SmartFlex® Senior Herb-Free Pellets is rated 4.7 out of 5 by 369.
Rated 3 out of 5 by from Early Days Haven't had time to see any results yet, but I like the herb-free feature and especially the pellet form. Too much waste with granular joint supplements.

Rated 3 out of 5 by from Great Ingredients, Not Enough Results I tried this supplement on my 13yo Warmblood Cross who like most Warmbloods have early bone growth on his hocks. I wanted to get out ahead of any more progression. This had all the ingredients I was looking for, except I did not notice a significant different to keep paying this amount. I decided to go with Adequan instead. The loading does once a year seems to equal out to the same as an oral supplement and I have seen instant results.

Rated 5 out of 5 by from It's working! My gelding has been on SmartFlex for about 2 months, and I already see a difference. He is only 11, but has joint issues and has had lameness in his his right hind from an old injury. After starting him on SmartFlex he is significantly less stiff and the popping and cracking in his hind end has reduced as well. I would definitely recommend.

Rated 5 out of 5 by from Spring back in his step! My 20 yr old QH was getting very stiff in one of his knees. Noticed with trimming. And was clicking more in one of his back legs. He’s always been very active running horse all the time still was but noticed more walking to come see me then running like he always did. Thought I’d give this a try. It’s amazing difference in short time. And he’s back to his old jokester self Just generally feeling very good again.

Rated 5 out of 5 by from Very palatable, I like the ingredients It's too early to notice if it's really working, but I ordered this a few months ago and my horse seems to like it. He is not quite as stiff as he was. He enjoys eating it.

Rated 4 out of 5 by from Awesome product! I have a 17.2H 16 year old Friesian gelding that I bought this for just over month ago. It probably hasn't been enough time to really notice a difference, but I have seen some changes for the good in the way he moves & plays like a 2 year old again. He LOVES this stuff & even cleans his feeder up now. I want to ensure his joint, etc health as he gets older. He used to be my Dressage horse but REALLY loves the trails with my husband aboard.

Rated 5 out of 5 by from Seems To Be Helping Both my horses have some lameness, and both are on a different medication from the vet, along w/ SmartFlex Senior Herb-Free Pellets, and a couple supplements. Both are moving better, especially in the front end. I've also switched to a barefoot trimmer.

Rated 5 out of 5 by from Excellent product I started my 22 year old spotted saddlehorse on this 3 months ago since I do a lot of trail riding. The results are amazing. She keeps up with the youngsters and takes the mountain trails with great ease. I highly recommended this product

Rated 5 out of 5 by from Works well I have been using it for about two months on my 40 yr. old pony and she seems to feel much better.

Rated 5 out of 5 by from SmartPaks are the best! I highly recommend SmartPak senior supplements for your older horse. At 22 years old my little mare moves like a much younger horse and does not appear to have any stiffness or pain. She will remain on the SmartFlex Senior Herb-Free Pellets for the rest of her life. No matter the age of your horse, SmartPak has a supplement for him/her and at a very reasonable price. And with the SmartPaks, my horse gets a fresh packet each day. Great customer service too!!

Rated 5 out of 5 by from Good ingredients This product has everything recommended for joint support. It's easy to feed and the horses like it.

Rated 5 out of 5 by from Such a Difference I have had my 15 yr old QH gelding on this supplement for 2 months, and I've seen a big difference! He's moving better, takes less time to warm up, is more forward, and more motivated! Highly recommend!

Rated 4 out of 5 by from Hey Mikey! She liked it! When Bella wouldn’t eat the smartflex senior pellets smartpak recommended the herb free and she ate it! Yay! Momma’s happy! Thank you for all the guidance smartpak! Excellent customer service as always!

Rated 5 out of 5 by from Great product! I use this product on all of my horses (not only my senior horses) because it has everything in it that I want my horses to be on.

Rated 5 out of 5 by from Feel so good feeding my 16 yr old mare these! I'm on my 2nd tub of these. My newish mare has very clean legs for her age, no popping, clicking, etc, but wanted a preventative and supporting supplement. Of course I turned to Smartpak and am as usual very pleased! I do have a new farrier who has freed her up movement wise but i feel a difference in her swingy stride. Highly recommend the herb free supplement as it does not contraindicate with her gut or magnesium supplement.

Rated 5 out of 5 by from Love it! Love the pelleted joint supplement. Easy to feed. My horse likes the taste and eats it all. Thanks Smartpak!

Rated 5 out of 5 by from Wow! I have an 18 year old Standardbred mare with known hock arthritis on both hocks, right hock worse than left. This fall, once the weather began to turn cooler, she just seemed stiff. Walk & trot looked great. Cantering on her left lead began to feel & look a bit odd, she was beginning to bunny hop with her hinds now & then. I thought I’d try a joint supplement and after much online research, ordered Smart Flex Senior Herb-Free. Was quite skeptical that I’d see any difference as I tried numerous oral joint supplements in the past with minimal success. In the past only the oral HA gels seemed to make any difference, but since I board her and winter in Minnesota is cold, I wanted a joint supplement that wouldn’t be harmed by freezing temps. I also tried hock joint injections once but they didn’t seem to make a difference either. Well, she’s been on the supplement for 3 weeks. I can’t hardly believe the change in her! Her canter looks and feels great, especially her left lead. Very pleased with this supplement. Will definitely be ordering more!

Rated 5 out of 5 by from Works great. I bought this for my 24yr old mare that was starting to show signs of old age. Lackluster coat, gimp in her walk, just not happy After about 2 weeks of Smart flex she started to show improvement! I just finished my 1st bucket and.. Wow, what a difference in her ! I am so happy. My fur baby no longer appears to be in pain when she moves and has a much happier attitude.
Date published: 2017-11-01
Rated 4 out of 5 by from Horse likes it I first purchased the product when someone pointed out that my 18 year-old QH mare was making snapping noises in her back end as she walked. Three weeks after starting her on the product, she walked quietly and I thought she was doing better. This morning, after taking the product for about 7 weeks, there are snappy noises again. I'm not sure what to think.

Rated 5 out of 5 by from Energizer strong I have been feeding this to my now 25 yr old arab for years and he still trots down the trails like the energizer bunny, keeping up with the younger crowd. I purchased a 14 yr old arab mare 2 yrs ago and put her right on it because of her past racing career and a pelvis injury. She is doing wonderful on the always changing terrain we encounter out on the trails.

Rated 5 out of 5 by from Best joint product for the money! Easy to use as well

Rated 5 out of 5 by from Joint supplement So far this seems to be doing a great job with my 23 yr old Appy, he is trotting along much. Better and no stiffness in hid hind end like i observed a month ago!

Rated 2 out of 5 by from New Senior Formula Now Just Joint Supplement I've been giving the SmartPak Smartflex Senior Herb-Free Pellets supplement for some time now and I am really disappointed with the new formula. The old formula contained Profloratin (a probiotic formulation) and the new omits this entirely. The new formula is basically just another joint supplement at a slightly lower price than before. My horse liked the taste of the original formula pellets more than other supplements I've given him, but I haven't tried this new one yet and since it is now just a joint supplement I may shop for another brand that is geared more towards the overall needs of a senior horse (with probiotics). It's too bad that some companies will take a perfectly good product and reformulate it to presumably maximize profits.
Date published: 2017-07-14
Rated 5 out of 5 by from Senior Pellets My horse loves these pellets! He eats them out of his food first. I have only used them for one month, so I haven't really noticed a difference in his joints yet. I will update the review at a later time.
