Calcium Supplements Found Safe for Brain Health in Older Women

New research from Edith Cowan University, Curtin University, and the University of Western Australia has found no link between calcium supplementation and dementia risk in older women. Drawing on data from 1,460 participants who received either calcium or a placebo over five years, researchers observed no long-term increase in dementia cases. The findings counter earlier concerns that calcium might harm cognitive health. According to study authors, the results remained consistent after accounting for dietary habits, genetics, and lifestyle factors. This randomized, placebo-controlled trial offers stronger evidence than previous observational studies, with a 14.5-year follow-up enhancing reliability. About one in five women over 70 live with osteoporosis, and calcium is commonly prescribed to prevent fractures. The study provides reassurance for patients and clinicians that long-term calcium supplementation supports bone health without raising dementia risk, though further research is needed across other populations.
