SmartSupplements by SmartPak
- Item #14665
Form: Powder
Maintenance Dose: 1 SmartPak Well



SmartFlex Senior was designed to support older horses in the 3 areas they need it most – joint health, digestive function and antioxidants for a healthy immune system.

For joint support, SmartFlex Senior provides 7,000 mg of Glucosamine, 500 mg of Chondroitin Sulfate, 50 mg Hyaluronic Acid and 12,000 mg of MSM. This formula contains the herbs Devil’s Claw and Boswellia, as well as the amino acid Phenylalanine, to help manage discomfort. To support healthy digestion and weight maintenance, SmartFlex Senior provides probiotics, prebiotics and enzymes. And because senior horses benefit from extra antioxidants, this formula also contains Vitamin C and the powerful free radical scavenger Super Oxide Dismutase. This outstanding formula is a customer favorite!

For even more comprehensive senior support, consider our multi-purpose formula SmartCombo Senior.

    Rated 4 out of 5 by from Great Supplement The Smartpak senior formula has helped my 25 Morgan gelding stay "young" for the past 5 years. He eats the powder formula easily and hasn't had a step out of place in years!

    Rated 4 out of 5 by from joint supplement I have 2 horses on this supplement. I started them both as a preventive measure. One has diagnosed navicular and low ring bone. I recently started hearing the one with navicular and ring bones joints start cracking. He is 21 years old and hasn't been lame since his first injections last fall. My other guy seems to be doing fine. I still have them both on the supplement, but I'm not sure if it is working or not. I've had them on it for over a year now. Not planning to take them off because it is too easy to use and I believe it must be doing something. Better than nothing.

    Rated 5 out of 5 by from My old girl looks good A year and a half ago, I wasn't sure my Paint mare that I raised from a foal (daughter of my first horse) would still be around at this time. She was 27 years old and was so stiff with arthritis I was afraid the time was coming to let her go. Also, we couldn't get any weight on her no matter how much we fed (and she often didn't finish her grain).I put her on Smartflex Senior and she finally put on a little weight. At the same time we loaded her up on Adequan and continued using it for about 6 months consistently, so I can't say for sure her improvement in the lameness is all from the Smartflex, but this year she looks better than she has in several years as far as her coat, weight and getting around the pasture. We haven't needed the Adequan during warm weather, but will probably start it up again in the winter. I attribute most of her improvement in health to the Smartflex Senior. Looks like she'll probably make it to 30 after all.

    Rated 5 out of 5 by from Perfect for old man. My senior horse has been on this for 8 years and I can't ever imagine him not having it. It was the very first supplement I put him on and the difference it has made in his life is significant. He has advanced arthritis in both knees and hips but still wanders around without pain or joint stiffness. I've even caught him running the fence lines with the young horses in the next pasture. I will continue to use this product with all my senior horses.

    Rated 5 out of 5 by from Saved my mare's LIFE!!! I had gotten a rescue horse, Terra, about three years ago and she was about 20. For two years she was 98% sound, with slight popping in her hocks. She was amazing in the hunter/jumper ring at the 2'6" as well as being shown on a competitive drill team and in the sorting pen. Last October, she was supposed to go to a show to compete in the 2'6" hunter ring as well as the week after with a student when the day before she went LAME! Dead lame walking on two legs. We tried EVERYTHING! The vet and my farrier was stumped. We were about to put her down, not wanting her to suffer when as a last resort I decided to put her on Smartflex Senior. She inhaled it and within the first week I saw a difference! Being on it for three months, she is BACK AND SOUND!!! She is cruising around at home over 2'3" jumps dragging me to them because she feels so good, and has even gone sorting a few times with a student and nearly won a buckle!!! Better yet, no more popping! Terra now has a long life ahead of her teaching many more kids how to ride and respect horses.Thank you Smartpak for saving my horses LIFE!

    Rated 5 out of 5 by from Good for my picky eater My horse was on the pelleted version of this supplement along with two others. After she broke a tooth, she started leaving the supplements in her feed bin. Switched to the powder version, and now she eats it all up! Thanks!!

    Rated 4 out of 5 by from Best Value for a Budget While the I like the SmartFlex products with 100mg of HA the best, my budget doesn't always allow for my 23yo TB (dressage/eventing) to have them each month. The SmartFlex Senior is an excellent value for leaner months. It noticeably maintains his joint health and comfort level. He works 3-4 times weekly, his gaits have maintained their integrity. There is a distinct difference as compared to when he is not on any joint supplement.

