My husband's gelding developed arthritis from an old injury and we
started him on Chrondroiton (sp?) Sulfate and it has really helped him.
Before he was on it, he would be fine as long as he was moving, but if
he stopped for any length of time, would be really stiff starting again.
Since we've been giving him this, he hasn't had any stiffness at all.
Hope that helps.

P. S. I get the CS from Springtime, I think they have the most
reasonable prices for the quality you get.
