How long does it take for Glucosamine & Chondroitin to work?
It depends, for what exactly do you want it to work? Glucosamine and chondroitin are degraded in the gastrointestinal tract, so when they are absorbed into the bloodstream, they are in their digested form, in this form they won’t really integrate to your joints. That is why they are sell as supplements and not as medicine. They are placebo at best.
Some people will notice an effect within a few days, while others may have to wait up to eight weeks. Very rarely, I’ll hear of a patient who has needed 3-4 months to notice an effect. If there’s no noticeable improvement in pain or function after 8-12 weeks, I usually tell people to stop using glucosamine and chondroitin.
