Cosequin® Optimized with MSM is rated 4.8 out of 5 by 48.
Rated 1 out of 5 by from DO NOT PURCHASE I bought this product to give to two horses who needed MSM support. This is a powder with a strong smell/flavor. Both horses WOULD NOT EAT any grain that had been in contact with this product. They sniffed the grain and then walked away. You CANNOT return this product, so do not purchase this thinking you can return it if your horse does not like the powder. Neither of the horses being given this supplement are picky eaters, they were just put off by the smell.

Rated 5 out of 5 by from Vet recommended! Cosequin® Optimized with MSM is a staple for my OTTB with slight arthritis in his knee. This supplement was recommended by my vet to assist with a normal response to inflammation. I feed this product daily to help maintain joint health and have seen great results! My horse also loves the apple flavor of this powder.

Rated 5 out of 5 by from Just started using I bought this to start using as a preventative measure. We have a younger horse and I’m hopeful that this will help support his joints as we start working with him more for next show season.

Rated 4 out of 5 by from Seems to help, horse loves the taste I just wish it came in a pelleted form; its a super-fine powder and puffs of it get into my lungs every time I open the container and when I pour the scoop of powder into the feed pan. Horse does love the taste; I add it in a mash to flavor the rest of the no-sugar (ie no-taste) mash.

Rated 5 out of 5 by from What a difference in my mare! I have a 20 year old paint/tb mare and she has navicular and is starting to slow down a bit. This product saved my pleasure horse years ago and I immediately thought of it when I wanted some extra support for my girl. She has been on it just under a month and has made a fantastic improvement. She bends and stretches easier, turns smoother, and overall just moves better! Couldn’t be happier.

Rated 5 out of 5 by from Nutramax is a great company I’m using this on 2 horses for 2 reasons. 21 yo retiree to keep her comfortable. 10 yo lower level dressage horse for support. The 10 yo loves it and the older mare takes her time licking it up but does. I picked Cosequin at my vet’s recommendation.

Rated 5 out of 5 by from Great quality product! Preventative for my young horse! I use the dasaquin for my dog and saw such great results I had to switch my horses joint supplement to their brand!! Top of the line!

Rated 5 out of 5 by from Consistent, positive results. I started my 12 y/o KWPN mare with DSLD on this after having success relieving joint pain using Cosequin with my late-teens, ex-camp pony. My mare has pain in her hind fetlocks from the DSLD and OA in other joints from previous injuries. Her willingness under saddle has greatly improved over the last few months, she has much more freedom in her stride and is better able to use her back and hind end. She has her spunk and her sass back.

Rated 4 out of 5 by from Best product I've been using Cosequin Optimized with MSM ever since my mare was 3 years old, now she jyst turned 20. Sure there are many joint supplimenrs, many more expensive, but this is within my budget and I'm sure that she is better because of it
