    Ex Stress is rated 4.2 out of 5 by 73.
    Rated 5 out of 5 by from Incredible! I tried all the calming products. Ex Stress is the one and only that produced consistent, positive effects in my mare. For any horse that is deficient in the B vitamins, this is definitely the product to use. My mare became an amazingly calm, enjoyable, easily trainable horse.

    Rated 5 out of 5 by from Awful Eiffel Isn't Awful Anymore! My daughter's "hard-to-handle" Welsh-TB pony Eiffel (aka Awful Eiffel) has been on Ex-Stress for about a month now. With some changes in his feed and the addition of this supplement, he is like a different pony! He is calm and responsive to her without that "sedated" look that other supplements have caused in the past. I have just recently ordered the Ex-Stress for my off-track TB mare and I can't wait to see how she responds to it! This supplement is great, and so are y'all!

    Rated 5 out of 5 by from Love it I had bought a new mare that got really sensitive during her cycle. Just edgy, so I tried Ex-stress to see if it would take the edge off. It really seems to work. I can now ride her during her cycle and she is not as jumpy or edgy.

    Rated 4 out of 5 by from Ex-Race Horse I have a 'free spirited' Thoroughbred who's an ex-race horse. He raced for eight years and is only 11 years old. My horse Ben still has that natural racing instinct in him. Before putting him on Ex Stress he would spook going out of gates that sounded like the starting gates at the track and when spooked under saddle he would speed off like he was competing in a race. No other calming supplement has ever worked; Ex Stress has not only helped him be more safe to be around, but it's given me the confidence that Ben won't put himself and me, his rider, in danger. Thank you Ex Stress!

    Rated 5 out of 5 by from Excellent results Ex Stress is wonderful! I noticed a difference in a short period of time, and the horse only gets better day by day. Excellent choice for calming if you don't like the idea of using herbs or other ingredients that have a "sedative property." My horse still has all the energy; he just can control it now and be relaxed!

    Rated 5 out of 5 by from Great Product for Calming This product works so well that I still can hardly believe it. I have two young horses, an old off the track TB, and a Grand Prix dressage horse. It works for all of them. I try to use it at least a week or two before a show or long hauling. It settles the horses into new surroundings, keeps them calm at show, etc...I give it to one of my young horses who is very spooky and excitable and keeps him focused. He is on it all the time. This is a must to have in your feed room at all times and when you travel. Thank you Ex Stress!

    Rated 5 out of 5 by from Great supplement! I started this supplement on a very nervous "worrier" type horse. He is shown a lot, and basically gets himself worked up, so he doesn't eat well and will get a bit "high" at some shows. Within a week I noticed him being calmer and more focused in the show pen and he was eating all of his food! Highly recommended!

    Rated 5 out of 5 by from Fast-acting calming supplement I actually first started using this product because I got a free 2-week sample. I gave it to my edgy, nervous, spooky Oldenburg mare and noticed a difference within a week and a half. She was way more focused and calm, was less tense and didn’t spook as often. She also started jumping rounder and her muscles were less sore. Great!
