Calcium Supplements Do Not Increase Dementia risk, Landmark Study Finds
Perth, Australia – October 19, 2025 – Concerns about a potential link between calcium supplementation and increased dementia risk in older women have been largely alleviated by a extensive new study. Researchers from Edith Cowan University, Curtin University, and the University of Western Australia have discovered no evidence supporting this connection. The findings, published this week, offer crucial reassurance to both patients and healthcare professionals.
The Study’s Methodology and Scope
The examination meticulously analyzed data collected from a pre-existing five-year project involving 1,460 women. participants were randomly assigned to receive either calcium supplements or a placebo. Over an extended follow-up period of 14.5 years, researchers diligently monitored the participants for any signs of cognitive decline, specifically dementia.
“Our analysis reveals that calcium supplements, commonly prescribed for bone health, do not elevate the likelihood of developing dementia over the long term,” explained Negar Ghasemifard, a PhD Student at Edith Cowan University, who played a key role in the research.
Osteoporosis and Calcium: A Critical Connection
Approximately 20 percent of women over the age of 70 grapple with osteoporosis, a condition characterized by weakened bones. Calcium supplementation remains a cornerstone of preventative care and treatment, aimed at reducing the incidence of fractures. This new study reinforces the importance of maintaining bone health without undue concern for cognitive repercussions.
Previous studies had suggested a possible link between calcium and cognitive decline. Though, Dr. Marc Sim, a Senior Research Fellow at ECU, clarified that those studies were often observational. “Our research benefits from a robust methodology-a five-year double-blind, placebo-controlled randomized clinical trial-giving us more confidence in our findings.”
| Study component | Details |
|---|---|
| Participants | 1,460 Older Women |
| Supplement Duration | 5 Years |
| Follow-Up Period | 14.5 Years |
| Study Design | Double-Blind, Placebo-Controlled, Randomized |
Did You Know? According to the national Osteoporosis Foundation, a fracture occurs every 13 seconds in the United States.
Beyond the Initial Findings
even after accounting for factors like existing supplement use, dietary habits, lifestyle choices, and genetic predispositions, the study’s outcomes remained consistent. This level of adjustment strengthens the validity of the results.
“Previous research suggesting potential links between calcium supplement use and the risk for dementia was purely observational in nature,” Dr. Sim elaborated. “Our research, in comparison, consisted of a post-hoc analysis from a 5-year double-blind, placebo controlled randomized clinical trial.”
Future Research and Considerations
While the findings are encouraging, Professor Simon Laws, Director of ECU’s Center for Precision Health, stressed the need for continued investigation. “Whether these results apply to other demographics, such as men, or women initiating supplementation at a younger age, remains uncertain,” he stated.
Future clinical trials should focus on broader populations and incorporate rigorous assessments of brain health as primary outcome measures.Professor Blossom Stephan, Honorary Medical Advisor at Dementia Australia, lauded the research as “a very important finding that provides reassurance to clinicians and patients” regarding the long-term safety of calcium supplementation for bone health.
Pro Tip: Speak with your doctor before starting any new supplement regimen to ensure it’s appropriate for your individual health needs.
Understanding Dementia and Bone Health
Dementia is not a single disease but a collection of symptoms affecting cognitive abilities,including memory,thinking,and behavior. Maintaining overall health,including bone health,is crucial for a higher quality of life as individuals age.
Calcium plays a vital role in bone density, wich naturally declines with age, increasing the risk of fractures. Proper calcium intake, combined with weight-bearing exercise, can help mitigate this decline.

Frequently Asked Questions About Calcium and Dementia
- Dose calcium supplementation increase the risk of dementia? No, this study found no evidence of an increased risk of dementia associated with calcium supplementation in older women.
- What is the link between osteoporosis and dementia? While osteoporosis itself isn’t directly linked to dementia, both conditions are more common with age and can impact overall health and quality of life.
- Who should consider taking calcium supplements? Individuals at risk of osteoporosis, such as older women, should discuss calcium supplementation with their healthcare provider.
- Are there any side effects to taking calcium supplements? Some individuals may experience mild side effects like constipation. It’s critically important to follow recommended dosages.
- What other factors contribute to dementia risk? Age, genetics, lifestyle factors (diet, exercise, smoking), and cardiovascular health all play a role in dementia risk.
- Is Vitamin D important along with Calcium? Yes, Vitamin D helps the body absorb calcium. Many supplements combine both nutrients.
- What does this study mean for women already taking calcium supplements? It provides reassurance regarding the long-term safety of continuing calcium supplementation for bone health.
