Supplement Linked to Faster Alzheimer’s Progression

Research from the University of Florida suggests that a common supplement, glucosamine, may speed up Alzheimer’s disease progression. According to a study published in Nature Metabolism, individuals showing signs of mild cognitive impairment were 25% more likely to advance to dementia when using glucosamine as opposed to those who did not.

Additionally, the study found a 25% increased risk of death among Alzheimer’s patients taking glucosamine.

A Neuropsychologist’s Perspective

Dr. Jessica McCarthy, a neuropsychologist from New Jersey, provided her insights on these findings. She highlighted that Alzheimer’s might be influenced by metabolic dysfunction and inflammation, beyond just amyloid plaques and tau proteins. Glucosamine’s ability to cross the blood-brain barrier could exacerbate metabolic issues in those with cognitive impairment or Alzheimer’s.

McCarthy expressed concerns about people resorting to supplements without understanding their impact. She emphasized the potential dangers of glucosamine interacting with existing health conditions.

Understanding Glucosamine

Glucosamine is a popular over-the-counter supplement in the U.S., often used for joint pain, particularly among older adults. Given the demographic, researchers aimed to see if glucosamine contributes to neurological decline.

The study utilized artificial intelligence to review patient records between 2012 and 2024. Of the patients studied, approximately 8% reported using glucosamine. Data adjustments for factors like age and demographics indicated that glucosamine users had higher odds of progressing to dementia.

Further research suggested glucosamine might interfere with brain metabolic processes related to Alzheimer’s. However, the increased mortality risk was only observed in patients already diagnosed with dementia.

Recommendations for Glucosamine Users

The researchers caution that these findings are observational, and clinical trials are necessary for confirmation. However, metabolic dysfunction remains a significant concern in neurodegenerative diseases.

McCarthy recommends focusing on modifiable behaviors to enhance brain health. She advises at least 45 minutes of moderate exercise three to four times a week, sufficient sleep, a Mediterranean diet, and adherence to prescribed medications.

Consulting with a medical professional before using supplements is crucial. Maintaining a healthy lifestyle can help manage inflammation and support a healthy brain.
