Increased Blood Sugar

Glucosamine may slightly increase blood sugar levels, especially in individuals with diabetes. Monitoring blood glucose is recommended.

Glucosamine, a common supplement, has been observed in some instances to elevate blood glucose levels. This effect is particularly notable in individuals with pre-existing diabetes or those with impaired glucose tolerance. While the increase is often modest, it can potentially lead to hyperglycemia, characterized by symptoms such as increased thirst, frequent urination, blurred vision, and fatigue. Careful monitoring of blood sugar levels is advised to detect and manage any significant changes. The precise mechanism by which glucosamine affects blood sugar is not fully understood, but it may involve interference with insulin signaling or glucose metabolism.
