I agree, some supplements work for some horses and some don't. It depends on each horse. I have had my friends try Consequin with no real result
With the age the horse is at, and how much you are working her I would consider injections with daily MSM.

Also keep in mind that the effects of a feed through supplement may be negligible. It definitely can't hurt but due to absorption rates you may not see much a difference and it'll probably take at least a month before you do see results. If she is as off and sore as you are saying it may be time to have a vet out to evaluate on a more serious level as far as injections etc. A feed through may not be enough at this point.
