Summary

Story summary

A University of Florida study found Alzheimer’s patients taking glucosamine faced a 25% mortality risk over five years.
Researchers reviewed UF Health records of 24,000 dementia and 41,000 patients and linked glucosamine use to faster progression.
Mouse studies showed blocking glucosamine production improved symptoms, while feeding it worsened memory loss in mice.
Authors note the observational study cannot prove causation and will follow the 8% who stopped glucosamine for outcomes.
