A widely used joint supplement called glucosamine may make Alzheimer's disease worse. Researchers found that people who took this supplement were more likely to develop dementia than those who didn't.

Alzheimer's is a serious brain disorder that affects millions of people worldwide. A recent study from the University of Florida discovered that taking glucosamine, a common joint pain relief supplement, may actually make Alzheimer's worse. The researchers analyzed health records and brain tissue to understand how glucosamine affects the brain.

Glucosamine is often taken by older adults to support joint health. However, this study found that people with mild cognitive impairment who took glucosamine were 25% more likely to develop dementia than those who didn't take it. The researchers also discovered that glucosamine use was linked to a 25% increase in mortality risk among people already diagnosed with Alzheimer's.

The study suggests that altered metabolism plays an important role in Alzheimer's progression. This means that addressing metabolic defects could be an important part of treating the disease.
