    Advanced Cetyl M® Joint Action Formula for Horses is rated 4.8 out of 5 by 116.
    Rated 5 out of 5 by from Worked for us! I started giving this to a semi-retired jumper. I had permission of the owner but didn't say when I would start. After the horse had been on it for about 2 weeks, the owner said that the horse was more sound than he'd seen him in years. And I noticed that the last time the horse had a jumping lesson, his hock did not swell up like it usually did. I've had no problem with palatability - he gobbled it right up.

    Rated 5 out of 5 by from Amazing!! I've had my 12yr old OTTB for 18mos and although sound and with no major issues, he has always appeared stiff when moving and dragged his back hooves. Many times (even at a walk) his right, rear fetlock joint seemed to "snag" and he would stumble a step before it would right itself. The vet could find no injury or serious issues to his legs/joints, etc., but felt that he definitely had arthritis d/t his early racing days, which is quite common. After doing much research and speaking to my vet, I decided to start him on Cetyl M because the research and success stories seemed unmatched by other joint formulas on the market. I gave him the loading dose for the first 28 days and then continued with the maintenance dose. WOW!! After 3 wks on the loading dose I noticed that there wasn't any "clicking" or "popping" when he moved at any gait. He was quicker to move out without needing to warm up and the stumbling had disappeared. The vet described his trot as "beautifully floating!" I just can't get over how wonderful he looks with movement and I can tell he feels better without all the stiffness. He takes the opportunity to chase and play with the other horses, whereas before, he really seemed to think twice and then moved minimally...just enough to keep them away from his hay!! Lol! This is by far the BEST money I've spent on supplements!! He will be on the Cetyl M for the rest of his life. I've heard people claim it's too expensive. I haven't found it to be much more expensive than other high end joint supplements by more than a few dollars a month. Well worth it and it WORKS! I would highly recommend it to others! As a side note~ My horse isn't a picky eater at all, but when I first started the loading dose I mixed the granules with a little water and gave it to him with his grain and he turned his nose up at it and refused to eat it. I think the super, sweet smell turned him off. I tried splitting up the dose to AM & PM and addling chopped carrots & apples. Better, but not great. Finally, by the third day, I mixed the granules in with a snack size applesauce and added that to his grain and VOILA! He gobbled it up and not a speck was left in his feeding tub! Also, I found that the applesauce is a great medium for the granules. It binds it together into a great paste and I know he's getting it all. Hope that helps!

    Rated 5 out of 5 by from Great joint supplement I was convinced by a rep at Equine Affair Ohio to give this product a try. And Smartpak was doing a wonderful promotion at the event, so I signed up for my first smartpak. My warmblood is 9 years old in heavy work (min. 6 days/week). I decided to start joint supplements as a preventative. I used to feel that my horse had a weakness in his right stifle, evident by the fact that it was really hard for him to sit back for movements like 15m counter canter circles, followed by what can best be described as a "giving out" of the stifle (not a catch or locking). Since I started the supplement (about 2 months ago) it seems that this problem has gradually gotten better. It happens less and less. I love that it is all natural ingredients too.

    Rated 5 out of 5 by from great product I have 8 horses and 2 dogs on Cetyl M and I am very impressed! I think in the future pellets might be better then powder, but all my picky eaters lick their buckets clean and they are sound. (Knock on wood)

    Rated 4 out of 5 by from This stuff does work I originally tried this product for a mare diagnosed with irritation of the navicular bursa. She just couldnt come sound, and 10 days after the loading dose she did. She did exhibit being a little sore when I dropped her from the loading dose to the maintenance dose, but after a week she went sound and stayed sound. I did try to take her off of the supplement when I bred her this year, she went lame. She didnt get pregnant, and now that she is back on the supplement, is now sound enough to work 4-5 days a week. We have now put 2 of our "senior" geldings on the supplement, and do see a positive difference in their soundness.

    Rated 5 out of 5 by from Yeah! she eats it! My picky eater Mare is eating her supplement and moving like a youngster. I am happy with the results I have seen. My Mare comes out and works consistantly every day. She is no longer showing signs of soreness.

    Rated 5 out of 5 by from Horse loves it My horse loves the Cetyl M - I went with this product because my veterinarian recommended it. My mare was not having any problems that I had noticed - but she is 15 and I want to help her joints as she gets older. It is easy to give and a side benefit I have noticed is that her mane and tail have gotten surprisingly soft since on the Cetyl M. All in all I am happy with the product. No complaints.

