Product Overview

Which horses benefit from comprehensive joint and soft tissue support?

Your horse’s body has the ability to repair and rebuild after normal “wear and tear” from light activity, but the increasing demands of riding and training could cause more damage than it can keep up with. Joint supplements in this category are designed for horses in heavy work to help support your horse by providing a steady supply of the ingredients he needs to cope with the demands of his workload. This level of support is also worth considering for horses in lighter workloads that may benefit from additional support due to factors like age or previous joint issues.

SmartFlex® Ultra Pellets is rated 4.6 out of 5 by 597.
Rated 5 out of 5 by from Great joint supplement! The smart flex ultra pellets were exactly what I was looking for as an added maintenance for my adult hunter! With show season coming up my horse can use all the help he can get to stay happy and healthy!

Rated 5 out of 5 by from Great ingredients with evidence to back it up! I like this supplement so far, I feel like I’ve seen some results already and I’m hoping those results will only continue to improve.

Rated 2 out of 5 by from No Improvement in Horse I have had my 14 y.o. Appaloosa on this product for 4 months and the 5th month is on the way. I will be canceling further orders as I have seen no improvement with my horse. He passed his PPE at purchase in February, 2021, (but I was advised he was 'pre-arthritic' ). I started the product in March, 2021. I figured a new horse, new life so let's get him on something. After a lot of research I picked this product with care. Unfortunately, it just hasn't worked. He is still 'stiff' when he starts a trail ride and hasn't improved much. I really wanted this product to work, but it has not. I feel after finishing this 5th month it is time to try something different. The price is reasonable for this type product. It may work for other horses but not mine.

Rated 5 out of 5 by from Seems to help I have my current dressage horse on this as a maintenance product and she really has no issues. I've also been feeding it to my retired 25 year old FEI horse. It has made a difference and he seems less stiff and more comfortable. He was retired due to severe tendon injuries so he's not always sound, but any increased comfort I can give him is worth it. He is also SUPER picky and eats it up. I love the convenience of smart paks, so I know they get their supplements.

Rated 2 out of 5 by from No improvement I was hoping this supplement would work for my horse based off reviews and what other peers have said. Previously was on cosequin ASU plus but wanted something more cost efficient. His mobility have became significantly worse over the past three months. Really wanted this to work but unfortunately cheaper doesn't mean better.

Rated 5 out of 5 by from Quality you can see I have an 18 year old thoroughbred that is loving life and still working hard. I put him on SmartFlex Ultra to keep him comfortable before injections this summer for jumping but he is currently traveling really well and happy to work!

Rated 5 out of 5 by from Works a lot better than ASU Plus I've had my boys on this product for about 5 months, after years of using Cosequin ASU Plus. Since changing, my gelding with a gaming history before I got him along with a bad hock has improved tremendously. Before, I would have to use Sore-no-more on his hock prior to his trims. Now, no problem. Before, when even having that hoof picked out he would kick back when I let hit down due to the pain. Now, no problem. My other horse is moving much more freely than before. This is an excellent product.

Rated 3 out of 5 by from Very good product Been usuing for the last several MN cold winters in place of Vets RX Previcox for arthritic pain. Found the product ads great deal of comfort without using more costly product. It is worth reasearching and trying products to help your horse and buget. The horse will show the end result and that is how we decide which additive and or supplement ingredients to administer to our horse. Very pleased with results, seems to ad relief of arthritic and stifle diagnosed symptons to older horse.

Rated 5 out of 5 by from Definite improvement My mare has been in this for a month and half now, and my trainer and I can both see a definite improvement in the way my mare is moving. We decided to put her on it after noticing that she was tight in her stifles. Plus she eats it right up, which is a win!
Date published: 2020-12-14
Rated 5 out of 5 by from Whole new horse My horse has been on this for nearly 3 months now and he feels like a completely new horse. He would trip behind frequently before and now he doesn't trip at all. He actually carries himself for the first time in a long time. He's 19.

Rated 5 out of 5 by from game changer ! My vet reccomend i switch to a joint supplement after my gelding had some back and hock issues. after switching to smart flex ultra, i cannot even tell that he had any previous issues and is performing better than ever!
Date published: 2020-10-21
Rated 5 out of 5 by from Ultra good supplement! My mare has been on SmartFlex Ultra for 3 months, we just received our 4th month of smartpaks. I made the switch from her previous supp AND smarttendon AND msm to feed just smartflex ultra. Our most recent vet checkup (now 8 months from initial) for her suspensory tears and she is looking great, I am very glad I supported her with SmartTendon and SmartFlex. I will now be switching her to SmartStride Ultra for the additional anti-inflammatory support and higher levels of silica and collagen. We discovered she has a few abnormal spots on her front left navicular bone and since I do get to put her back into work, I want all the support possible for my unicorn. She has been super patient and wants to go back to work, I'm all for it and luckily SmartPak has something to help us with all the curveballs we've encountered. I 100% recommend this product if you are looking for all-around support and the ability to feed 1 thing instead of 3.

Rated 4 out of 5 by from I liked smart pal combo ultra better... I tried this over combo ultra bc of price but I think I will go back to the ultra.

Rated 3 out of 5 by from Easy to use Very easy to use and I love the auto shipment option, however this particular product just didn’t work for my horse.

