Creatine and menopause: muscle, bone, mood, and brain fog

Menopause speeds up the loss of muscle and bone. Creatine has been tested in women going through this change. With resistance training, it adds small gains in muscle and strength. Its effect on bone density is mixed and mostly null. Research on mood and brain fog is new and based on small studies. Creatine works alongside resistance training. It does not replace training or menopause care.

What changes in your body during menopause?

Menopause is the point when periods stop for good. The years before it, when hormones start to change and periods become irregular, are called perimenopause. Falling estrogen during this time affects muscle, bone, and the brain.

• Muscle. A large U.S. study of women followed through menopause (SWAN) found that lean mass starts to decline at the start of the menopause transition. At the same time, the rate of fat gain doubles. Both changes continue until about 2 years after the last period.
• Bone. In the same study, bone loss began about 1 year before the last period. Over 10 years, women lost about 10.6% of their spine bone density. About 7.4% of that loss happened in the 3 years around the last period.
• Mood and thinking. Many women report poor concentration, memory lapses, and mood changes. One small 2026 brain scan study of 12 perimenopausal women found lower brain creatine levels than in younger adults. Lower levels in some brain areas were linked to more trouble concentrating.

Creatine is involved in how muscle and brain cells supply energy. That is why researchers have started to test it in women at this stage of life. A 2021 review of creatine across a woman's lifespan suggested that hormone changes may affect how the body handles creatine, and that supplements may be most relevant during and after menopause. That is a research idea. The trial results below show how far it holds up.

Does creatine help muscle and strength after menopause?

Yes, a little, when it is combined with resistance training. A 2026 meta-analysis pooled 7 randomized trials with 608 postmenopausal women, average age about 62. Compared with placebo, creatine led to about 0.37 kg more lean mass and about 7.5 kg more on the leg press. The benefits appeared in trials that combined at least 5 g per day with resistance training. Trials that used 3 g per day or less without training found no measurable effect.

The single trials show the same pattern:

• In a 12-month trial in 47 postmenopausal women who did resistance training 3 days per week, the creatine group improved bench press strength (relative to body weight) by 64%, compared with 34% in the placebo group.
• In a 2-year trial in 237 postmenopausal women who did resistance training and walking, creatine did not improve bench press or hack squat strength more than placebo. Women taking creatine did get faster on an 80 m walking test. Among those who completed the study as planned, lean mass rose more with creatine.
• In a 2-year trial in 200 older women with low bone mass who took 3 g per day without a training program, creatine did not change lean mass or physical function.

The message is consistent. Resistance training drives most of the gain, and creatine adds a small extra effect on top. Taking creatine without training is unlikely to help much. See creatine without working out for more on this.

Does creatine protect bone during menopause?

This is where the results are most mixed. The trials so far:

• 12 months, 2015. In 33 postmenopausal women who completed a resistance training program, bone density at the femoral neck (top of the thigh bone) fell by 1.2% with creatine and by 3.9% with placebo. Spine bone density did not differ between the groups.
• 2 years, 2023. In the largest trial, 237 postmenopausal women did resistance training and walking. Creatine had no effect on bone mineral density at the hip or spine. It did help maintain two measures of hip bone shape that are linked to bone strength.
• 2 years, 2020. In 200 women with low bone mass who took 3 g per day without training, creatine did not change bone density, bone markers, falls, or fractures.
• Meta-analysis, 2026. Across the trials in postmenopausal women, bone density did not change overall.

The honest summary is that creatine has not been shown to raise or protect bone density in menopause. It may help bone in an indirect way, through stronger muscles and better training. It is not a treatment for osteoporosis. If you have low bone density, follow the plan from your doctor, which may include medicines, calcium and vitamin D, and exercise.

Can creatine help with menopause brain fog and mood?

The evidence here is early. In a 2026 trial, 36 perimenopausal and postmenopausal women took one of three creatine products or a placebo for 8 weeks. The trial used creatine hydrochloride, a different form from the creatine monohydrate used in most research, at low doses. The group taking 1.5 g per day of creatine hydrochloride improved reaction time more than the placebo group, and their creatine levels in the front of the brain went up. There was a possible reduction in mood swings, but it was not statistically significant.

This is one small, short trial. It does not show that creatine treats brain fog, low mood, or depression. Reviews of creatine in women describe positive early findings on mood and thinking, and they also say that data in perimenopause are still limited. Our guide on creatine and brain health covers the wider brain research.

If you have ongoing low mood, anxiety, or memory problems, talk with your doctor. These symptoms can have many causes, and there are proven treatments.

Is the research different for perimenopause and postmenopause?

Yes. Almost all of the muscle and bone trials were done in postmenopausal women, often several years after their last period. A 2025 review of creatine in women's health noted that data on perimenopausal women remain limited. So most of what is said about creatine in perimenopause is based on studies in older women or on research ideas about hormones and creatine.

If you are in perimenopause, the safest reading is this: creatine is well studied in adults in general, and resistance training is clearly useful at this stage. Whether creatine gives women in perimenopause any special benefit has not yet been tested in enough trials. For a wider view of creatine in women, including the menstrual cycle, see creatine for women. For adults over 50 in general, see creatine over 50.

Is creatine safe during menopause, and can you take it with HRT?

In the 2026 meta-analysis of postmenopausal women, side effects were mild and similar to placebo, and kidney markers did not change. The 2-year trial using 3 g per day also found no changes in health-related lab tests.

Creatine is not a hormone. It does not replace hormone replacement therapy (HRT) or other menopause care. We found no trials that tested creatine together with HRT. If you use HRT or other medicines, mention creatine to your doctor or pharmacist.

Talk with your doctor before starting creatine if you have kidney disease, diabetes, or high blood pressure, or if you take medicines that affect the kidneys. Creatine can also raise creatinine, a blood marker used to estimate kidney function, without harming the kidneys. Tell your doctor you take it before blood tests. Our guides on creatine and kidneys and the creatinine blood test explain this.

How do women in menopause use creatine in the studies?

The trials that found benefits had a few things in common:

• Resistance training 2 to 3 times per week. In the main trials, women trained 3 days per week. Machines, free weights, and bands all count.
• Months, not weeks. The trials lasted from 12 weeks to 2 years. Small changes in muscle build up over time.
• Daily use. Creatine works by slowly filling the muscle's reserves, so the studies gave it every day.
• Creatine monohydrate. This is the form used in nearly all muscle and bone trials.

The trials used different amounts, including fixed daily amounts and amounts based on body weight. For the usual amounts and how they were set, see how much creatine per day. Enough protein and a plan you can keep up matter as much as the supplement.
