Sleep can become surprisingly complicated around perimenopause and menopause.
Hot flushes, night sweats, changing sleep patterns, stress and hormonal fluctuations can all make getting a good night's sleep more difficult.
And when sleep suffers, everything can feel harder – exercise, concentration, mood and recovery included.
So where does creatine fit in?
The research is still early, but there are some interesting connections between creatine, energy metabolism and sleep deprivation.
Creatine and cellular energy
Creatine helps regenerate ATP, providing rapidly available energy to cells.
This isn't limited to muscle. Creatine and phosphocreatine also play an important role in the brain.
Researchers have therefore investigated whether increasing creatine availability might help the brain cope with energetic stress.
Sleep deprivation is one such stress.
What happens when we don't sleep?
Sleep deprivation can affect reaction time, attention, memory and mood.
One study found that seven days of creatine supplementation at 20 g/day reduced some of the performance and mood effects associated with 24 hours of sleep deprivation.
McMorris et al. research
But this is an important caveat: the study investigated sleep deprivation, not women with menopause-related insomnia.
So it doesn't demonstrate that creatine improves sleep.
Has creatine been shown to improve sleep?
Not convincingly.
There is some emerging research in women suggesting that creatine may influence sleep-related outcomes under certain conditions.
A six-week study in young women undertaking resistance training found increased total sleep duration on training days with creatine compared with placebo, but it did not demonstrate an improvement in overall chronic sleep quality.
Aguiar Bonfim Cruz et al. research
These participants were not menopausal.
So, once again, the finding is interesting rather than definitive for menopause.
Recovery may be a more useful way to think about it
If you're strength training, recovery is essential.
Creatine can increase muscle creatine stores and support the energy systems involved in high-intensity muscular activity.
That may help explain why creatine is consistently studied alongside resistance exercise.
A 2025 review of creatine in women's health found that the most consistent benefits in postmenopausal women occur when creatine is paired with resistance training.
Menopause, sleep and exercise
There is another reason to connect these subjects.
Exercise can support overall health during menopause, while poor sleep can make exercise feel much harder.
Rather than looking for a single supplement to solve sleep, it may be more useful to build a recovery routine around:
- Consistent sleep and wake times.
- A bedroom environment that is comfortable and cool.
- Regular physical activity.
- Resistance training.
- Adequate nutrition and hydration.
- Stress-management strategies.
- Medical support for persistent menopause symptoms where needed.
Creatine can potentially sit within that routine.
What about taking creatine at night
There isn't strong evidence that creatine needs to be taken at a particular time of day for menopause or sleep.
Consistency is more important than timing.
Health & Her Creatine+ recommends three capsules daily, preferably with a meal.
The bottom line
Creatine isn't a sleeping tablet, and there isn't currently enough evidence to recommend it as a treatment for menopause-related insomnia.
What is interesting is the relationship between creatine, cellular energy, exercise and recovery.
For women who are already strength training, creatine may be a useful part of a broader healthy-ageing routine.
But if sleep is consistently poor during menopause, the first step should be identifying and addressing the reason for the disruption rather than expecting a supplement to solve it.
