Does Creatine Supplementation Improve Bone Health in Postmenopausal Women?
No. In this two-year randomized controlled trial, creatine supplementation combined with exercise did not improve bone mineral density in postmenopausal women. However, creatine did help maintain certain bone strength properties at the hip, improved walking speed, and increased lean tissue mass compared to placebo.
Bone loss is a major concern for women after menopause. As estrogen levels drop, bones gradually become thinner and weaker, raising the risk of fractures. Creatine is a supplement most people associate with weightlifting and muscle building, but researchers have wondered whether it could also help protect bones. This large, well-designed trial set out to answer that question by tracking 237 postmenopausal women over two full years.
Dr. Kumar’s Take
I think this study is valuable precisely because it gives us a nuanced answer rather than a simple yes or no. Creatine did not boost bone density, and that is the headline. But the improvements in bone bending strength and walking speed are worth paying attention to. For postmenopausal women, the ability to walk faster and maintain stronger bone structure at the hip could translate into fewer falls and fractures in the real world. I would not recommend creatine solely for bone health based on this trial, but it adds to the growing evidence that creatine may offer benefits beyond just building muscle. The combination of resistance training and walking was the real backbone of this program, and that is something every postmenopausal woman should consider regardless of supplementation.
Study Snapshot
Researchers enrolled 237 postmenopausal women with an average age of 59 years and randomly assigned them to either a creatine group or a placebo group. The creatine group took 0.14 grams per kilogram of body weight per day throughout the study. Both groups followed the same exercise program, which included resistance training three days per week and walking six days per week, for two years. The primary outcome the researchers were looking for was changes in bone mineral density at the femoral neck, which is the narrow part of the hip bone and a common site for fractures. They also tracked bone density at the total hip and lumbar spine, along with bone geometric properties, walking speed, muscular strength, and lean tissue mass.
Results in Context
When it came to bone mineral density, creatine made no difference. Both groups experienced small, similar declines in bone density at the femoral neck, total hip, and lumbar spine over the two years. This means the supplement did not slow bone loss any more than exercise and a placebo did.
Where creatine did show a benefit was in bone geometry at the femoral neck. The creatine group maintained their section modulus, a measure that predicts how well a bone can resist bending forces, while the placebo group saw a significant decline. The creatine group also maintained a better buckling ratio, which reflects how well the outer layer of bone holds up under compression. Both of these differences were statistically significant.
Beyond the bones, creatine also improved walking speed. Women taking creatine shaved about 1.5 seconds off their 80-meter walking time over two years, while the placebo group stayed roughly the same. However, creatine did not give an extra edge in muscular strength. Both groups made impressive gains in bench press and hack squat over the two years, but those gains were similar whether they took creatine or placebo. Among women who completed the full study, creatine also led to a modest but significant increase in lean tissue mass compared to placebo.
Who Benefits Most
This study focused on postmenopausal women, and the benefits of creatine supplementation in this population appear to be subtle rather than dramatic. Women who are already committed to a regular exercise routine that includes resistance training may see the most value from adding creatine, particularly for maintaining bone structural strength and improving functional mobility. The lean tissue gains are also meaningful for this age group, since preserving muscle mass becomes increasingly important for balance, fall prevention, and overall independence as we age. Women who are looking for a supplement to directly increase bone density, however, should know that this trial did not show that benefit.
Practical Takeaways
- Creatine supplementation for two years did not increase bone mineral density, so it should not be relied on as a bone density treatment for postmenopausal women.
- The combination of resistance training three days per week and daily walking produced significant strength gains in both groups, reinforcing that consistent exercise is the foundation of bone and muscle health after menopause.
- If you are considering creatine, talk to your doctor first, especially if you have kidney concerns or take medications that affect kidney function.
- Focus on a well-rounded exercise program that includes weight-bearing and resistance exercises, as these showed clear benefits for all participants in this trial regardless of which supplement they received.

FAQs
Is creatine safe for postmenopausal women to take long-term?
In this two-year trial, creatine supplementation did not raise any notable safety concerns. The study used a dose of 0.14 grams per kilogram of body weight per day, which is within the range commonly used in research. That said, long-term safety data for creatine in older women is still limited compared to younger athletic populations. Women with pre-existing kidney conditions should be especially cautious and consult a doctor before starting creatine. It is always a good idea to have kidney function monitored through routine bloodwork if you plan to supplement for an extended period.
Why did creatine improve bone geometry but not bone mineral density?
Bone mineral density and bone geometry measure different aspects of bone health. Density tells you how much mineral is packed into a given area of bone, while geometric properties like section modulus and buckling ratio describe the structural shape and distribution of bone tissue. A bone can become stronger by redistributing its material in a more efficient pattern without necessarily adding more mineral overall. This study suggests that creatine may influence how bone tissue is arranged at the hip, improving its resistance to bending and compression forces, even though it did not increase the total amount of mineral present.
Should I take creatine if my main goal is preventing osteoporosis?
Based on this trial alone, creatine is not a proven strategy for preventing osteoporosis, since it did not improve bone mineral density over two years. However, the improvements in bone structural strength and lean tissue mass are relevant to fracture prevention, which is the real-world outcome most people care about. A comprehensive approach to osteoporosis prevention should prioritize regular weight-bearing exercise, adequate calcium and vitamin D intake, and medical evaluation of your fracture risk. Creatine could be considered as an add-on for its modest benefits to muscle mass and functional mobility, but it should not replace established prevention strategies.
Bottom Line
This large, two-year randomized controlled trial found that creatine supplementation did not improve bone mineral density in postmenopausal women who exercised regularly. However, creatine did help maintain bone bending strength at the hip, improved walking speed, and modestly increased lean tissue mass. The real star of the study was the exercise program itself, which produced significant strength gains for all participants. Creatine may offer modest additional benefits for bone structure and physical function, but it is not a substitute for consistent resistance training and weight-bearing activity.
