Chondroitin Sulfate is dosed at 100mg per serving. It's most notably associated with a landmark glucosamine-chondroitin combination trial published in the New England Journal of Medicine -- but that trial and related research commonly used around 1,200mg of chondroitin daily, roughly twelve times what's in a JointReliveX serving. That doesn't mean this amount does nothing, but it does mean the research most often cited for chondroitin doesn't directly transfer to this specific dose, which is worth factoring into how long you give this a fair trial.
