Creatine for women: what does the evidence show?
Creatine is a dietary supplement that has been studied far less in women than in men. Reviews find it appears to improve strength and exercise performance in premenopausal women, and may help muscle and bone in postmenopausal women alongside resistance training. Early weight gain is mostly water. Its safety in pregnancy has not been studied in humans.
Is creatine regulated as a supplement or a drug?
Creatine is sold as a dietary supplement. FDA does not approve dietary supplements for safety or effectiveness before they are sold, so product quality and label accuracy depend on the maker and on any independent testing. FDA
Why does creatine research in women differ?
Because women have been studied much less, and start from a different baseline. A 2021 review of creatine across women’s lifespans called the evidence in females understudied and reported that females have 70 to 80% lower creatine stores in the body than males. Nutrients 2021
Does creatine help premenopausal women?
For strength and high-intensity exercise, it appears to. The 2021 review concluded that creatine among premenopausal females appears effective for improving strength and exercise performance. Nutrients 2021
NIH’s Office of Dietary Supplements notes creatine seems to have little value for endurance activities. NIH ODS
Does creatine help muscle and bone after menopause?
The evidence is mixed. The 2021 review says postmenopausal women may see benefits in muscle size and function, and favorable effects on bone when creatine is combined with resistance training. A two-year trial in 237 postmenopausal women found no effect on bone mineral density. Nutrients 2021
In that trial, creatine with resistance training and walking improved some measures of hip bone geometry and walking time, but did not improve bone density or maximal strength. Med Sci Sports Exerc 2023
Does creatine make women gain weight?
Some people gain a little weight at first, mostly water. NIH’s Office of Dietary Supplements says creatine usually causes some weight gain because it increases water retention. The 2021 review in women calls the fear of weight gain largely unfounded, and says rapid gain is more common in males. NIH ODS
The women’s health review describes short-term gain as water weight. Nutrients 2021
A 2021 review of common creatine questions concluded that supplementation may not lead to water retention. Common questions and misconceptions about creatine supplementation (J Int Soc Sports Nutr 2021)
Is creatine safe for the kidneys?
In healthy people, studies have not shown harm. The International Society of Sports Nutrition found short- and long-term creatine use safe and well tolerated in healthy individuals, and found no support in the literature that creatine promotes kidney dysfunction. ISSN position stand
Creatine can raise blood or urine creatinine, a common kidney test, without meaning kidney function has dropped, so tell your clinician you take it before lab work. Common questions and misconceptions about creatine supplementation (J Int Soc Sports Nutr 2021)
Rare reactions include muscle stiffness, cramps and stomach upset. NIH ODS
Is creatine safe during pregnancy?
That is unknown. The 2021 review of creatine in women found no human studies of creatine supplementation during pregnancy, so anyone pregnant, trying to conceive or breastfeeding should discuss it with a clinician first. Nutrients 2021
How can you choose a creatine product?
Look for a Supplement Facts panel that lists creatine on its own rather than inside a proprietary blend, which shows only the total weight of the blend and not the amount of each ingredient. 21 CFR 101.36
An independent testing seal can confirm what is in the product. NIH’s Office of Dietary Supplements notes such seals do not show that a product is safe or effective. NIH ODS

Creatine for women: questions, answered
Is creatine good for women over 50?
It may help muscle size and function, and possibly bone when combined with resistance training, but results are mixed: a two-year trial in postmenopausal women found no effect on bone density. Discuss it with a clinician if you have kidney disease or take medicines.
Will creatine make me bloated?
Some people retain a little water at first, which shows up as weight gain. Reviews in women describe that gain as water rather than fat, and some find little water retention overall.
Can I take creatine while pregnant?
No human studies have tested creatine supplementation in pregnancy, so its safety there is unknown. Talk to your clinician before taking it.
