Does Long-Term Glucosamine Use Affect Blood Sugar Levels?

The issue of ammonium glucose?

Director Shi, I am currently taking glucosamine due to some joint issues and need to use it long-term to improve my condition.
However, my blood sugar is slightly elevated, with a pre-meal reading of 101.
Could you please advise if long-term use of glucosamine could raise my blood sugar levels and what issues I should be aware of? Thank you for taking the time to respond; I greatly appreciate it.

Hello! Glucosamine is an amino derivative of glucose and is a component of many complex polysaccharides.
It is found throughout cartilage and connective tissues and is one of the essential nutrients for the formation of chondrocytes.
Glucosamine supplements are derived from chitin, a substance found in the shells of shrimp, lobsters, and crabs.
In the body, glucosamine is broken down into amino acids and can also be converted into galactose and chondroitin.
However, due to the minimal caloric contribution from its content, its impact on blood sugar levels is negligible, so you can rest assured in this regard.
If you have high blood pressure, however, you should pay attention to the sodium content in the glucosamine you are taking.
Sincerely, Dietitian Shih Kuei-Mei, Director of the Nutrition Department, Taoyuan Hospital, Ministry of Health and Welfare.

More Info

Long-term use of glucosamine, a supplement commonly used for joint health, has raised questions regarding its potential impact on blood sugar levels, particularly for individuals who may already have elevated blood glucose. Glucosamine is an amino sugar that is a natural component of cartilage and is often derived from shellfish or produced synthetically. It is primarily used to alleviate symptoms of osteoarthritis and improve joint function.

Research indicates that glucosamine does not significantly affect blood glucose levels in most individuals. The metabolic pathway of glucosamine is distinct from glucose metabolism, and while glucosamine can be converted into glucose in the body, the amount produced is typically minimal and unlikely to cause a significant increase in blood sugar levels. Therefore, for most people, including those with slightly elevated blood sugar levels, glucosamine supplementation is generally considered safe and should not lead to a substantial rise in blood glucose.

However, it is essential to consider individual health conditions and other factors that may influence blood sugar levels. For instance, if you are taking other medications or supplements that affect glucose metabolism, or if you have underlying conditions such as insulin resistance or diabetes, it is crucial to monitor your blood sugar levels more closely. Additionally, lifestyle factors such as diet, physical activity, and weight management play a significant role in blood sugar control and should be addressed alongside any supplementation.

When taking glucosamine, it is also important to be aware of potential side effects. Some individuals may experience gastrointestinal discomfort, including bloating, diarrhea, or nausea. Allergic reactions, although rare, can occur, particularly in those who are allergic to shellfish. If you notice any adverse effects or changes in your health status, it is advisable to consult with your healthcare provider.

In your case, with a fasting blood sugar level of around 101 mg/dL, it is prudent to maintain regular monitoring of your blood glucose levels. This can help you and your healthcare provider determine if any adjustments to your diet, exercise regimen, or medication are necessary. Keeping a food diary and noting your blood sugar readings can provide valuable insights into how your body responds to glucosamine and other dietary factors.

In summary, long-term glucosamine use is unlikely to significantly elevate blood sugar levels for most individuals. However, it is essential to remain vigilant about your overall health, monitor your blood glucose levels, and maintain open communication with your healthcare provider regarding any concerns or changes in your condition. By doing so, you can effectively manage your joint health while keeping your blood sugar levels in check.
