Rated 5 out of 5 by from Easy easy easy Been feeding Smartpaks to all of my equines who are aged. My eldest horse Smuggler is 26 and he looks wonderful. Could I buy each of the supplements Al-a-carte and save some money? Probably but I'm happy to pay a little extra for the ease of use and convenience of Smartpaks. I would recommend these to anyone

Rated 2 out of 5 by from Mare diagnosed with Vit E deficiency after 3 month So, I ordered this for a mare that had a terrible case of scratches. (She lives in a converted hayfield, not mud, and the grass is not long.) Despite being on 2nd cut hay, pasture, and about 8 lbs of a 12:14 feed that is 20% fibre, I thought maybe she was "missing something", so I ordered her this supplement. After 3 months, the mare is eating more and more food, losing weight, has poor muscling, no tail tone, and still has scratches! Vet came out and suspected a Vitamin E deficiency. I told the vet that the mare was on a supplement that contained one of the highest quantities of Vitamin E found in "normal dose" supplements. Lab confirmed mare has a severe Vitamin E deficiency. :( Don't know if the mare has an absorption problem, or perhaps without this supplement her numbers would be even lower...

Rated 4 out of 5 by from Good stuff! I bought this a couple of months ago after my young horse (whom I had going SO well) decided to buck circles around his mother in the turnout and threw his back out. A veterinarian friend suggested vitamin E and C to help with muscle repair and after doing much shopping around, this product contained the highest levels of both for the best price (with the added bonus of grape seed extract). He seemed to feel better (more full of himself) soon after starting this stuff. I may not keep him on it ALL the time once I finish the bag I got, but I think I will keep some on hand for when he's in heavier work.

Rated 5 out of 5 by from Peace Of Mind I can't really say if it is working or not, i put my horse on it because he has a sarcoid on his eyelid and i have read success storys using antioxidants. I know its a long shot but worth a try. My hopes at least is it will help keep it benign. I feel good knowing im keeping his immune system healthy.

Rated 3 out of 5 by from Great product, but ulcers came back on it. I was really excited to start my horse on this product, as Vitamin C had been recommended to me by my vet to help his breathing in humid conditions. I had him on it for just over a month and had to stop it and cut it out of all his smart paks because he stopped eating and was showing signs of getting his ulcers back. This product was the only change in his diet leading up to his refusal to eat. Two days off SmartProtect and he was back eating like normal and acting normal again. I was really hoping to be able to keep him on it for the respiratory benefits, but his stomach was too sensitive to be able to leave him on it. I would be extremely happy if SmartPak could come up with a natural vitamin C supplement that is easy on the stomach.

Rated 5 out of 5 by from Great product My qh horse seemed to always have an issue with getting hives from shots, bug bites, etc. But since he has been on Smartprotect we have had no issues.

Rated 5 out of 5 by from Great Product My horses all contracted the Strangels virus. I put my horses on this product towards the end of their healing process. In one month they were not only getting their weight back, but seemed to get well faster than other horses on the property.

Rated 5 out of 5 by from Great for high doses of Vitamin E I originally put my horse on this when there was potential that he had EPSM, lymes or both. My vet wanted him on 5000iu of vitamin E and it was tough finding supplements to get the count without flooding his food with powders. Also there are other volumes of antioxidants and anti-inflammatories in it. I will be keeping my horse on this for the long term, I do think this helps keep him at his best health. My horse is not a picky eater, and ate this right up as expected.

Rated 5 out of 5 by from Super product!! I have had my 18 yo QH gelding on this product for several months. He was retired from barrel racing last spring due to poor lung health (he is a bleeder). He always had a cough despite being on Ventipulmin. He no longer coughs and some of the "roaring" issues have stopped. He plays like a colt now - I'm thinking he'd like to go back to work!!

Rated 4 out of 5 by from great for older horse I have been using this for almost a year. My 23 year old Paint Mare never had a good tail - I am starting to see a real difference. Very happy with this product..

Rated 4 out of 5 by from Our horse has had terrible allergies this year, worse than ever. We tried SmartProtect to see if it would help relieve his itching. Since being on the product, I have not seen him scratch his entire body like he was before. I think the product has helped relieve some of his allergy issues.

Rated 5 out of 5 by from Oh, wow! I stayed away from SmartPak for years due to the price. Well, silly me! My 29 year old Arabian mare has done so, so much better with this supplement that it is hard for me to believe!
Date published: 2013-08-21
Rated 5 out of 5 by from It seems to be working! Sarcoids, sarcoids, sarcoids -- the bane of poor Larry's existence... We have a wonderful young gelding who unfortunately developed sarcoids as a 3-year old -- with the most problematic one being right in the corner of his mouth making it impossible to even think about riding him with a bit and even some hackamores depending on the shank and possibility of irritating the growth. After all sorts of treatments -- surgery, lasering, creams, salves, etc. we gave all of that a rest and I added the SmartProtect Pellets to his daily supplements. The sarcoids look the best they have looked in the entire 1.5 years we've had Larry -- I don't know if it's directly related but I'd like to think so and we'll just keep doing what we're doing!

