Joint supplement question?

My TB mare has been fairly stiff lately and there is a lot of snap crackle pop when she first gets moving around. I currently have her on a glucosamine and msm liquid supplement (Next Level Equine Joint Supplemnent) which I just started a few days ago and bought because it was the only one available at our local tack shop and I wanted to start her on one asap. But I am also thinking I want to put her back on a hoof supplement as well, she was on one up through late fall and I discontinued use but lately am not as satisfied with her hoof quality. I also would like to keep these realtively inexpensive. I don't want to buy a crap product though I want it to actually work. So what is your favorite/ most effective product for hooves and joints? A product that does both would be even better! Thanks for reading!
