    SmartFlex® III Resilience Pellets is rated 4.6 out of 5 by 522.
    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 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!

    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 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 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.

    Rated 1 out of 5 by from I tried to give this to my horse but unfortunately he would not eat them and refused to eat his feed with this supplement in there. To double check, I tried to hand feed him the pellets alone and he spit them out pronto! I was curious and I tried a couple and I did the same thing lol!

    Rated 4 out of 5 by from So far so good.... I started my young stallion on this product during his initial breaking and training period. I have had other horses with OCD and other issues so am aware of how growth rates and work intensity can affect a young horse. He is out of training now and is being ridden to maintain but not everyday or near the intensity of training. I am pleased with how he continues to move and stay sound and am waiting to see if this product can put off joint injections that are so commonplace in today's equine athletes.
    Date published: 2016-06-10
    Rated 5 out of 5 by from Noticeable improvement I am a farrier, and became interested in this product line and noticing some changes in a few of the horses I work on. One of my personal mares has very minor OCD in her right hind, and because of that struggles to pick up her left lead. On both this supplement, and the Senior joint supplement (I have used both at different times), I find a noticeable improvement in her willingness to pick up that lead.

    Rated 4 out of 5 by from need time to know if it works Horse has crepsis and arthritis at age 7! No lymes, just stiffness. After 6 weeks it seems she may be responding, but I need time to be sure. It's now warm out and she's on pasture, so the effect of supplement isn't clear. She does eat it.