    Rated 5 out of 5 by from Helps I think this is working for my 21 year old Mule with ringbone. He's getting around, and I don't want to not give it to him as a test and have him be worse. I take a supplement with Cetyl M, and it's makes a trememdous difference for me, so I give it to all my horses, and dogs, as well as myself. Trish

    Rated 4 out of 5 by from great product my horse is young but as a 3 yo we had to have his hocks injected. the vet said his hocks were really dry w/very little lubricating fluid. hock injections are very expensive so we had to look for other alternatives, trying many different products. so far the cetyl m has been the best. it is affordable and my horse loves it.

    Rated 5 out of 5 by from It has put a barrel horse back in in the arena When your vets tells you that a horse never will give you a hundred and fifty percent any more, but she will still give you a hundred and ten...she is worth saving to every person around here because of her heart and determination. She has some poor confirmation, rather large rear end and danty head, she has always been an accident waiting to happen. She is never still, never quiet, and always running everywhere! After a major barrel race she came down with a swelling on her knee, yet no pain. She was examined by the vet but no major damage was expected. A month later she became lame on that leg. She had broken a bone in the lower knee joint and caused some major injury to the tendons behind the knee. Though she may never return to barrel racing, I wanted to her feel well enough for the next twenty years to bully everyone in the pasture. She was placed on cetyl-M and it has brought 80% soundness back to that leg. Our plans are to keep her running fit to keep the knee strong yet let her be a horse. She is a very picky eater. I dumped a scoop in to her bucket and she would not even approach it. It has a rather strong sweet smell. So for a week I would sprinkle a small amount on her feed and a little more the next day. At the end of the week she excepted the supplement like her normal feed.

    Rated 5 out of 5 by from This product delivers I first gave Cetyl-M to my 10 year old beagle who was having terrible problems with his hips after being run over by a cyclist. He could not put any weight on his left hind leg for months after the accident. After 3 weeks on the C-M, not only was he running on all fours, he could jump up and down from my bed that stands about 3 feet tall. He has been pain free for three years now. So when my horse developed stifle joint issues, I put him on it as well. That was over two years ago, and he has had no problems since. This product is the real deal.

    Rated 5 out of 5 by from it works Started my 7 year old home bred mare on it in January. She had developed a stifle issue which was causing her discomfort and lameness at trot and canter. I saw a significant improvement within 12 hours of the first dose. I have been able to return her to light arena work and 2-3 hour trail rides, which since I ride like an old broad these days works just fine for me. I am thrilled

    Rated 4 out of 5 by from Tasty! My horse had his hocks injected within weeks of starting this supplement. He has been on other top joint supplements for the last three years. None contained CM. I cannot see any difference yet but I am hopeful. CM is so tasty that my horse will eat it without feed. OmegaHorseshine is the only other supplement that compares in palatability.
    Date published: 2011-04-22
    Rated 4 out of 5 by from good very palatable. two horses have eaten it well and although I don't have objective evidence, I do believe they seemed more comfortable after two weeks on the product. I think it's expensive and apparently the price is going up as the company is increasing the amount of cetyl m in the product. I wonder what their evidence is that this is needed as it does increase the price on an already pricey product.
    Date published: 2011-03-25
    Rated 5 out of 5 by from Amazing supplement I waited to review this supplement because I was not sure whether it was the Cetyl M or the HA that I added at the same time that was responsible for my 19 year old arthritic OTTB's drastic improvement. He looked great all winter. To test whether the Cetyl M was helping, I discontinued using it when the tub ran out. A few days after I stopped the Cetyl M, he started looking (and feeling) terribly stiff. He was especially stiff in his left hock, and he was also off in a front foot that has some arthritic issues after I rode him. A few days after re-starting the Cetyl-M, he is looser, more limber, and SOUND! I do not know how it works, but I guess he is on it for the rest of his life.
    Date published: 2011-03-20
    Rated 5 out of 5 by from I am convinced I got a new mare that was diagnosed on the prevet to have some significant navicular inflammation. We followed the vet protocol, but just couldnt get her 100% sound. The mare has been on Cetyl M since November of 2010. After 10 days of being on the loading dose, went sound. She did go lame for a week when I reduced the dose from loading to maintence, then went sound and has been sound enough to be in full work. I even jump her! I was very skeptical of this product when I started her on it, but I have to say, it has made a believer out of me. The smell of this product is so nice, I want to eat it! It really smells yummy!

