New Study Raises Concerns About Glucosamine

Glucosamine, One of the Most Popular Joint Supplements, May Be Linked to Increased Risk of Alzheimer’s Disease and Death

Millions of people take glucosamine every year to support joint health and help manage osteoarthritis. However, emerging research suggests there may be reasons for caution.

A study conducted by researchers at the University of Florida found that glucosamine use was associated with a 25% higher risk of receiving an Alzheimer’s disease diagnosis among individuals with mild cognitive impairment. The study also reported a 25% higher risk of death within the study period among glucosamine users.

Researchers suggested that glucosamine may contribute to metabolic processes that could be harmful in individuals already at risk for Alzheimer’s disease.

One possible explanation involves a process known as “sugar tagging” (glycosylation), where sugar molecules attach to proteins or fats inside cells. This process is essential for normal cellular function. However, because glucosamine is a sugar-like molecule, researchers believe it may cross the blood-brain barrier and potentially interfere with normal metabolic pathways, leading to excessive sugar tagging and unwanted effects in the brain.

While glucosamine continues to be widely used and may benefit some individuals, these findings highlight the importance of discussing all supplements with your healthcare provider, especially if you have concerns about cognitive health or a family history of Alzheimer’s disease.

As always, more research is needed to fully understand the long-term effects of glucosamine supplementation.
