A popular joint pain supplement may accelerate dementia

New research has found an association between taking glucosamine, a popular over-the-counter supplement used for joint pain, and a higher likelihood of progressing from mild cognitive impairment to Alzheimer's disease. The finding by University of Florida neuroscientists is based on a large retrospective analysis of patients' records as well as supporting data from advanced imaging technology used to scan human brain specimens and Alzheimer's disease mouse models.
