Hello, Doctor.
I would like to ask about my mother, who has mild diabetes and has been on medication for long-term control.
However, she is experiencing knee joint degeneration.
A friend suggested that she take liquid glucosamine supplements (such as Nuliv or Haoguli).
I would like to know if it is safe for her to consume these.
Thank you, Doctor.

Hello: In response to your questions.

1.
Glucosamine is converted in the body into glycoproteins and glycosaminoglycans; it is believed to enhance the synthesis of proteoglycans within cartilage, thereby improving the progression of osteoarthritis.
Adverse reactions are limited to mild upper abdominal discomfort, nausea, heartburn, rashes, headaches, and drowsiness.
2.
Due to structural and metabolic considerations, there are concerns regarding the impact of glucosamine on blood glucose control in diabetes.
Some studies suggest that glucosamine does not affect blood glucose control, while others indicate it may influence insulin sensitivity.
There is still some controversy in the medical community.
However, it is not completely dismissed.
It is advisable to regularly monitor blood glucose levels and maintain usual blood glucose management activities if using glucosamine.
Additionally, be sure to check the labels of various dietary supplements for any other ingredients that may require attention.
3.
It is recommended to consult your physician for an evaluation.

More Info

Glucosamine supplements, particularly in the form of glucosamine sulfate or glucosamine hydrochloride, have gained popularity as a potential aid for individuals suffering from knee joint degeneration, often associated with osteoarthritis. These supplements are derived from shellfish or can be synthesized in laboratories, and they are primarily used to support joint health by promoting the synthesis of cartilage and synovial fluid, which are crucial for joint lubrication and cushioning.

Composition and Mechanism of Action
Glucosamine is an amino sugar that plays a vital role in the formation and repair of cartilage. It is often combined with chondroitin sulfate, another compound that is believed to enhance the effects of glucosamine by providing additional support to cartilage and inhibiting enzymes that break down cartilage. Together, these compounds are thought to help reduce pain and improve joint function in individuals with osteoarthritis.

Efficacy
Research on the efficacy of glucosamine supplements has yielded mixed results. Some studies suggest that glucosamine can provide moderate relief from knee pain associated with osteoarthritis, while others indicate that the benefits may be minimal or not significantly different from a placebo. The variability in results may be due to differences in study design, the specific formulations of glucosamine used, and the populations studied.

For individuals with knee joint degeneration, particularly those with osteoarthritis, glucosamine may help alleviate pain and improve mobility. However, it is essential to note that the response to glucosamine can vary from person to person. Some individuals report significant improvement, while others may not experience any benefits.

Safety and Considerations
In general, glucosamine supplements are considered safe for most people when taken at recommended doses. Common side effects may include gastrointestinal discomfort, such as nausea, diarrhea, or constipation. There is also a potential for allergic reactions, particularly in individuals who are allergic to shellfish, as some glucosamine products are derived from shellfish sources.

For your mother, who has mild diabetes and is on medication, it is crucial to consult with her healthcare provider before starting any new supplement, including glucosamine. While glucosamine itself does not have a direct impact on blood sugar levels, individual responses can vary, and it is essential to ensure that it does not interfere with her diabetes management or medications.

Recommendations
If your mother is considering glucosamine supplements, here are some recommendations:
1. Consult a Healthcare Provider: Before starting glucosamine, it is vital to discuss it with her doctor or a registered dietitian, especially considering her diabetes and any medications she may be taking.

2. Choose Quality Products: If approved by her healthcare provider, opt for reputable brands that have undergone third-party testing for quality and purity. Products like "NutraBio" or "Schiff" are often recommended for their quality.

3. Monitor for Side Effects: If she starts taking glucosamine, monitor her for any side effects or changes in her blood sugar levels. Regular follow-ups with her healthcare provider can help manage any potential issues.

4. Combine with Other Treatments: Glucosamine should not be viewed as a standalone treatment. It can be used in conjunction with other therapies, such as physical therapy, weight management, and pain relief medications, to provide a more comprehensive approach to managing knee joint degeneration.

5. Lifestyle Modifications: Encourage your mother to engage in low-impact exercises, maintain a healthy weight, and follow a balanced diet to support joint health and overall well-being.

In conclusion, glucosamine supplements may offer some benefits for knee joint degeneration, but individual responses can vary. It is essential to approach supplementation cautiously, especially in the context of existing health conditions like diabetes. Always prioritize professional medical advice to ensure safety and efficacy.
