Creatine for Women: Does It Work?
Short answer: yes. The research on creatine for women is as strong as for men.
Creatine is a naturally occurring compound in muscle and brain tissue. It replenishes ATP (your cells energy currency). Every human benefits from this regardless of sex.
What the Research Shows for Women
Strength and muscle: Smith-Ryan et al. 2021 (Nutrients): creatine in women produced significant gains in lean mass and strength comparable to men on a relative basis
Brain performance: Rae et al. 2003 (Proceedings of Royal Society): 5g/day creatine for 6 weeks improved working memory and processing speed
Menstrual cycle support: Preliminary data suggests creatine may help offset the cognitive dip during the luteal phase
Bone density: Chilibeck et al. 2017: creatine combined with resistance training improved bone mineral density in postmenopausal women
Does Creatine Cause Bloating or Weight Gain in Women?
There is initial water retention in muscle cells (not under the skin). This typically adds 1-2 lbs in the first week. This is intramuscular water and most women find it normalizes as body composition changes.

Does Creatine Cause Hair Loss?
One study (van der Merwe et al. 2009) found creatine increased DHT in rugby players. However: this study has not been replicated, no direct hair loss was observed, and current consensus is that creatine is unlikely to cause hair loss in women.
Bottom Line
Creatine monohydrate at 3-5g per day is one of the best evidence-based supplements for women doing resistance training, caring about brain performance, or in perimenopause.
