Study Links Glucosamine Supplement to Accelerated Alzheimer's Progression

A new study published in Nature Metabolism suggests a link between glucosamine use and a 25% higher likelihood of mild cognitive impairment advancing to dementia. Laboratory experiments indicate the popular joint supplement may intensify an abnormal sugar-tagging process in the Alzheimer's brain. Researchers emphasize these findings are preliminary and call for clinical trials to confirm a causal relationship, highlighting metabolism's potential role in neurodegeneration.
