Creatine for women: benefits for strength, brain health and hormones – without the bulk

Creatine has had a pretty fixed identity for most of its commercial life. It came in enormous tubs, it lived next to things called Xtreme Mass and Hyper Shred, and it was, for a very long time, something men bought before lifting heavy things. Most women never questioned whether it applied to them, and most brands never bothered to suggest that it might. But at some point, searches for creatine for women started climbing, and by 2025, Thorne, one of the supplement industry’s most credible names, had tapped Grammy-winning artist Ciara specifically to make the case that creatine wasn’t just for the guy with the bulk bag. Our body produces creatine naturally, stored in muscle and topped up through food. Women generally have lower total creatine stores than men, around 70 to 80 per cent less, a gap that, according to Dr Mark Kovacs, founder of the Kovacs Institute and former director of the Gatorade Sports Science Institute, “creates a scenario where women may have more room for improvement from supplementation”. That deficit is precisely the point. According to Jarman Gosai, strength trainer and founder of Gym Concoction in Melbourne, that lower starting point actually makes women more responsive to creatine supplementation. “It’s like a phone battery sitting at 30 per cent versus one at 70 per cent: the one at 30 per cent has more room to charge, so the boost from plugging the cord in is bigger,” Gosai says. What creatine is actually doing is replenishing ATP, the body’s primary fuel source, which muscles burn through almost instantly during high-intensity effort. “I usually like to think of creatine as the tool to increase the size of your ‘quick energy backup pool’ – the more you have of it, the longer your muscles will be able to tolerate intense repeated work,” says Marwa Ahmed, certified strength and conditioning expert and founder of The BodyMind Coach. What that usually means is better running times, heavier lifts or faster recovery between repeated sets. The gym case is pretty well-established at this point. But for most women, the hesitation is about what creatine might do to their bodies. The bloating, the bulk, the puffy look; a handful of specific fears tend to come up again and again, and they’ve followed creatine into the women’s wellness conversation for years. Starting with the bulk: building the kind of size typically associated with creatine use in men requires testosterone levels that women simply don’t have. “The low testosterone with the lower creatine baseline means the effects of creatine show up more as better recovery, higher performance or improved mood – more so than visible muscle gain,” says Ahmed. The water retention question is related but different. “Creatine primarily increases water inside the muscle cell, not underneath the skin,” says Kovacs. “This intracellular hydration is actually one of the mechanisms that may contribute to improved muscle function, recovery and adaptation. It is very different from the type of water retention people often associate with feeling puffy.” And the bloating complaints that do exist come almost entirely from loading phases, an entirely optional practice where, instead of taking the standard daily dose, you take around 20 grams a day for a week to saturate muscle stores quickly and get results faster. “Creatine is not particularly water-soluble – less soluble than table sugar, for reference – so at those volumes, some of it sits undissolved in your gut and draws water into your intestines through osmosis,” says Gosai, and that’s where the bloating, the puffiness and the one to two kilos of extra scale weight usually come from. Women who track their cycle and notice their performance dips in the second half of the month aren’t imagining it. During the luteal phase, when progesterone rises, the body’s reliance on carbohydrates for fuel drops and muscles lean more heavily on the creatine-phosphate system. Energy feels lower, workouts feel harder and there’s no obvious reason why. Although the research on whether supplementation can smooth that dip is still in its early stages, it’s pointing somewhere useful. A 2024 study, for example, found that women who got enough creatine through their diet had a significantly lower risk of irregular periods, and given that dietary creatine comes almost entirely from red meat and fish, vegetarians tend to have lower stores than most and may notice more of a difference from supplementing. And for anyone navigating perimenopause who’s noticed their brain suddenly feels like it’s running on low battery, Ahmed points to research showing women tend to have lower creatine levels in the frontal lobe, the part of the brain that handles mood, memory and cognition, with that gap becoming more pronounced as oestrogen fluctuates, “suggesting that creatine production does not stay steady in women as it does in men, and that can be related to hormones”. For something with this much research behind it, creatine is surprisingly easy to overthink. Creatine monohydrate is the one with decades of research behind it, and despite the newer formats (HCl, buffered, micronised), none of them have meaningfully outperformed it. Terry Tateossian, menopause lifestyle medicine coach and founder of Thor, advises her clients, “Take three to five grams a day, every day, of a quality monohydrate, with a meal, for the rest of your life. Don’t load. Don’t cycle. Don’t overthink it.” For women already juggling a supplement routine, Ancient + Brave’s True Creatine+ is female-founded, B Corp certified, and blends magnesium, taurine and vitamin D into the mix, which means one less thing to add to the shelf. While brands like Thorne and Momentous, both NSF-Certified for Sport and independently tested for purity, are the ones to reach for if clinical credibility is the priority. The research on creatine and women is still catching up. There’s more to learn about hormonal variability, about the different life stages, about everything the early studies missed by defaulting to male subjects. But the direction it’s heading is pretty consistent. “Creatine doesn’t build muscle. What it does is increase the capacity to do the work that builds the muscle,” says Tateossian. Turns out that capacity was always there.