Rated 5 out of 5 by from What a difference ! In combination with SmarkPak Digest Ultra, Bugs seem to be recoving from the EPM better than before . Weight gain and a spring back in his step. Going on short trail rides feels Great. Thank you very much

Rated 5 out of 5 by from Very Complimentary Worked well as a complimentary supplement for support for a horse being treated for Lyme's Disease. A little low on the L-Lysine, though, could be higher.

Rated 5 out of 5 by from Great For Skin! My picky eater eats this supplement right up which is an added bonus for me. I originally decided to try this supplement because of the amount of Vitamin E it had and for the price it was unbeatable. My horse tends to get little scabs around his neck and high doses of Vitamin E seem to help. This supplement more than exceeded my expectations. His skin not only looks great but he seems to feel great as well. His personality and health has been steady so far! I've noticed a change in him and nothing else has changed in his environment!

Rated 4 out of 5 by from good insurance I switched to this product after SmartTLC was discontinued, and so far, so good. My horses (aged geldings) find it very tasty and I've seen no problems associated with it. I hope it's helping to keep them healthier and more comfortable than they might otherwise be!

Rated 4 out of 5 by from Good...but haven't seen results yet My mare LOVES these pellets and that is amazing coming from a mare who dislikes apples! They smell so good it's a wonder I don't fight her for them....The reason I gave this product 3 stars for 'Value' is that I have not seen any improvement in my horse's condition. Her immune system has been weak for awhile now so I thought SmartProtect would help, but I've seen her nose running even after 7 weeks of it! Maybe it hasn't been long enough yet...I dunno. Otherwise, I would definitely recommend this supplement for somebody who has a picky eater.

Rated 5 out of 5 by from reasonable substitute I had 2 elderly horses on a now discontinued Smart product, and SmartProtect was suggested as a substitute. So far, so good. My old boys seem at least as happy and comfortable with this as they were with the old product. Absolutely no problem with palatability, they would eat it as a treat!
Date published: 2012-08-07
Rated 4 out of 5 by from Seeing Improvement My horse has Cushings and last year we fought with many small side infections- since using the protect pellets there have been very little immunity problems. I also like the pellets compared to the powder- much easier to use and seems to be more palitable to my horse.

Rated 4 out of 5 by from Great Product! This product has helped my horse reduce itching during the allergy months. Also helps keep his coat shiny and in good overall health while traveling to shows and keeping up with the lesson schedule.

Rated 5 out of 5 by from A Favorite Product I've used Smart Protect Pellets for 6 months and am very pleased with how it helps my horses. I chose it because of the ingredient, Grape Seed Extract. I've taken Grape Seed Extract and it helps joint discomfort, I believe better than Glucosamine and Chondroitin products. Currently, for summertime I made a switch from Smart Protect Pellets to Smart Bug Off which also has Grape Seed Extract plus ingredients to repel flies. Like most people, I can't afford buying every product that I like so I have to trade off now and then. I also like Smart TLC Pellets and Smart Tendon. My horses do very well on these three products.

Rated 5 out of 5 by from great all around pellets I use these on my 15 yo QH and my 28 yo Morgan and what a difference this supplement has made on both of my horses. It seemed to be the very vitamin that they were missing. I took my 28 yo Morgan off of the smartprotect pellet and he got an infection so he will never be without it again!

Rated 5 out of 5 by from Healthy, Healthy Horse! I've used this product for approximately a year and love the results. I started using it because my horse has allergies and I couldn't figure out the cause. His eyes would run and get goopy even when the flies weren't around. The ointment from the Vet only worked for a few hours. This product really has made a difference and I know it's working around the clock. Last year, a horse at the stables brought a virus back from a show. Every horse caught it except for my horse and one other boarded horse. I don't know for sure if this product truely helped prevent it or if we were just lucky. I do know that I trust SmartPak to have great products and the highest quality I can provide for my horse!

Rated 5 out of 5 by from great joint product this has really helped all my 25 year old quarter/morgan has never moved better, and its really helped my mare with her skin allergies also..... I will definetly keep using it for inflamation and keeping joints flexible!! cant beat it for the price and horses gobble it up!! thanks for this product

Rated 5 out of 5 by from Help for Performance Horses High potency antioxidants are a key component in keeping our performance horses in top shape, and we found a great choice through SmartPak. However, it is only offered in powdered form and while our mare devours it, our senior gelding refuses it. To find a comparable product, I turned to SmartProtect because it contains generous levels of key ingredients, and it is offered in pelleted form. It's a staple in my gelding's SmartPak to help keep him fit and performing his best.
Date published: 2011-03-31
Rated 5 out of 5 by from Another product goes to the pellets I feel like a SmartPak stalker because I'm always checking to see which products in powder have been switched over to a pelleted version. My horse doesn't get any grain--just a multi-vitamin--so i don't have anything to mix his supplements in, therefore they HAVE to come as pellets. Since I'm convinced of the value of antioxidants like Vitamin E, Vitamin C, grape seed and others even though you may not see dramatic and obvious improvement, this is cheap insurance to protect his valuable tissues. And if it helps with the aging process, so much the better!
