Over in the Pets Blog, I’ve been talking quite a bit about glucosamine and chondroitin for pets with joint issues like arthritis and hip dysplasia. But glucosamine and chondroitin can be helpful for humans with joint issues, too!
Glucosamine and chondroitin are part of normal, healthy cartilage — the stuff that acts as a cushion between the bones in a joint. They are available separately or together in tablet, powder, and liquid form.
- Glucosamine naturally occurs in the shells of shellfish and is also available in synthetic forms.
- Chondroitin occurs naturally in some animal cartilage and can also be synthesized in a lab.
For people with osteoarthritis, glucosamine and chondroitin can help relieve joint pain. Studies don’t always agree on the pain relief aspect of the supplements, but research does indicate that glucosamine and chondroitin can help restore cartilage. On the pain relief side, some studies show that both supplements are useful; others show that only one or the other can help.
These supplements seem to have few side effects. A few precautions when taking glucosamine and chondroitin:
- People with osteoarthritis and diabetes should talk to a doctor before taking glucosamine — glucosamine may influence blood sugar levels.
- People with shellfish allergies should not take glucosamine that is made from shellfish shells!
- The U.S. Food and Drug Administration does not regulate dietary supplements. They can be sold with limited (or even none) research on effectiveness. Manufacture is not standardized — so different brands may work very differently.
- Talk to your doctor before using any supplement — it may not combine well with other medications you are using.
- Don’t stop or start any medications without talking to your doctor first. You may be eager to replace conventional medications with a natural alternative, but your health care professional should be aware of any changes you make.
