    One AC is rated 4.5 out of 5 by 220.
    Rated 5 out of 5 by from Sweaty Again in Central Florida My TB gelding had begun to exhibit partial anhydrosis and I was desperate to find a solution for him. He would sweat in small patches and it was not enough to cool him. His performance in lessons and shows was suffering. We are in Central Florida so it becomes hot and humid in May and the long summer runs through to nearly October! My trainer agreed with trying One AC but cautioned that it does not work for every anhydrotic horse. I began feeding two teaspoons a day, one at each feeding. It took about six weeks but we now have results that I attribute to the supplement. He is sweating more and becomes less winded during our riding sessions, even our Saturday morning lessons when it's especially humid and unbearable. Thank you Miracle Powder Company and Smartpak!

    Rated 5 out of 5 by from It’s working for my mare! My mare overheated two days in a row - I started her on this product and she has not overheated since then.

    Rated 1 out of 5 by from Deserves ZERO stars...but that's not an option I have tried this twice now. Once last year for 5 months and now again this year for 3+ months. I have been so desperate for a solution that I took a couple people's recommendation and tried this...twice. I also did not give up after a couple months because of the advice that it can take a few months to work...ummm, NO! Moving on to acupuncture and Chinese herbs; told you I am desperate!!! Regardless, this product did NOTHING and was a waste of money.

    Rated 5 out of 5 by from Helps my 7 y o OTTB to sweat. Live in South Florida so absolutely necessary. My boy has mild to moderate anhidrosis.

    Rated 5 out of 5 by from LIFE SAVER!!!! I bought OneAC for my Thoroughbred Swagger, who was recently diagnosed with Anhidrosis. I was so devastated with the diagnosis and was extremely worried about my beloved Swagger. It is mid-October and Swagger has been on OneAC almost two months. I can tell you that Swagger is feeling better and has started to sweat in his neck area. I AM SO EXCITED! Upon further research, I JUST ordered CoolStance feed from SmartPak, which is a cool, clean feed that has MANY great reviews. I will keep you all posted on Swaggers journey, I eagerly await the arrival of CoolStance. My experience with OneAC and the lovely ladies at SmartPak has been FIRST CLASS! Really, I have leaned on SmartPak’s team so much the last two months, sometimes calling multiple times a week for guidance. Thank you SmartPak team for all you do! Your dedication has meant so much to me during this TRULY emotional journey with Swagger! Thank you again!

    Rated 5 out of 5 by from It works! My OTTB showed a few signs of anhidrosis and my vet recommended One AC. He has been sweating great and is back in competition.

    Rated 4 out of 5 by from Helps in the heat! I have a 28-year-old Cushing’s horse. A warmblood with a thick coat that has been managing his ACTH levels with Prascend but still had difficulty cooling off in the heat. Consistent body clipping and adding One AC to his AM and PM buckets has helped him manage through the North Carolina heat and humidity much more comfortably. Will start it sooner in the spring and keep him on it thru early fall next year.

    Rated 5 out of 5 by from My horse is wet with sweat!!! This was recommended by my vet after my horse developed anhydrosis last July, so A.I. have now used this for a year. Three key points to improve your outcome: 1. OneAC definitely works best if you put your horse on it for several weeks before it gets hot (I started in early Spring this year). 2. I pair it with either table salt or electrolytes daily (vets recommendation) 3. My horse is a large 1800lb draft cross who needed much higher dose than we thought- 4.5scoops twice a day (again, this dose was increased slowly under vet supervision but needs to be this high to work). Awesome product! Please sell it in a larger container!

    Rated 4 out of 5 by from Wonderful Result Did exactly what it says it will. Horse has been on it a week, and he already has a better sweat pattern and is less lethargic

    Rated 5 out of 5 by from Typical great srevice from SmartPak My sweet Kate is a senior Belgian heavy draft mule. During recent sudden heat wave found her breathing heavily, not sweating. Phone call to SmartPak got 1AC shipped next day. She hates the taste, but takes it soaked with alfalfa cubes. Sweating appropriately now.