Rated 3 out of 5 by from havent really seen any changes got both my horses on this- and for their weight. im a month in and dont really see any changes. gonna change to another one. i love rehab but will test positive

Rated 5 out of 5 by from Incredible results So I had my horse on Cosequin Optimized, and while it worked for a while, its just not enough for him. So after reading countless reviews about SmartFlex Ultra. I though it was worth a shot. Wow the results were noticeable after about week, Fagan is able to bounce back after a hard ride without being sore the next day. His strides are more fluid and he feels better overall.

Rated 4 out of 5 by from easy to feed complete joint supplement These pellets are very palatable, my horse eats them right up, no powder left at the bottom of the bucket and they have all the joint supplements research supports for good joint health!

Rated 5 out of 5 by from Took Her Off - Never Again! I had my 12 year old OTTB on this for years. Took her off because I thought I should now go with a “sexy name” supplement. Never again! She immediately started having problems, needing steroid injections in joints, etc. I’m going back to Smartflex Ultra right now! Not sure there’s a connection, but after $1500 in vet bills I’m going back to what worked so well for her.

Rated 5 out of 5 by from Incredible supplement!! Our gelding suffers from stiffness in the colder weather & the supplement we gave him just didn’t seem to be helping any longer. After lots of research & outstanding results from other Smart Supplements, we switched him to the SmartFlex Ultra. He’s been on it for a little more than 3 months now & the difference is noticeable. His rear end isn’t stiff, making him a much happier camper.

Rated 4 out of 5 by from I bought these for an elderly mare with some joint problems. Unfortunately they have not helped her, however I used the left overs from the 3rd month to a retired race horse that just needed a little help and they done fabulous!!

Rated 1 out of 5 by from Charged two prices for the same supplement I had one horse on the Resilliance 3 and was "grand-fathered in" at $65.87 and another horse on SmartFlex which is EXACTLY the same product as the old Resilience 3 at a price of $57.96. When I called Smartpak, the representative there went through the ingredients with me and varied the two suppliments had the same ingredients. Smartpak did not have the decency to contact me and say I was paying two different prices for the same supplement. Rather, they led me to believe I was paying a lower price because I was "grandfathered in". I feel this is bad customer service especially when my barn purchases over $1000 in supplements from smartpak each month. I am writing this review to make sure you are not being overcharged for this product whether you have one horse or many. SmartFlex is the old Resilliance 3 but is cheaper! I would appreciate Smartpak crediting the over-charge that I have been paying for over a year to me and any other customers that have been "grandfathered in". I do like the product and would like to give it a good review, I just feel like Smartpak needs to be honest with its customers about the products they are selling and make this right.

Rated 5 out of 5 by from Quick Results - More Benefits than Expected I bought this about 3 weeks ago and put my 20 year old warmblood mare and my 15 year old BLM mustang gelding on it. Neither had any known injuries they were actively healing from but my mare was definitely getting creaky and I noticed she seemed to be protecting a knee and a hip a bit more and I just thought that extra support for her tendons would be a good idea in case the pain wasn't just joint related. My mustang is a muscle powerhouse but he's been having trouble getting into the Piaffe lately and I again just thought a really robust supplement might help him to be a little looser and freer. I saw results in the Mustang within a week - more fluid movement, quicker warm ups and it just seems like its easier for him to "put himself together" in his joints and that everything is more comfortable for him. I noticed it in the mare in her skin and coat first, within 2 weeks she was a little shiner and less dry (she does recieve an omega supplement every day already, as well, but i think the extra vitamin c and other support in this supplement kicked her up a notch nutritionally) and on week 3 I am noticing that she is starting to move a little freer in her hind end and I'm not noticing the shaking in her knee like I was a few weeks ago. I'm excited to see what a couple more months of this supplement will do for her since I think she probably needs more "umph" than he does. I'll likely "drop them down" to just the senior SmartPak supplement after a couple of bags of this, but I'll tell you, I'm very pleased with the results and consider it money well spent.

Rated 5 out of 5 by from Seems to work! I can tell a difference in my 14 y/o OTTB that has a body of a 20 + from having over 50 starts, to competing in eventing and now as a lesson horse, this boy needs the joint support. He arrived on my farm September of 2017 cracking and creaking every step he took. After a vet examination, they recommended being put on a joint supplement, so after a lot of research I tried Smart Flex Ultra and I have to admit, it took several months for me to tell a difference but I DID tell a difference this summer (2018). No more creaking and cracking!

Rated 5 out of 5 by from The Best Supplement for our Polo Horses! We have been using this supplement for years for our polo horses with great results. We take extreme care for fitness and health of our string, and this is the best option for us to ensure we maintain healthy joints and tendons.

Rated 5 out of 5 by from Finally lost the limp :) She’s been on it 3-4 weeks, she also had 30 days of stall rest. She’s doing better, i think it’s from the combination.

Rated 5 out of 5 by from Great results My QH would stock up after every ride. The vet said that some horses just do this and as long as she wasn’t lame or showing pain, not to worry about it. But I did. I started her on Smartflex Ultra and voila’. No more fat ankles. I’m so very pleased with the results. She is also loving the taste and she is the ultimate picky eater.
