Consumers currently using glucosamine supplements for joint pain face a difficult choice: continue use with potential cognitive risks or discontinue and seek alternative treatments. This may shift spending toward alternative joint therapies (prescription medications, physical therapy, other supplements) and increase healthcare costs for Alzheimer's-related care.
