Popular Joint Pain Supplement May Accelerate Dementia Progression

University of Florida neuroscientists have discovered an association between glucosamine, a widely-used over-the-counter supplement for joint pain, and increased risk of progression from mild cognitive impairment to Alzheimer's disease. The finding comes from a large retrospective analysis of patient records combined with advanced brain imaging studies and research on Alzheimer's disease models. Glucosamine is commonly taken by millions of people seeking relief from arthritis and joint discomfort, making this discovery particularly significant for public health. The research suggests that those taking glucosamine who have cognitive concerns should consult their healthcare providers about potential risks and alternatives. While more prospective studies are needed to confirm causation, this finding warrants careful consideration when deciding on long-term supplement use.