    Rated 5 out of 5 by from Saved my Gelding's show career When my trainer found my gelding, he was lame. Lame, Lame, Lame. He is a 16.2 hand hunter type QH. His owner did not want a hunt horse, so he went to a trainer that forced him to be something he was not- a western pleasure horse. His hocks had scheduled injections every 3 months. He was cranky, in pain and needed to be sedated to do most anything with him. My trainer saw something great under this gimpy/cranky exterior, and I bought him. I knew about Cetyl M, and thought my gelding would be the perfect candidate for it. It has been a year since my gelding was started on Cetyl M (and ONLY Cetyl M for supplements), and not only has he NEVER needed a hock injection since, he LOVES the stuff! It literally smells like a fruit smoothy. When we go around the show ring, I always hear whispers of " that horse was lame! He never could canter.." Not only does he canter, he is usually walking away from the ring with a blue ribbon! Now almost all the horses at our barn are on Cetyl M, and it is working it's magic on them too!

    Rated 5 out of 5 by from Excellent Product I have had my horse on this product for 9 months now and before she had alot of lameness due to a stifle she has alot more movement and dosen't seem as stiff like she was before using this product. I have tried cheaper supplements but they just don't give me the results she gets with Cetyl M....I deffinately recomment this product to anyone who has a horse with joint lameness issues.
    Date published: 2011-02-24
    Rated 5 out of 5 by from Best stuff since sunshine I first discovered Cetyl-M when my mare was still with me... She was extremely arthritic in her hind end, so much so, I couldn't ride her anymore as she was so stiff and obviously in pain. Since I wasn't ready to part with her yet as she was the love of my life, I tried everything I could think of short of injections (she hated her legs being messed with so I wasn't going to torture her like that) I tried Next Level, MSM, Condroitin, Cosequin, all type... Some helped, but not enough ... I saw the commercial for the dog w/ arthritis, and decided to try it. It took a while, but within a couple of months I was seeing a noticable difference, within 6 months we were riding again, and she was happy. I kept her on it until the end of her days, (she was 29)She went from being slow and sore to what my friend described as " Crazy" because she just started running off with her one day... I was shocked but ecstatic that my girl was feeling her oats so well she could keep up with the youngsters. I now have my 25 yr old gelding on it and am anxious to see how well he does with it too... He's not as bad, but he injured himself, and I figured it couldn't hurt to keep him healthy :)

    Rated 5 out of 5 by from My horse was recently diagnosed with a stifle issue. Injections with cortizone did not make much difference. I noticed a significant improvement in her gait and being able to use her back 12 hours after giving the first dose of Cetyl M! That was 3 weeks ago and she continues to maintain the improvement. I am thrilled.

    Rated 5 out of 5 by from It works! I have a 16.3 hand Friesian who needs joint support. I've tried many, many products over the last 10 years. Some have been okay, some didn't help him at all. This product is fantastic!. I could feel how much softer & looser he was after one week on this supplement. He's been on it now for almost one year and I'm staying with this one. The stiffness is gone. Such a different ride now. I highly recommend it.

    Rated 5 out of 5 by from noticeable difference I noticed a difference in horse's movement within the first week. Now seeing consistent smooth, relaxed movement, even fresh out of the stall. I did not see these results with any of the many other products tried. Palatability is very important with my horses, but they love this...I love the smell...should try it myself!

    Rated 1 out of 5 by from Tasty but ineffective I am slowly working my way through all available joint supplements to make sure I've tried everything I can to help my arthritic 35 year old gelding be as comfortable as possible before I have to make the decision to put him down. Despite being a supplement skeptic, about 7 years ago I started him on Senior Flex and to my GREAT surprise, noticed a distict improvement in his mobility and comfort level. About 4 years ago I switched to the Smart Senior because I wanted a product with digestive and immune system support. He did quite well on that product as well. Last winter he became noticeably more painful so I added bute, which helped tremendously. This summer he started gimping again, even on daily bute, so based on the rave reviews from other users, I switched from Smart Senior to Cetyl M. Despite keeping him on the "loading" dose for 2 months, I noticed no improvement. The best thing I can say about Cetyl M is that is smells yummy (my husband was tempted to taste it because it smells so good) and my old guy really seemed to enjoy eating it. However, it was an expensive flop as a joint supplement. I now have him on (and am seeing good results from) Cosequin ASU - despite that the Cosequin ASU is significantly more expensive, it provides a better value because it appears to actually work. Obviously every horse and situation are different, but based on my experience, I would never purchase Cetyl M again...unless I had a picky eater and was desperate for something that would entice him/her to eat!

    Rated 5 out of 5 by from Seems to work My mare had some inflammation in her feet that was diagnosed via xray. We tried other supplements, and corrective shoeing, but couldnt get her 100% sound. I put her on this, and there is a positive difference in her soundness. Its too early to tell if this will help her become 100% sound, but I am optimistic it will.
