    One AC is rated 4.5 out of 5 by 220.
    Rated 5 out of 5 by from So glad this was recommended by our vet for our COPD horse. We were so worried about her breathing and never took into consideration of her not sweating out bad toxins as well. Tried other sweating aid supplements without working. Along with sweet Olive not wanting to eat with the other supplements in her grain. The One A.C. is palatable and has made a difference in our mares health as Well! Very pleased with it! And of course with our other products from SmartPak.

    Rated 4 out of 5 by from one ac i have used one ac for the last couple of months . The horse began swetting after about six weeks. How long should i continue to use this product?
    Date published: 2018-09-26
    Rated 5 out of 5 by from Great Product! I was so upset when my horse STOPPED SWEATING. My trainer recommended starting him on One AC immediately. I followed the label instructions for the first week, but still no sweating. Then after reading posts from the Support for Horses with Anhidrosis that the a loading dosage of double or even triple would get them sweating, I tried a double dose. He started sweating within four days. After 14 days I ramped down to three scoops, then down to maintenance dose 30 days after that in his regular SmartPak. I plan to leave him on the One AC through the end of October when it should be cool enough to discontinue until late in April. Plan to restart the One AC before the warm weather starts. Adding the One AC was economical and made it easy to be sure he receives his "meds" every day, regardless of who is doing the feeding at my boarding stable or when he's at the trainer's.

    Rated 5 out of 5 by from Amazing! Bought this for a new horse that started struggling in the heat and was not sweating as much as I thought he should. My vet recommended I give this a try. Within days I noticed a difference and within 2 weeks he was a different horse. We will not go a summer season without this!

    Rated 4 out of 5 by from May be working She has been on this supplement for one month and she may be starting to sweat more. It is not dramatic and am hoping to see more with longer time on it. Easy to feed since it is a tiny amount of powder needed and doesn’t have any objectionable flavor.

    Rated 5 out of 5 by from Works.... My main rope horse suffers from the heat to the point of colic when the temps get high. I started her on One AC this spring and had no episodes this summer and it has been very hot! She sweats more easily when working and just seems more comfortable overall. Thank you for a cost effective supplement that works.

    Rated 1 out of 5 by from Didn't work for our Thoroughbred Tried this for a few months because our horse is not sweating properly. We also tried giving him stout beer for a few months and that has not worked well either so the product may be fine. It may just be that we have a difficult horse to figure out.
    Date published: 2017-08-17
    Rated 4 out of 5 by from It was helpful My gelding went from a heavy sweater to a non sweater in a week of high temps. This product works really well when I give him about two extra scoops (reason for four stars instead of five). It also works best when it's slightly humid out.
    Date published: 2017-08-08
    Rated 5 out of 5 by from It works! This has worked on 2 of my warmblood geldings. Time frame for it to kick in is pretty accurate. Sweating starts sporaticly at first.
    Date published: 2017-07-14
    Rated 3 out of 5 by from It helps my horse ever so slightly giving 2 x daily. I hate giving it a star rating because I think every horse could respond differently, so I did give just 3 , but for my particular horse only.

    Rated 3 out of 5 by from No difference I added this to my horse's smartpak's for the last two months. I have not noticed any improvement in his ability to sweat.

    Rated 5 out of 5 by from Keeps my mare sweating in the Texas heat Last year I thought I might be able to go without this as my mare seemed to be doing really well on the sweating front. I realized my mistake when she completely shut down right after it started getting hot. This year I'm not taking any chances and have had her on it since early spring. So far so good. She sweats more than my other horses even on 90 degree, 90% humidity days.

    Rated 5 out of 5 by from Good for anhydrotic horses I add these OneAC to our spring/summer/fall feeding routing to help us through the hot weather and heavy work of summer training and show season. My gelding suffers from anhydrosis and starting him in the Spring on OneAC helps him to sweat throughout the hot and steamy weather. He's big - so we've switched to the SmartPak option rather than the bulk (which we used for two years) for ease and clean up. He's always excited about his meals and adding this powder doesn't deter him one bit. OnceAC in combo with our summer routine really help us through the hot and steamy weather.
    Date published: 2017-05-17
    Rated 5 out of 5 by from One AC saved our show season! After a week of the Oklahoma summer heat, my daughter's gelding stopped sweating and began puffing hard when worked. We started him on One AC and within a few weeks he was back in the show pen and doing great! Such a terrific product!

