The short version: Dr. Stacy Sims recommends 3–5 g of creatine monohydrate daily for women. No loading phase. No cycling. No specific timing. Look for Creapure-branded monohydrate with third-party testing, and choose powder over capsules or gummies. If you are uncertain, start at 1–2 g and work up. That is the entire protocol, and its simplicity is the point.
Sims is an exercise physiologist and nutrition scientist known for research and advocacy around female-specific training and fueling — she is the author of ROAR and Next Level, and the phrase most associated with her work is “women are not small men.” Creatine is one of very few supplements she recommends broadly.
Why she recommends it for women specifically
Her case rests on three points that stack.
Women start with less. Sims cites research indicating women have substantially lower baseline intramuscular creatine stores than men — a figure often quoted as 70–80% lower. Worth understanding what that means: it derives from comparisons of total creatine stores and dietary intake, not a claim that female muscle is nearly empty. The directional point is what matters. Lower baseline means more headroom.
Women eat less of it. Creatine comes almost entirely from red meat and seafood. Women consume less of both on average and are more likely to eat plant-based, which compounds the baseline difference. The case is strongest of all for women who are vegetarian or vegan.
Supplementation can raise stores by roughly 20%. Combined with the lower starting point, this is the basis for her argument that women may see equal or greater relative benefit than men — a position supported by some of the literature, though the systematic review of performance studies in active women found the female-specific trial evidence too heterogeneous to confirm it.
She also emphasizes that the framing has shifted. For women in perimenopause and beyond, she describes creatine as moving from a performance supplement to a foundational support nutrient — for muscle, bone, recovery, and training capacity as estrogen declines.
The protocol
Dose: 3–5 grams per day
That is it. She is explicit that there is no real need to exceed 3–5 g under normal circumstances, and that if you are uncertain or have a sensitive stomach, starting at 1–2 g and building up is fine.
She draws a pointed contrast with bodybuilding convention — where 5 g taken four times a day is common — noting that for health and for women, the dose is 3–5 g once daily. The bodybuilding protocols were designed around different goals, different body sizes, and different tolerance for side effects.
No loading phase
This is her clearest departure from conventional advice. The traditional protocol front-loads roughly 20 g/day for five to seven days to saturate muscle stores quickly.
Her position: 3–5 g/day fully saturates muscle creatine within about three to four weeks, without the GI distress loading commonly causes. Loading gets you to the same place faster with more discomfort. Unless you have a competition in ten days, the slower route is better.
Timing doesn’t matter
Pre-workout, post-workout, morning, evening — she describes timing as not critical. What matters is consistency, so pick a time you will actually remember. Creatine works by keeping muscle stores saturated, which is a function of daily intake rather than of hitting a metabolic window.
No cycling
Nothing in her guidance supports cycling on and off. Consistency maintains saturation; stopping lets stores drift back down.
Form: monohydrate, ideally Creapure
She recommends creatine monohydrate as the most researched, most effective, and most cost-efficient form. Specifically, she recommends looking for Creapure®, a pharmaceutical-grade monohydrate produced in Germany using a water-based process, which she notes tends to produce fewer GI side effects than cheaper acid-washed alternatives.
Two practical notes: Creapure is an ingredient brand rather than a consumer product — you cannot buy it directly, so you look for it on the label of finished products. And regardless of brand, she recommends independent third-party testing by organizations such as NSF or Informed Sport.
Format: powder over capsules and gummies
- Powder — most researched, most cost-efficient, most dose-accurate. Tasteless and mixes into water, smoothies, oatmeal, yogurt, or a recovery drink.
- Capsules — convenient, but reaching an effective dose often means swallowing a lot of pills.
- Gummies — she advises against them. Added sugars, poor dosing accuracy, and the heat and moisture involved in gummy manufacturing can degrade creatine into creatinine, meaning you may not be getting what the label claims.
One practical detail worth knowing: creatine is stable mixed into most foods and drinks, but once mixed into fluid, take it within about four to five hours rather than letting it sit overnight.
Her positions on the common concerns
Her answers here align closely with the broader safety literature:
Weight gain: Some women see roughly a pound on the scale from increased water inside muscle cells. Not fat, and usually temporary.
Bulk: No. Muscle size is driven by training, nutrition, and hormones. Creatine supports strength and power; it does not override your physiology.
Bloating: Uncommon at 3–5 g/day. When it happens it is usually large loading doses or low-quality product.
Hair loss: No evidence in women. The claim traces to one small study in men that did not measure hair loss and has not been replicated.
Kidneys: Decades of research show no evidence of harm in healthy people at recommended doses. Elevated blood creatinine reflects intake, not damage. Pre-existing kidney disease requires medical supervision.
Hydration: Creatine increases water inside muscle, not dehydration. No evidence of increased cramping. No need for “extra” water beyond what your training and environment already demand.
Coffee: Fine together. If you have a sensitive stomach, taking it with coffee on an empty stomach may cause mild discomfort — take it with food instead.
Teens: She considers it appropriate with supervised training and adequate nutrition, suggesting a conservative 3 g/day start and involvement from a healthcare provider or sports dietitian.
Perimenopause and menopause: Yes — she considers this a period where creatine becomes more valuable, not less.
Pregnancy: She is supportive but directs women to talk with their provider first, and suggests being comfortable with creatine pre-pregnancy. Note that the research evidence in pregnancy remains limited.
Endometriosis: This is where she is most cautious. She points to 2024–2025 research suggesting caution with active endometriosis, while noting the work is largely lab and animal models with no clear human data yet.
How her guidance compares to the research
Broadly, it is well aligned — with one honest tension worth naming.
Where it aligns: The 3–5 g/day recommendation matches the dose used in the mood research and sits within standard practice. Her no-loading position is supported by saturation kinetics. Her emphasis on monohydrate over novel forms matches the 2025 narrative review’s assessment. Her safety positions track the ISSN position stand closely.
Where there’s tension: The 12-month bone trial in postmenopausal women used roughly 10 g/day — about double her recommendation. Whether 5 g produces equivalent bone effects has not been established. Similarly, the cognition research used much larger doses, and brain uptake appears harder to achieve than muscle uptake. It is possible that 3–5 g is right for muscle and conservative for bone and brain. Nobody has run the study that would settle it.
That is not a criticism of her guidance. Recommending the dose with the best-established safety and tolerability profile, while the dose-response research is still incomplete, is a defensible call.
Frequently asked questions
How much creatine should a woman take daily? Sims recommends 3–5 g of creatine monohydrate per day, with 1–2 g as a starting point if you are uncertain or have a sensitive stomach.
Do women need to load creatine? No. 3–5 g/day saturates muscle stores in about three to four weeks without the GI discomfort loading can cause.
When should I take creatine? Whenever you will consistently remember. Timing is not critical; consistency is.
What is Creapure and do I need it? Creapure is a high-purity creatine monohydrate produced in Germany via a water-based process. Sims recommends looking for it on product labels. Any third-party-tested pure monohydrate is a reasonable choice.
How long before I notice anything? Muscle stores saturate in three to four weeks. Judge the effect over a training block of a few months, not a few days.
