatine, as the GUMvees label advises.

Women in perimenopause going through the hormonal changes that affect sleep, focus and muscle, an active area of creatine research.

Postmenopausal women for whom declining estrogen speeds up muscle and bone loss. Creatine combined with resistance training is being studied for its effect on muscle and bone in this group.

The bottom line: creatine isn't a niche supplement for a niche person. Most women in the U.S. survey data were not getting the recommended amount from food, and researchers are actively studying what that means across a woman's life. GUMvees Creatine is Health Canada licensed (NPN 80126442) to increase muscle mass when used with resistance training and to improve strength in short, high-intensity activity.

In the next article, we're going to get into the menstrual cycle and why your relationship with creatine is more dynamic — and more important — than you probably ever realized.
