    Rated 5 out of 5 by from Great supplement! I love this supplement. I really believe this has helped my horse stay sound after his rehab from an old injury that he aggravated again. He feels strong and has great suspension at the trot. He's back to full work sooner than expected. I love that it's pellets so it's super easy to feed. Thank you SmartPak!!!

    Rated 5 out of 5 by from Excellent product I've been giving this to my 20 year old saddlebred for about 3 months. he is a great horse with a history of stifel joint issues. After the first month and a half I could see a definite change in his flexibility in his hind end.... Needless to say he will definitely be getting this product for the rest of his life!!!

    Rated 5 out of 5 by from Great joint support I have been giving this supplement to my 18-year-old eventing mare. She eats it without a problem and it gives her the extra nutrients she needs for her active lifestyle. The SmartPak service is great and easy.

    Rated 5 out of 5 by from Joint supplement My mare has been on this supplement for 60 days and I am very pleased. She is a 12 year old QH, shown regularly. I've noticed since on the supplement she now will trot around her turn-out and I've even seen her rear up playfully! Things she had not done since a 4 year old. I know she is feeling better. I would recommend this product.

    Rated 4 out of 5 by from Seems like a great product My horse has been on this product for about a month. He is currently on rest after tough Reined Cow Horse season. So truly I don't know if it's working. He seems comfortable. The service a SMartpak is great. He likes the pellets and eats them right up. Maybe I can add a comment after he goes back to work.

    Rated 3 out of 5 by from TBD My horse has been on this for a month and I haven't seen significant improvements, but the price is great and every horse is different. I will be trying cosequin if there is still no change in another month

    Rated 5 out of 5 by from Everything good for joints in 1 package! Started my horse on this, to help keep him fluid. Want to keep that pretty movement
    Date published: 2016-12-28
    Rated 5 out of 5 by from Great Product I have used SmartFlex III Resilience pellets for 6 years. I have an aging mare who has arthritis. I had talked to my vet about what kind of supplements to give her and I had been told to look for something that had specific amounts of each of the ingredients. This particular product had exactly what the vet suggested. My mare is a picky eater. But she eats this well. She has done very well with this product. Although now she is also on Equioxx, I am still happy with her SmartPak. She is comfortable and plays with her paddock mate. I had used her for trail riding and dressage, but now she is mainly retired. I ride once or twice a year.

    Rated 5 out of 5 by from Noticeable results within a week! I was sure I was going to be headed down the road of hock injections for my mare, but I've been amazed at the difference in movement and comfort for her within just a week of being on this supplement. I'm super impressed with the results, and I would definitely recommend this product!
    Date published: 2016-11-25
    Rated 5 out of 5 by from Super glad I bought this supplement! Let me start of with saying I don't believe that a supplement can compleatly change a horses ride. However this is an exception, I got this for my mare as a support supplement, so she would never really have discomfort in her joints and to help keep them healthy. So after a month of being on them I gave her a weekend off to rest from her usual hack everyday for about an hour. I got on her at the being of the week and she felt like she just floated around the arena, she kept this feeling all week with me riding her every single day. They made a big change in her movement and comfort in the arena, super glad I bought this supplement!

    Rated 5 out of 5 by from My mare acts like she is 5 years younger I started this 2 months ago and the difference is amazing...my 15 year old mare acts like a youngster not a season show horse.... she feels THAT GOOD!!

    Rated 5 out of 5 by from Worked exceptionally well! I have been struggling since last February with tendon injuries and just was not finding anything that was sustainable. After researching that tendons needed nutrition in the form of certain collagen, I saw your product and wanted to give it a try. I was AMAZED! She is a 16 year old Quarter horse and this is the second month of using SmartFlex III Resillience. The glucosamine was also an added benefit to the product. It worked fast; I noticed she was no longer in any pain and both legs healed up dramatically fast with no swellings/puffiness. She is my dressage horse and we also trail ride. Very happy with the product.

    Rated 5 out of 5 by from Works great! My 12 year old mare was starting to act I bit stiff in the hind end when we started upping her work to event. Never lame but just a little stuck, when eventing season ended I decided to start her on some joint supplements to see if that would help. I had plans on getting the vet out to see if we needed to start doing some joint injections as well. 3 weeks on this and she was 75% better, I couldn't believe the difference in that short time. She did get her hocks injected but I will be keeping her on this as well long term!

    Rated 5 out of 5 by from Stepped up to resilience due to some chronic tendonitis.

    Rated 5 out of 5 by from Finally Seeing Results My horse mysteriously went chronically lame about two years ago. We had no idea what the issue was. After a year of no work, padded shoes, joint supplements, etc. she was finally sound most of the time, but even then it wasn't a guarantee. She was previously on Cosequin ASU. It was working fine but there were still days she came out stiff. Last year, I pulled her shoes, put her back into work, and started her on this supplement. She is better on this supplement than anything else. We can tear through rocky trails and steep hills for hours. Gallop through the fields at full speed. I was prepared to never be able to seriously work my horse again, but here's to many more, sound, adventures together.

    Rated 5 out of 5 by from Horse Hasn't Been Stiff I have had my horse on these supplements for a while now and lately he's been stuck in the stall due to poor weather conditions, not been stiff at all. He is exercised 6+ hours a week and jumps 2 days a week, he used to get soar in his legs after a workout and after a month of using these he hasn't gotten stiff.
