    SmartFlex® III Resilience Powder is rated 4.6 out of 5 by 222.
    Rated 1 out of 5 by from Not happy I received an email stating exciting news about my horses current joint supplement. Well it wasn't exciting, it upset me because my horse is RED flagged that he cannot have alpha and that I had researched with your employees to verify the ingredients. The powder is extremely dusty and has to be wetted down with his food, so he can consume his meal without sneezing. I may have to do some research and find another product or company.

    Rated 3 out of 5 by from So far so good So far, so good. I've been feeding this for about 2 weeks. My picky eater is definitely eating it! I can't say that I see a difference either way, though we'll see what happens because getting him to finish his food or supplements is half the battle!

    Rated 5 out of 5 by from My Morgan Moves Freely. I bought this a little while ago. At first I thought may not be working as I still heard the creaks. However, vafter about 3 months I am glad to report she no longer needs oil in the tires.If you have patience this will work. Thanks SMARKPAK you did it again.

    Rated 5 out of 5 by from Great supplement I love this product and have used off/on for a while. It is a bit pricey though. Just switched my guy over to the pellets, which I use on both of mine. Currently dealing with a ligament strain which I am hoping this helps with.
    Date published: 2016-06-10
    Rated 5 out of 5 by from great product I tried this product after my horse had been having various ligament issues on and off over a 3 year period. Even with great care being taken it seemed like bad things kept happening after a several months of work, often minor but enough to disrupt riding and training for weeks at a time.I had tried other products but saw little or no difference. I liked that this product has the grapeseed, collagen and silica in addition to HA and the standard MSM etc. I wanted something that offered more support than Cosequin but not all the extra ingredients in the Smartflex-rehab. There was another smartpak product (no longer being made) that he proved allergic to in the past so I wanted to keep that potential to a minimum - which is also why I wanted the powder instead of the pellets.SmartFlex III Resiliance is expensive but it really made a difference. Not only has my horse been sound and comfortable but he feels so good that he is a little bit "high", but in a good way. As a dressage horse aiming for the top levels I want my horse sensitive but not explosive or spooky. I have found him to be more eager to work, lighter off my aids, and having more energy while remaining focused. It makes for a really fun ride. He is using his body more correctly and easily too so I know he feels great. He was never like this in the prior 6 years. I can't wait to see the long-term results.I went with the powder because my horse isn't that picky and I wanted the purest form as he is terribly sensitive and allergic to many things. He gobbles this up (I add a little liquid to make it stick to his grain) and has had no adverse reactions. This stuff smells really yummy, like grapes. I wish they made a human version so I could feel this good!

    Rated 5 out of 5 by from Great Protection! I started my 3 year old gelding on this as soon as I bought him because he had previously gone through a fence and had a serious injury in one of his legs. I want to support him in the best way I can, and this supplement not only supports his joints, but also his tendons and ligaments. Because of that, this is something I will continue to keep Lex on!

    Rated 5 out of 5 by from Happy Horse I had smartpak build my supplements and then I did a comparison. So far the combination I have been using, including SmartFlex III, has made a huge difference in the attitude and work ethic of my horse. He is enjoying his job in the jumper ring!

    Rated 4 out of 5 by from So far so good.... My horse has an old stifle injury, he's about 13 years old. I use this supplement to help support his joints and soft tissues/tendons/ligaments. I switched to a flatter pasture and between this and a better location for him, I've seen huge improvements. Funny thing is you never know how much something works, until you STOP using it!

    Rated 4 out of 5 by from Picky Mares... I switched to powder after having used the pelleted version of this supplement for nearly 2 years. Over time, my mares just started picking around the pellets and clearly didn't like the taste. They seem to not mind the powder poured over there feed and clean their buckets... let's hope it lasts!

    Rated 4 out of 5 by from worth trying later for my situation I bought a horse that was in serious need of better farrier services. I bought this product in hopes to offer her support while we were waiting for her hooves to grow so we could start correcting her angles. her hooves are growing and things are starting to be more comfortable for her so I only used it for two months. I may go back to using it at a later date if the need arises.

    Rated 5 out of 5 by from What a difference! I started using this on a horse that is somewhat retired from the halter class shows. He was a two time world champ in the APHA halter shows and was a little rough when he got here. Every move he made you would hear a pop or a creak and he is only 15. Now that he has been on this for a couple of months, he never comes out stiff and moves around so much easier than he did before. I hardly even hear the sounds his body used to make any more.

    Rated 4 out of 5 by from Good for senior horse I started my 18 year old TB mare on this supplement about two months ago, and I feel like it's made her more comfortable. She is primarily used as Training/First Level dressage horse. Since starting her on SmartFlex III Resilience, I've noticed she is less stiff and takes less time to loosen up. She has no trouble eating this supplement.

    Rated 1 out of 5 by from Exploding Supplement I bought this supplement for my horse, Twist. If it works, great--but for now, I'm irritated with the packaging. I bought this supplement and four of them exploded during shipping. I opened the box, and everyone's supplements were covered in white powder. I will never order these again. I switched to Smartflex Resilience III in Pellets.

    Rated 4 out of 5 by from tOUGH TO SWALLOW I bought this product over a month ago. In powder form my horse would leave it in her trough. I switched to pellets and she seems to be eating it better now. If you have a picky eater get the pellets much easier to get the at in them than the powder. As for performance she seems to be recovering from the stress of barrel racing quicker.

    Rated 5 out of 5 by from So far so good I've typically used Cosequin as a joint supplement, but decided to give the SmartFlex a try during one of the SmartPak promotions. Usually I say don't fix what isn't broken, but since I'm not entirely sure that feed-through joint supplements do more than make me feel good as an owner the sale price was appealing. I just use it as a preventative so I'm not sure how much I can speak to the effectiveness, except to say there have been no issues since switching.

    Rated 4 out of 5 by from Love overall product My horses move and feel better with the resilience over any joint supplement. If your horse is any bit of a picky eater get the pellets not the powder.

    Rated 5 out of 5 by from Great Results! Paraklesis is a registered Arabian. Poe competes in competitive distance sports (CTR and endurance). Poe has been on this product for about 2 months and I can see a difference in his fluidity. He travels down hill with bigger strides and more confidence. I think it is because his joints feel better. Poe is 12 years old and has been competing for 6 years. His long term health particularly his joint health is critical to his soundness. I think this product really helps.

    Rated 5 out of 5 by from I have been experimenting with my 8 year old QH gelding who seems to have issues getting back to work after recovering from some hoof issues, preceded by a bowed tendon when he was younger. His reaction to this supplement was positive, and I feel it made him more comfortable. Very palatable.

    Rated 2 out of 5 by from Didn't Notice A Difference The first 5 minutes I would ride my horse, he would start out a bit stiff, but would work out of it. I decided to try SmartFlex III Resilience. Unfortunately, after him being on it a few months, I did not notice a difference. Based on the recommendation of my vet, I put him on straight turmeric powder. Within a few weeks, I noticed a difference. My horse no longer started his daily work being stiff.

    Rated 5 out of 5 by from A Noticeable Difference My 7 yr old mare has been on this product for about 6 weeks. I wanted to give her the best support while in training, but did not expect to see a huge change since she is already very sound and athletic. After a few weeks, her movement was noticeably more free and forward. First time I have actually SEEN a joint supplement work!
