Unconvincing. Research has failed to give convincing evidence of benefit. Anecdotally, however, I have patients that swear by it. So, if it doesn't break the bank, a 2-3 month trial cannot hurt. But if no benefit, don't expect a longer duration to of any further benefit.
Maybe. There is some evidence that they may be helpful for treating osteoarthritis.
50/50. Glucosamine & chondroitin are supplements some believe help osteoarthritis pain; studies show mixed results; the american academy of orthopedic surgeons recommend vs. Prescribing these for knee oa b/c a randomized controlled trial showed no benefit; anecdotally, some people feel improved, some don't; take 1500/1200 mg g/c daily for many weeks to see if it works for you, talk to your doc about them.
What do you think about taking glucosamine and chondroitin daily not to cure but to prevent arthrosis and arthritis when you are still rather young?
Worthless. There is no data that these supplements will prevent arthritis. Save your money.
While it's not. Likely to hurt you there really is limited data to suggest any real preventative value. There is some evidence for pain relief but it is quite weak. You are better off making sure you eat healthy, remain physical active and keep a healthy weight.
Interesting. Questioner asks re: efficacy of glucosamine & chondroitin sulfate used long-term to prevent arthritis. The study has never been done & any medical doctor opinions about the worthiness or lack thereof of these these nutritional supplement therapies is meaningless. All humans are advised to feed their bodies natural substances critical for health & well being; the basis of Orthomolecular Medicine.
I have spinal stenosis, lately having hip pain that goes to groin, knee and down my leg. It's worse when walking, which I do daily. Dr said could be arthritis and said to take glucosamine/chondroitin. That doesn't help, any suggestions? Is this related to
Groin. I would see an orthopedic surgeon. You should have x-rays of your pelvis/hip. If the xray shows arthritis you can get a hip joint steroid injection under fluoroscopy or ultra sound guidance and physical therapy. If this doesn't work than it might be a spine problem.
