About Glucosamine
Glucosamine sulfate is a popular dietary supplement used primarily for managing osteoarthritis symptoms. It is sourced from shellfish or produced synthetically. While it may provide pain relief and improve joint function for some individuals, its long-term effects on cartilage are still being researched. Common side effects are generally mild, but shellfish allergies pose a significant risk for some. Individuals with diabetes or insulin resistance should exercise caution due to potential effects on blood sugar control.