    Rated 5 out of 5 by from Best Senior Horse Maintenance I have tried many brands of joint supplements for my horses over the 13 years I have owned them; spending as much as $150 for a 2lb. bucket. Unfortunately my PercheronXAppy that REALY needed it passed away 3yrs ago at the age of 29 before I found a supplement that really worked for him, but because of the lack of preventative care he received for his joints before I purchased him I know that they do really need it. I have a 25yo Arabian gelding that has never shown signs of lameness or stiffness and he still acts as he did when I rescued him 11yrs ago. One thing that I have learned from owning many senior horses is that something that works for one horse doesn’t always work for another. The supplement that worked okay for my Percheron cross did not work at all for my Arabian, so he has spent allot of time on and off of different joint supplements. When I found Smart Flex Senior and started my horse on it I didn’t notice a difference because he is semi retired now and doesn’t get ridden much, until I talked to a neighbor that loves to sit on her porch and watch them in the field, she told me that he has started playing and running around with my 3yo Arab gelding and he now RUNS up the hill to the barn at feeding time instead of walk as he has for the past 11yrs I have owned him.

    Rated 4 out of 5 by from Giving to a 13 year old halflinger that is ridden approximately 8 to 10 hours weekly on very hilly and uneven terrain. Noticed an improvement within 8 days. My horse is still slightly sore but a definite improvement and will continue using.

    Rated 5 out of 5 by from Results in Two Weeks! My 20 year old New Forest Pony wasn't showing any signs of being stiff or sore, but would have an occasional "pop" from the hock when cantering. As a preventive measure, I wanted to start him on a joint supplement before he really needed one. After just two weeks, he was really wanting to go! All he wants to do now is canter. My two other riders also commented about how feisty and good he was feeling. Plus, he loves it! I'll admit to tasting it, just because its smells so sweet. Keeper is a really happy pony!

    Rated 5 out of 5 by from Gap Help I had added this product to my smart pak, however I was at the beginning of a cycle and needed something to fill the gap between now and the new smart pak. The customer service rep was very helpful in "filling the gap". It worked perfectly -the canister ran out just as the new monthly smart pak kicked in - Thanks again

    Rated 4 out of 5 by from Preventative Measure I have a 27 YO Arab with 27 YO teeth and he has no problems eating this supplement and no palatability problems. I have not noticed a difference in his behavior or performance, but because of his age I want him on a supplement to prevent problems. The level and type of ingredients also are what I was looking for in a senior supplement. Smart Pak Senior seems to be priced similarly to other products and I know they have good products, which is why I scored them a 4 on everything.

    Rated 5 out of 5 by from Worry Free Care I sent my senior (27 years old) trail companion off to a friend's retirement farm last summer and this has proved to be a great way to provide him with all the support he needs. He likes the Smart Flex Senior and it is keeping his quality of life worry free. He is also on Smarte Vite. I like that I can also send him support supplies like fly masks and wormers etc.

    Rated 3 out of 5 by from Pellets only. I love smartflexs other products, but will only buy pellets for now on.My mare wouldn't eat the powder and due to allergies I cant feed the pellets. Cant get any of my other horses to eat it either.

    Rated 4 out of 5 by from good quality @ good price I have been using the product for an older horse for several years and believe it has helped the mare maintain her quality of movement; Recently I started a 17 yr old retired roper on this and am going to hope for simalar good results!

    Rated 1 out of 5 by from Beware if you have even a slightly picky eater! I purchased this product on accident, I meant to purchase this in pellets. My horse won't touch it and often will leave most of her grain even with sweet feed, molasses, applesauce, etc mixed in. I have no problems what so ever with the pellets. It has been well over $100 that I threw away with this purchase. When I contacted SmartPak they told me there is nothing they could do for me even though I knew after 1 scoop this wouldn't work. Very unhappy with this purchase and won't make that mistake again. Go with the pellets if you are concerned at all your horse won't eat it!

    Rated 5 out of 5 by from This supplement is wonderful! It is hard to maintain a senior horse, even if he is a senior and is still being used as a racehorse. This product gives my horse all of the necessary maintenance he needs as a race horse; and keeps him feeling like a young gielding. Older Barrel horses needs all the support that their body can get from supplements and this product works wonders for him.

    Rated 5 out of 5 by from SmartFlex Senior test I have been using a higher dose smartflex product for several years following an injury. My horse is at a much lower work level now and has recovered as much as she is going to from the injury. I figured I could use a smartflex product more as a maintenance supplement than a rehab supplement.This one seems to be working out just fine.

    Rated 3 out of 5 by from not enough info I ordered this for my horse unaware that Devil's Claw is a forbidden substance at USEF competitions. I think it would be best for SmartPAK to alert customers to this on the descripiton. Since I compete, it wasn't the best value. Seems like a smart supplement for a retired horse.

    Rated 3 out of 5 by from Picky eater wasn't cleaning it up My horse is a pretty picky eater and he just wasn't into the powder form of this supplement. Actually, I haven't found a powder supplement yet that he will lick up from his bowl. I did switch him to the pellet form of this supplement though and he's cleaning that up just fine and it seems to be working great for him.