    Rated 5 out of 5 by from Excellent supplement. I bought this supplement to help my horse with a temporary bout of anhydrosis, and it seemed to help him a lot.

    Rated 5 out of 5 by from Don't give up on this! It took about four weeks for this to start kicking in for my 14 year old gelding. I was worried that it wasn't working at all, and then one day, suddenly, he was sweating! It's been six weeks now, and he's back to his old, perky self, sweating normally and feeling 100% again, even in our humid, triple-digit Houston heat. So if you don't see results in two or three weeks, don't give up. I guess it just takes a little longer to work for some horses. Also, my guy is a SUPER picky eater. He is suspicious of everything, and will flat out refuse to swallow a lot of things no matter how hard you try to disguise them. But he eats this powder on his grain with no problem at all!

    Rated 5 out of 5 by from FINALLY we have sweating!! I have a Friesian mare that I purchased last December. This was our first summer together and I was not prepared. She has a stifle issue and has to stay in consistent work, but as the weather got warmer, my mare stopped sweating, was overheating, and couldn't endure more than a 15 min ride even in the early morning or evenings. I live on the Gulf Coast and the heat and humidity can be brutal. I almost gave up on the One AC after 6 weeks and only getting a little sweat under the saddle pad and girth. I started looking into other options and was ready to call Smartpak asking for a refund. This past weekend made 7 weeks and FINALLY we have SWEAT! Had an early morning lesson and by the end of it, my mare was drenched on her neck and chest areas. I couldn't believe it. I purchased the Smartlytes along with the One AC to help increase her water intake and she is finally able to to go a full 45 minute ride without overheating. I guess depending on the horse, it can take awhile to kick in, but it was definitely worth it. FYI...she is on the Smartpak 2 scoops per day ration. It's possible that if I had upped the dosage, it may have kicked in sooner, but I am just glad to see results!

    Rated 5 out of 5 by from One AC is great! I have given my horse Nate One AC for just a few weeks and already noticed a difference. He is sweating more and drinking more. Nate is enjoying his first Texas summer after residing in Michigian and Canada previously. I was concerned about the transition, and One AC has truly helped!
    Date published: 2016-08-20
    Rated 1 out of 5 by from Does Not Work Every horse is different, and One AC was started in March, 2016. I give 3 1/2 scoops twice a day to my 1400 pound horse. We are now heading into August, and my horse only sweats under the saddle and girth. He gets beer, extra salt and daily supplements. I just started on Perspercide, but no luck yet. I did the Equiwinner patches for 10 days and those did not help. Not sure what to do next. Maybe I'll try Refresh by Platinum. I wish everyone the best with anhidrosis and this awful summer heat in Florida.

    Rated 5 out of 5 by from great product easy to use I have had my 24 year old palimino quarter horse gelding on One AC for 2 years . He had an non sweating attack... no sweating and high temp and breathing rate. had to rinse and scrape multiple times . vet suggested One AC and I have used it now for two summers and no issues since. and this summer is HOT.

    Rated 5 out of 5 by from Sand Clear/Manure-Eating Dogs-Hurrah! I have used Sand Clear monthly packets for years but, I never dreamed they would be so good at cleaning the sand out of the gut of my horses. Unfortunately, my Australian Shepherd dog, as well as my 2 Teddy Bear Puppy-type dogs, are always getting into the manure pile in their quest for horse droppings (treats for them). I was alarmed when the Aussie vomited in the house repeatedly one morning. The final vomitus produced a cupful of sand with mucus. I thought how awful it was for the dog to have that much sand in her stomach.I called the Vet, thinking something was very wrong. But, we both decided that it was a natural occurrence, after the Aussie's dining habits were exposed. I realized that the Sand Clear was doing it's job. The sand absorption by the Sand Clear was so good that my dog became filled with sand after dining on her special manure diet. All was well with my dogs and horses. I am now working on an underground fence to keep the manure piles off-bounds for the dogs.
