Glucosamine, a popular joint supplement, linked to faster Alzheimer’s progression

Automatically curated summary from ScienceDaily — Mind & Brain.

According to a report by ScienceDaily citing a large health-record analysis, the use of glucosamine—a popular joint supplement—was associated with a 25% higher likelihood of mild cognitive impairment progressing to dementia. Complementary lab experiments suggest glucosamine might exacerbate an abnormal sugar-tagging process within the Alzheimer's brain. However, researchers emphasize that these findings rely on observational data, noting that dedicated clinical trials are still needed to establish whether glucosamine actually causes harm.

Context and limitations

The reported link relies on an observational health-record analysis and laboratory experiments; clinical trials are required to prove whether glucosamine directly causes harm or drives dementia progression.
