Glucosamine XL Plus w/MSM is rated 4.5 out of 5 by 28.
Rated 5 out of 5 by from Great Product I’ve seen much improvement on the way Breezy moves her back legs. She moves much better and not so stiff. Great Product!

Rated 5 out of 5 by from Very good! I bought this in July for my horse who went lame (hock problems) and decided to give it a try. I love it and have seen SO much improvement in his movement. I love that this supplement targets all his joints too!

Rated 5 out of 5 by from Perfect One-Stop Shop I've bounced around from joint supplement to joint supplement for various reasons. So far, this has been my favorite. It's the perfect combo I've always dreamed of. If you're a crazy person like me, you've read every bloody paper ever written on joint supplements for horse and effectiveness and results over time and different compounds doing different things. The trouble is, it's hard to find a supplement that supplies you with the recommended amount of MSM vs. glucosamine (and the right type of gluco!) vs. HA (if you want that in there) etc. etc. This one has it, folks - the perfect ratio of MSM to glucosamine with the CORRECT glucosamine compound for ingestion, not IM. If your horse is terrified of needles, but you still want the glucosamine, this is the stuff for you. Plus, it's just over $40 so it ships FREE in SmartPaks!

Rated 3 out of 5 by from AVERAGE I didn't see much difference in my gelding, but that may be a good thing. He was on a well known joint supplement and there was no change when switched.

Rated 4 out of 5 by from good combination supplement I purchased this product and found it to be a very good combination of glucosamine, MSM and Vit E that my vet recommended. Both of my older horses are doing well on it.

Rated 5 out of 5 by from Good buy I change joint supplements after several months for a horse that has chronic physitis-related arthritis. This supplement worked well, as he does better with glucosamine sulfate than the HCL; however, it lacks chondroitin, so I am going to try Exceed 6-way for a few months now. My elderly thoroughbred did find on this, but I am going to try Smart Combo Senior and hope the Devils Claw does not bother his stomach. Will see.

Rated 5 out of 5 by from Glucosamine XL Plus w/MSM We have been giving this to our horse to help him recuperate from being adjusted and sore muscles. It has definitely helped him heal and get stronger since he is not sore or in pain. We will absolutely keep giving this to George.

Rated 5 out of 5 by from Vet Recommended Purchased based on chiropractic vet recommendation, Glucosamine XL Plus w/MSM helped my horse recover from an ill fitting westerna and dressage saddle issues that resulted in stifle and lower back problems. After 2 weeks, vet noticed immediate results and now after 6 wks, the stifle issue is resolved and the lower back is reduced to muscle tightness that should be resolved in 3 more wks. Use product daily.

Rated 5 out of 5 by from Great Product We've been using this product for several years for my 20 year old Appendix. It has helped him to keep working...I'm trying the SmartPak Senior brand which includes the pro-biotic, hoping it will work as well, but keeping an extra bucket of this on hand for times when needs a little extra boost. Keeping him working has been the best for him, plus keeping him on a high-fat diet helps him to loosen up quicker.

Rated 5 out of 5 by from Worth a try! This product seems to be working on my aging pony.
