Rated 5 out of 5 by from Pony doing great! My granddaughter’s pony was beginning to show some stiffness in her hocks. She was never lame so the vet suggested a supplement for her. She has been on them for awhile and is doing great!

Rated 4 out of 5 by from Gave my horse the relief he needed I purchased this a bout two months ago to help my horse stay comfortable and healthy as we increased out training, with in a month I noticed a positive result in the way he felt and moved. Great product for the price.

Rated 5 out of 5 by from Does the job I started my 13 year old horse on these to help support his joints as we start moving up from 3rd level Dressage. My trainer has already noticed a difference in his comfort and ability to sit.

Rated 4 out of 5 by from Starting to notice a difference I started my 14 y/o Morgan mare on this about 2 months ago. We just got into jumpers this year and I wanted to give her more support than just the regular MSM I had her on since her workload is the heaviest it has ever been. She started becoming sore the day or two after competitions and her legs were really swelling up with the summer heat, so I looked into a different supplement. (As well as putting shoes on to help support her as she has been barefoot for quite awhile!) Recently, I've taken notice to the fact that she's been a lot more comfortable coming out of her stall after being in on hot days and I've heard much less cracking / popping noises as well. I am definitely going to look into SmartFlex Ultra next show season, as we are at the end of our season now, to give her even more support. I gave 4 stars because I have her on Adequan as well, so I think the combination of these two things are helping keep her comfortable and competing. All in all, I think this product is doing well for her.

Rated 5 out of 5 by from Joint Support During Hoof Rehab I don't even know if I should be writing a review this early, but something I saw today compelled me. I have been rehabbing my TWH mare's hooves since I got her nearly 5 months ago. she is recovering from long toes and crushed heels, that cause toe first landing, with foot hitting the ground before legs fully extended. At her worst, this caused instability in her foreleg joints all the way to the elbows. Just recently I bought this product to helr joints, which have likely been under tremendous stress. The product arrived within two days of ordering and the shipping was free! The mare has been on the supplement less than a week. I observed her walking purposefully in the paddock today and saw her put those front feet down so solidly heel first that I was gobsmacked! It just can't be that she suddenly hit a magical platform in her hoof recovery! The change is too dramatic. I am going to give this product a lot of credit for the sudden improvement in my mare's ongoing recovery.

Rated 5 out of 5 by from Easy Buffy hates most joint supplements. She doesn't get grain, so it can be difficult to get her to eat her supplements. No problems here.

Rated 5 out of 5 by from No more cracking Has helped my mare with her cracking. Also helps with the inflammation ...
Date published: 2019-05-09
Rated 5 out of 5 by from Great Maintenance I started my 10y/o ottb on this supplement two months ago as a maintenance supplement. He is never lame or sore, but figured it wouldn’t hurt since we will be moving up in jumping and flat work starting this year. After two months I can say he feels better than ever, and I didn’t think he could get much better! He has a bit more energy, but that’s most likely due to feeling great!

Rated 5 out of 5 by from She likes it! I believe it's helping with her joints popping and cracking.

Rated 5 out of 5 by from Sore No More My mare has been taking this supplement for a few months. She and I do lower level dressage work, grid work, a lot of trail riding, and field work. The difference in footing, age, and normal wear on her joints often leaves her sore and stiff. This is very apparent when she is left in a stall overnight and brought to work in the morning. Since putting her on these supplements it’s much less often she seems stiff in her joints. I’ve tried her on other joint supplement and nothing has worked as well as this one.

Rated 5 out of 5 by from Great product, great people! My horse Jackson began to show some stiffness, so I reached out to SmartPak for thr appropriate supplement. After exchanging emails I started SmartFlex. I added SmartCalm because show season is coming. Jackson loves his SmartPak. Today my youngest grandson helped serve him

Rated 4 out of 5 by from Solid support I am using this on a semi-retired 8 yr old gelding who has a stifle issues. Horse is field boarded at friend's farm and ridden occasionally in warm weather. Main purpose of feeding it is to help his overall comfort. Seems to do it's job and overall horse is doing well. However, he does not get ridden long or hard.

Rated 5 out of 5 by from Joint Pellets I started my 15 year old gelding on this in December, and I can already see that they are helping him.

Rated 5 out of 5 by from great ingredients Have a young x barrel racing horse that has a bum shoulder has trouble when turning to the left. She has been on SmartFlex Pellets for almost a month have noticed much improvement. She is stepping out better and tearing around the pasture like a young horse should do chasing her 30 year old brother and 17 year old sister making them move. The other day she came high balling around a gate into the back pasture thought oh no she would come up lame from her antics but she stayed sound. THANK YOU SmartFlex Pellets.

Rated 5 out of 5 by from Great Product for the Price! Switched my QH/TB gelding to this from Cosequin ASU. This product is much cheaper, easier to feed, and works just as well, if not even a little better.

Rated 5 out of 5 by from Best value around I switched to this after a price increase on my then current joint supplement and couldn't believe how much I'm saving and it's not super messy like the liquid I was using ++ for everyone.

Rated 5 out of 5 by from Helps so much! My mare has been on this for 2 months now and she has never felt better. no stiffness in her back legs which has made getting back into work, and shape, into a much more enjoyable experience.

Rated 5 out of 5 by from Made a big difference! My 9 yo rescue gelding was showing signs of soreness in light training. I had my vet/chiropractor out and she adjusted him, and suggested we get on a joint supplement to help maintain him. After several months of SmartFlex, I am very happy at how comfortable he's been. I signed up for the automatic order, and love the discount! You can't beat Smartpak's customer service either.

Rated 5 out of 5 by from Smartflex pelled My horse had a previous shoulder injury and was very lame. A friend recommended the smart pack supplements. She's been on them for 2 months and I am happy and blessed to say this product is helping so much.
