While glucosamine has long been associated with knees and joints as well as pain relief, new research is looking into a much more surprising area: how this commonly used supplement affects the brain once inside it.
An experiment done at the University of Florida linked glucosamine usage with worsening dementia in patients suffering from mild cognitive impairment (MCI). In addition, the researchers have found evidence in mice and human brains showing changes in the cellular mechanism responsible for attaching sugar molecules to proteins.
