Are glucosamine & chondroitin supplements effective for elderly people who suffers from spinal stenosis? And for runners?

Minimal benefits! Do not expect a miracle. Minor benefits may occur, but go with conventional therapy. But the only downside is a modest increase in blood sugar with these supplements! the spinal stenosis is mechanical and will not be improved!
They are safe the . Question truly is how effective they are but they due have some mild anti inflammatory properties .
