UF Study Links Glucosamine to 25% Higher Dementia Risks in 50,000 Patients

Summary
More than 50,000 UF Health records showed glucosamine users with mild cognitive impairment were 25% more likely to progress to dementia, while dementia patients taking it faced a 25% higher risk of death.
About 8% of both groups reported using the joint supplement, and researchers said the risk signal appeared strongest after dementia was already established.
Nature Metabolism published the study, which used AI to analyze anonymized records from 2012 to 2024 and adjusted for age, sex and other known risk factors.
University of Florida scientists said glucosamine can cross the blood-brain barrier and may worsen an already overactive protein sugar-tagging process seen in Alzheimer’s brains.
The team stressed the findings show association, not causation, and said only people with dementia or MCI—not healthy adults—should discuss alternatives with their doctors pending clinical trials.

Overview
Recent University of Florida research highlights a concerning link between glucosamine supplements and faster progression of dementia in people already diagnosed with Alzheimer’s and related conditions. The study suggests that glucosamine may worsen cognitive decline, prompting experts to recommend that patients and clinicians reconsider its use in these cases. The proposed mechanism involves glucosamine fueling abnormal sugar buildup in the brain, which could disrupt normal brain function. These findings underscore the importance of reviewing supplement regimens for dementia patients and considering alternative treatments, as commonly used supplements may have unexpected negative effects on vulnerable populations.
