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 could cause more damage than it can keep up with. Joint supplements in this category are designed for horses in intense work and provide the ingredients needed to help maintain joints and connective tissue health. Tendon and ligament ingredients as well as a comprehensive selection of antioxidants are included to help equine athletes continue to thrive. This level of support is also worth considering for horses that may need additional support due to age or joint issues.

SmartFlex® Ultimate Pellets is rated 4.7 out of 5 by 96.
Rated 5 out of 5 by from Like night and day for my senior QH I have a 23 year old QH that was exhibiting some joint discomfort, especially in the hind end. It got to a point where she wasn’t wanting to pick up her front hooves (she’d have to balance on the hind legs to do so), and was becoming a problem. She was previously on the smartflex senior pellets which did help her initially, but I guess just wasn’t doing the job anymore. Since switching her to Smartflex Ultimate pellets, and the addition of Smartflax (for anti-inflammatory properties), she has been like a different horse. Took about 2 months to really kick in but her activity level is much higher. She seems perkier and more comfortable, willingly wanting to gallop all the time. And best of all she’s holding her feet up with no problem. She is on pasture 24/7, gets only a handful or two of grain as a carrier for her supplements, and gets Vermont Blend as well. I trust Smartpak products and ingredients and can definitely say they’ve made a difference for my girl. So happy to see her pain free, and not need to resort to NSAIDs!

Rated 5 out of 5 by from Great product to ad comfort to arthritic pain I believe in researching a product, especial the ingredients in which are in the product. Smartpak has very good ingredients the products in which I have used in the last 4 yrs or so. This product is a wonderful product for replacing previcox and Vet RX to help the horse move and aid comfort to arthritic and even ads relaxing comfort while horse is stalling in longer time periods in cold Minnesota nights due to artic weather we experience.

Rated 5 out of 5 by from Working GREAT! After hours and hours of exhaustive review and comparisons of ingredients, I have combined custom doses of this product with two others: Smartflex Rehab and SmartAntioxident and been using this combo for over 2 years. I just had my 12 y/o performance hunter evaluated by the vet for a routine update. Passed with FLYING colors. I try to be proactive, preventive and supportive in my horse's care. I am a big believer in science and feel like a high performance athlete deserves to have their body replenished and supported properly.

Rated 5 out of 5 by from Big Difference! I'm not one to write reviews, but this product deserves a good review! I have an 11 year old Appendix who has always loved to jump, but recently has been too stiff in his stifles to do so. In just one month, I have seen a complete change in his gait and attitude. He was becoming a little grumpy about working, but now he is happy to work again. Although it can be pricey, I highly recommend this product!

Rated 5 out of 5 by from Easy, quick, no counting or measuring. I bought this product 2 months ago and couldn't be happier. No counting, no measuring, so easy! I didn't even have to think about when to re order, the automatic arrives when you have 2 or 3 packs left. Its perfect. The storage box is big, works well and helps keep me very organized. My old man of a horse is moving great! Turns easier, better hock movement, not as stiff when he comes out of the stall. He's trying to run around with the babies at my barn! I recommend this product to anyone who wants to give their horses joints a little something special.

Rated 5 out of 5 by from GREAT product! I started my 18.2H purebred Friesian gelding on this product August 2019. He LOVES the pellets!! I do notice that he moves freer & seems to perform better also. He also has anhydrosis--non sweating. In Florida, that is very dangerous. I had him on 2 supplements to help him sweat & a beer a day which all together barely got him sweating even when in the 90's. One week after I started these Ultimate Pellets, he started sweating like crazy!! I am not sure what is in this product to make him sweat, but I am so happy for him! He sweats great in the heat of the summer & the cooler temps of the Florida Fall. So we are taking care of his joints & tendons & also his thermostat. He works so much better now!!

Rated 1 out of 5 by from GLUCOSAMINE HCL IS WORSE THAN A PLACEBO! I was SO excited about this product! My OTTB ate it, and I loved the idea that I was supporting him as an eventer - UNTIL I did plenty of research, and asked a nutritionist (she has her PhD in clinical nutrition) friend of mine - Glucosamine SULFATE is the ONLY Glucosamine that should be recommended and used! Glucosamine HCL does NOTHING! Studies show that placebos have better results than Glucosamine HCL!! SAVE. YOUR. MONEY.

Rated 5 out of 5 by from The Best Oral Joint Supplement Available My farrier recommended this product. My Clyde/TB cross is 14 now and needs a little help with minor arthritis and muscle stiffness. I had him on Cosequin ASU for the past year. Now that he's been on the Smartflex pellets for 6 weeks I'm really seeing a difference in him. I'm so impressed with this product I'm putting my other gelding on it too!

Rated 5 out of 5 by from It works! I have tried everything on my retired show mare, and after two months on SmartFlex Ultimate, her flexibility is improving!
